DETAILED DESCRIPTION

(12) In the context of this application, the expressions axial and axial direction relate to a rotation axis of the compressor 100 or of the adjustment ring 210. With reference to the figures (see for example FIG. 1A or FIG. 3), the axial direction of the compressor 100 or of the adjustment ring 210 is represented with the reference sign 22. A radial direction 24 relates to the axis 22 of the compressor 100 or of the adjustment ring 210. A circumference or a circumferential direction 26 likewise relates to the axis 22 of the compressor 100 or of the adjustment ring 210. A tangential direction 28 relates to an orientation substantially orthogonal to the radial direction 24. In principle, orientations and directions are to be interpreted according to these explanations, except when an axial/linear/radial/circumferential/tangential or other orientation/direction relates explicitly to another object (e.g., oblong base body).

(13) FIGS. 1A and 1B show the compressor 100 according to the invention for a supercharger 10. The compressor 100 comprises a compressor housing 110 having a compressor inlet 112 and a compressor outlet 114. The compressor 100 furthermore comprises an adjustment mechanism 200 and an actuator device 300. In FIG. 1A, an inlet nozzle 130 is mounted on the compressor housing 110, in the zone of the compressor inlet 112, which is why the adjustment mechanism 200 is only visible in FIG. 1B. The adjustment mechanism 200 comprises an adjustment ring 210 and multiple shutter elements 220 for changing an inlet cross section 112a of the compressor inlet 112. The actuator device 300 comprises a drive unit 310 and a coupling unit 320. The actuator device 300 is coupled to the adjustment mechanism 200 via the coupling unit 320 in order to move the adjustment mechanism 200 between a first position and a second position. In this process, the drive unit 310 can move the coupling unit 320, which in turn transmits the movement to the adjustment mechanism 200. The adjustment mechanism 200 is designed to move in such a way that the shutter elements 220 can reduce the inlet cross section 112a or unblock it again. This becomes clear upon examination of FIGS. 5A and 5B, which show a closed position and an open position, respectively, of the adjustment mechanism 200. The first position (FIG. 5B) corresponds to an open position of the adjustment mechanism 200 and the second position (FIG. 5A) corresponds to a closed position of the adjustment mechanism 200. The inlet cross section 112a is maximal in the open position of the adjustment mechanism 200. In contrast, the inlet cross section 112a is reduced in the closed position of the adjustment mechanism 200. In other words, this means that the inlet cross section 112a is maximally reduced but not necessarily closed in the closed position of the adjustment mechanism 200. This means that there is a minimal inlet cross section 112a in the closed position of the adjustment mechanism 200. The inlet cross section 112a is maximal in the open position of the adjustment mechanism 200. Various intermediate positions such as those illustrated in FIGS. 3 and 6B are also settable. The surge behavior of the compressor 100 can be improved by changing the inlet cross section 112a. In other words, a characteristic map-stabilizing measure (kennfeldstabilisierende Maßnahme (KSM)) or characteristic map-expanding measure can be implemented, which in turn improves the operational properties and operational range of the compressor. The fact that the drive unit 310 can move the adjustment mechanism 200 directly via the coupling unit 320 permits a compact design. Furthermore, the implementation of the actuator 300 enables an implementation solely by the drive unit 310 and the coupling unit 320 without the need of, for example, additional complicated transmission and/or gearbox units. In sum, provision can be made of an improved compressor 100 with a compact system with simple construction for stabilizing the characteristic map of the compressor 100.

(14) The coupling unit 320 shall be explained in more detail with reference to FIGS. 3 and 5A. Basically, the coupling unit 320 comprises an oblong base body 322 with a first end section 324 and a second end section 326. The first end section 324 is coupled to the drive unit 310. The second end section 326 is coupled to the adjustment mechanism 200. In other words, this means that the first end section 324 can be coupled directly to the drive unit 310 (see for example FIG. 3) and that the second end section 326 can be coupled directly to the adjustment mechanism 200 (see for example FIGS. 5A and 5B). The second end section 326 is preferably in direct operative engagement with the adjustment ring 210. As an alternative or in addition, the second end section 326 can be in direct operative engagement with one or a plurality of the shutter elements 220. As an alternative to direct coupling, the first end section 324 can also be connected to the drive unit 310 via further elements (e.g., 325), as explained in detail further below with reference to FIG. 6A. The second end section 326 can likewise be connected to the adjustment mechanism 200 via further elements (e.g., 327), as explained in detail further below with reference to FIG. 4.

