DETAILED DESCRIPTION
[0034] FIG. 1 shows a valve cartridge 1 in a side view. Valve cartridge 1 has a cartridge housing 2 in the manner of a headpiece. Cartridge housing 2 can be screwed, for example, into a housing of a sanitary fitting. A valve stem 3, which is rotatably mounted in cartridge housing 2 about an axis of rotation 4, extends through cartridge housing 2. Axis of rotation 4 extends concentrically here to a longitudinal axis 19 of valve stem 3. A bottom part 20 is attached at a longitudinal end of valve stem 3.
[0035] Bottom part 20 has on its underside first pins 21, with which the bottom part is held nonrotatably, for example, on the housing of the sanitary fitting after valve cartridge 1 has been mounted. At the same time, bottom part 20 is rotatably attached to valve stem 3, so that valve stem 3 is rotatable relative to bottom part 20 after valve cartridge 1 has been mounted. A passage disk 6, which is held on the top side of bottom part 20 by second pins 22 nonrotatably relative to bottom part 20, is mounted on bottom part 20.
[0036] A control disk 9, which is pressed by a spring element 23 onto passage disk 6, is disposed on passage disk 6. As a result, a sealing plane 24 is formed between control disk 9 and passage disk 6. Control disk 9, passage disk 6, and bottom part 20 together form a disk package. Stem arms 25 of valve stem 3 engage in control disk 9, so that control disk 9 can be rotated on passage disk 6 by rotating valve stem 3 about axis of rotation 4. Control disk 9 is thus rotatable relative to passage disk 6. Passages 7, 8 (not visible here) in control disk 9 can be released by rotating control disk 9. In the mounted state of valve cartridge 1, a liquid can laterally run into an inlet chamber 26. Inlet chamber 26 is formed between cartridge housing 2 and control disk 9. If at least one of the passages 7, 8 formed in passage disk 6 is released by control disk 9, the liquid can flow through the respective passages 7, 8 parallel to longitudinal axis 19 in the direction of a valve seat 27 formed on an underside of bottom part 20.
[0037] FIG. 2 shows a detailed view of valve cartridge 1 in a perspective illustration in the region of passage disk 6. Control disk 9, disposed rotatably on passage disk 6, is shown as transparent here. Bottom part 20 and passage disk 6 are circular. Control disk 9 is also circular, wherein it has an opening 15 in the form of a cutout shaped as an annular segment. Opening 15 is here rotated in a first sector 12 of passage disc 6, in which no passage 7, 8 is formed. First passage 7 formed in a second sector 13 of passage disk 6 and second passage 8 formed in a third sector 14 are here concealed by control disk 9, so that no liquid can flow out of inlet chamber 26, shown in FIG. 1, through passages 7, 8. Valve cartridge 1 is thus closed in the shown rotational position of control disk 9.
[0038] FIG. 3 shows passage disk 6 in a perspective view. The passage disk has in its center a stem opening 28 through which the stem extends in the mounted state of passage disk 6. Furthermore, passage disk 6 has on its upper side 29 two recesses 30 in which stem arms 25, shown in FIG. 1, engage. Upper side 29 of passage disk 6 is subdivided into a first sector 12, a second sector 13, and a third sector 14 (shown using dashed lines). Sectors 12, 13, 14 are formed in the manner of circular sectors (of equal size) and/or each have a central angle 31 of 120. First passage 7 is located in second sector 13 and second passage 8 in third sector 14. Passages 7, 8 are each formed arc-shaped and extend parallel to axis of rotation 4 completely through passage disk 6. Furthermore, passages 7, 8 have a noise-reducing geometry in the form of a sawtooth profile at their inflow edges. In addition, passage disk 6 is formed mirror-symmetrical.
[0039] FIG. 4 shows valve cartridge 1 with mounted handle 5 in a longitudinal section. Valve cartridge 1 is mounted here on a support plate 32. A handle adapter 10, via which handle 5 is connected nonrotatably to stem 3, is attached to valve stem 3. Valve cartridge 1 is thus operable by a user by rotating handle 5 about axis of rotation 4. Handle 5 is in a closed position 16 here in which valve cartridge 1 is closed. In closed position 16 there is a radially outwardly extending handle element 33 at a 0 position or 12 o'clock position. Furthermore, the valve cartridge comprises a stop element 17 in the manner of a stop ring by which an angle of rotation of handle 5, stem 3, and control disk 9 is limited.
[0040] FIG. 5 shows handle adapter 10 in a perspective view. Along axis of rotation 4, handle adapter 10 has a sleeve-shaped section 34, with which handle adapter 10 can be attached nonrotatably to valve stem 3. Further, handle adapter 10 can be locked to valve stem 3. At one longitudinal end, the handle adapter has a flange section 35 which extends from sleeve-shaped section 34 in a radial direction 36 (perpendicular to axis of rotation 4). On its circumferential surface 37, flange section 35 can have a toothing 38 via which handle adapter 10 can be connected nonrotatably to handle 5. Handle adapter 10 has a first groove 40 and a second groove