(15) The adjustment mechanism 200 further comprises multiple stops 116 (see FIGS. 2A and 2B). The stops are designed to limit a movement of the shutter elements 220 and of the adjustment ring 210 in the first position and in the second position. Accordingly, the shutter elements 220 each comprise a coupling element 222. The adjustment ring 210 comprises corresponding shutter recesses 216, one for each coupling element 222. The coupling elements 222 are operatively coupled to the shutter recesses 216 so that the shutter elements 220 can be moved via the adjustment ring 210. The stops 116 are implemented by a suitable geometric designing and dimensioning of the coupling elements 222 and of the shutter recesses 216. For example, the shutter recesses 216 and/or the coupling elements 222 can be configured in such a way that only a maximum relative movement is possible, beyond which a type of tilting occurs that prevents any further relative movement of the shutter elements 220 relative to the adjustment ring 210, particularly in the open position of the adjustment mechanism 200 (see FIG. 2B). The shutter elements 220 can be configured and/or dimensioned in such a way that they, particularly in an open position of the adjustment mechanism 200, can touchingly contact the respective adjacent shutter elements 220. The adjacent shutter elements 220 can come into touching contact, particularly in the circumferential direction 26, such that any further movement is prevented (see FIG. 5A). A movement of the shutter elements 220 and consequently also a movement of the adjustment ring 210 in the closed position can thus be limited. This means that the stops 116 are implemented in the open position of the adjustment mechanism 200 by a corresponding geometric coordination of the coupling elements 222 and of the shutter recesses 216, and in the closed position of the adjustment mechanism 200 by a corresponding geometric designing of the shutter elements 220 or mutually abutting edges of the shutter elements 220. As an alternative to this, at least one (not illustrated) physical stop can be provided on the compressor housing 110. This can be implemented in the form of, for example, a projection or a protrusion, which protrudes from the compressor housing 110. The stop can limit a movement of the coupling unit 320 and/or a movement of the adjustment mechanism 200 in the first position and/or in the second position. In particular, the stop can limit a movement of the adjustment ring 210 and/or a movement of one or a plurality of the shutter elements 220 in the first position and/or in the second position.

(16) In principle, a distinction can be made between two different designs of the coupling unit 320. The drive unit 310 can also be configured in correspondingly different ways. One of these designs is a linearly movable coupling unit 320 (see FIGS. 1A, 1B, 3, 4) and the other is a rotationally movable coupling unit 320 (see FIGS. 5A, 5B, 6A, 6B). This means that the drive unit 310 can be designed to move the coupling unit 320 linearly along an axis 322a of the oblong base body 322 between a first position and a second position. As an alternative, the drive unit 310 can be designed to move the coupling unit 320 in rotation along an axis 322a of the oblong base body 322 between a first position and a second position. In both embodiments, the second end section 326 engages with the adjustment mechanism 200 in such a way that, in the first position of the oblong base body 322, the adjustment mechanism 200 is situated in its first position. The second end section 326 furthermore engages with the adjustment mechanism 200 in such a way that, in the second position of the oblong base body 322, the adjustment mechanism 200 is situated in its second position.

(17) The following embodiments relate to designs in which the coupling unit 320 is movable linearly along the axis 322a of the oblong base body 322. In the design according to FIG. 3, the second end section 326 comprises a recess 212 and the adjustment ring 210 comprises a protrusion 214. As an alternative, the second end section 326 can also comprise a protrusion 214 and the adjustment ring 210 a recess 212. The recess 212 and the protrusion 214 are in operative engagement with each other. In the example shown in FIG. 3, the recess 212 has an extension oriented orthogonally to the axis 322a of the oblong base body 322 and orthogonally to the compressor axis 22. As an alternative and if the adjustment ring 210 comprises the recess 212, the recess 212 can extend in a radial direction 24. A compensation of the radial offset between the coupling unit 320 and the adjustment ring 210 during the movement is thus achievable, since the coupling unit 320 is moved in a tangential direction 28 with respect to the adjustment ring 210. The coupling unit 320, in particular the oblong base body 322, is thus arranged in a tangential direction 28 with respect to the adjustment mechanism 200, particularly in a tangential direction 28 with respect to the adjustment ring 210. More precisely, the coupling unit 320 or the oblong base body 322 is arranged in a tangential direction 28 of the compressor 100 and offset inwardly in a radial direction 24 so that it can be coupled to the adjustment ring 210. A linear movement of the coupling unit 320 can thus be converted to a rotary movement of the adjustment ring 210. The protrusion 214 can extend substantially in an axial direction 22 of the compressor 100. The protrusion 214 can furthermore extend in a substantially axial direction 22 into the recess 212. The protrusion 214 can be bolt-shaped or pin-shaped, for example. As an alternative, the recess 212 can be configured simply as a depression, e.g., as a groove. The first end section 324, for example, can be configured as an extension of the oblong base body 322 and coupled directly to the drive unit 310 (indicated by dashed lines in FIG. 3), in order to receive a linear movement or absorb linear forces.

(18) As an alternative to the preceding design, the second end section 326 can comprise a three-joint mechanism 327 (see FIG. 4). The three-joint mechanism 327 is operatively coupled to the adjustment ring 210 and designed to convert a linear movement of the coupling unit 320 into a rotary movement of the adjustment ring 210. A compensation of the radial offset between the coupling unit 320 and the adjustment ring 210 during the movement is thus achievable, since the coupling unit 320 is moved tangentially with respect to the adjustment ring 210. The compressor housing 110 comprises a drilled hole 117 (see FIG. 7). The oblong base body 322 can enter the compressor housing 110 through the drilled hole 117. A bushing, in which the oblong base body 322 is slidingly arranged, can also be arranged in the drilled hole 117 (shown only in the context of a rotationally movable coupling unit 320). In addition, the drilled hole 117 can be arranged in a tangential direction 28 (of the adjustment mechanism 200 or of the adjustment ring 210). More precisely, the drilled hole 117 is arranged in a tangential direction 28 of the compressor 100 and offset inwardly in a radial direction 24.

(19) The following embodiments relate to designs in which the coupling unit 320 is movable in rotation along the axis 322a of the oblong base body 322, and in which the second end section 326 is fork-shaped (see FIGS. 6A and 6B) or pin-shaped (see FIGS. 5A and 5B). The second end section 326 projects radially away from the axis 322a of the oblong base body 322. The second end section 326 is in operative engagement with a corresponding recess 212 in the adjustment ring 210. As an alternative or in addition, the second end section 326 can be coupled to a corresponding protrusion 214 of the adjustment ring 210. In particular, this is the case if the second end section 326 is fork-shaped (see FIGS. 6A and 6B). The second end section 326 can extend, in particular in an axial direction 22 of the adjustment ring 210, into the depression 212 of the adjustment ring 210. In particular, the second end section 326 can engage operatively, in the axial direction 22, with the adjustment ring 210, i.e., engage operatively with the depression 212 and/or protrusion 214 thereof. In the case of a depression 212, the latter can have an extension in a tangential direction 28 in order to compensate for a radial offset between the coupling unit 320 and the adjustment ring 210 during the movement. As an alternative or in addition, for the same purpose the second end section 326 can be configured, at least in a region which engages with the recess, as correspondingly smaller than the recess 212, as shown in FIGS. 5A and 5B. As can be inferred from FIG. 5C in particular, the recess 212 can also have an extension in a radial direction 24 and optionally be open to the outside in a radial direction 24. As an alternative, the recess 212 can also be configured simply as a depression, e.g., as a groove.

(20) As shown in the example of FIG. 6A, the first end section 324 can comprise a lever 324a and a rod 325 coupled thereto. In a manner similar to the coupling of the second end section 326 and the adjustment ring 210 from FIG. 3, the lever 324a can have a groove-like recess (not illustrated) in order to compensate for a radial offset relative to the axis 322a of the oblong base body 322. The lever 324a projects radially away from the axis 322a of the oblong base body 322. The rod 325 is coupled directly to the drive unit 310 in such a way that the rod 325 is movable linearly along its axis 325a by the drive unit 310. A conversion of the linear movement of the rod 325 into a pivot movement or a rotation of the lever 324a about the axis 322a of the oblong base body 322 is possible because the rod 325 is arranged tangentially with respect to the axis 322a of the oblong base body 322 (and offset radially outwards from the axis 322a of the oblong base body 322). Although this example is shown only in the context of a fork-shaped second end section 326, it is equally applicable in a design with a pin-shaped second end section 326 and should therefore not be construed as a limitation to such a design.

(21) As an alternative to the preceding design, the drive unit 310 can be designed to generate a rotary movement (see FIG. 6B). For this purpose, the first end section 324 is coupled directly to the drive unit 310 and designed to receive a rotary movement. The first end section 324 is configured as an extension of the oblong base body 322 and is coupled directly to the rotary drive unit 310 in order to receive a rotary movement or absorb rotary forces. Although this example is shown only in the context of a fork-shaped second end section 326, it is equally applicable in a design with a pin-shaped second end section 326 and should therefore not be construed as a limitation to such a design.

(22) As illustrated by way of example in FIG. 6B, the compressor housing 110 comprises a drilled hole 117. The oblong base body 322 can enter the compressor housing 110 through the drilled hole 117. A bushing 118 (not visible), in which the oblong base body 322 is rotatably mounted, is also arranged in the drilled hole 117. The drilled hole 117 is arranged in the compressor housing 110 in a radial direction 24 of the compressor 100. As an alternative, the drilled hole 117 can be arranged in the compressor housing 110 in an axial direction 22 of the compressor 100.

(23) The following statements again relate to both designs of the coupling unit 320—i.e., to both linearly movable and rotationally movable coupling units 320.

(24) In the examples shown, the drive unit is configured as a pneumatic drive unit 310 (e.g., FIG. 1A) or as an electric drive unit 310 (e.g., FIG. 6B). As an alternative, the drive unit could also be configured as, say, a hydraulic drive unit 310. In designs in which the drive unit 310 is pneumatic, the drive unit 310 can be fluidically coupled with a line section 318 downstream of or in the area of the compressor outlet 114, as indicated schematically in FIG. 1B. What is essential here is that the line section 318 is arranged or coupled in the high-pressure range of the compressor 100. This means that the line section 318 can be arranged downstream of the compressor wheel 120. The advantage of this is that the drive unit 310 can be controlled in a self-regulating manner directly via the high-pressure range of the compressor 100.

(25) The compressor 100 furthermore comprises a fail-safe device 312. This fail-safe device 312 is illustrated schematically in FIGS. 3 and 6B. The fail-safe device 312 is designed to move the adjustment mechanism 200 into a safety position and hold it therein. For example, the fail-safe device 312 can be configured to operate in the event that a (correct) functioning of the drive unit 310 is impaired or if the drive unit 310 is not working. For example, the fail-safe device 312 can be activated by an interruption of the power supply and/or of the compressed air supply and/or by an overload of the compressor 100. The safety position can correspond to the first position of the adjustment mechanism 200 or to the second position of the adjustment mechanism. The fail-safe device 312 is preferably designed to move the adjustment mechanism 200 into the first position in which the inlet cross section 112a is maximal. In other words, the safety position preferably corresponds to the first position of the adjustment mechanism 200 or rather the open position of the adjustment mechanism 200. The fail-safe device 312 can comprise, for example, a spring element, which pretensions the adjustment mechanism 200 and/or the drive unit 310 in a position. In the example of FIG. 3, the fail-safe device 312 is coupled to the drive unit 310.

(26) In the example of FIG. 6B, the fail-safe device 312 is coupled to the adjustment mechanism 200 or to the adjustment ring 210. A combined coupling to the drive unit 310 and to the adjustment mechanism 200 is also possible. If the fail-safe device 312 is coupled to the drive unit 310, the fail-safe device 312 can be designed to move the coupling unit 320 in such a way that the coupling unit 320 in turn moves the adjustment mechanism 200 into the safety position. If the fail-safe device 312 is coupled to the adjustment mechanism 200, the adjustment mechanism 200 can also be moved into the safety position independently of the coupling unit 320 and/or the drive unit 310 in the event of, say, a defect in the coupling unit 320, in particular a breakage of the coupling unit 320.

(27) The drive unit 310 can be arranged directly on, in particular fastened to, the compressor housing 110. To this end, the compressor housing 110 can be provided with a corresponding flange 119 (see FIG. 7), on which the drive unit 310 can be mounted. Optionally, the flange 119 can comprise a gasket groove 119a with an O-ring 119b. Leakage can thus be prevented or at least limited.
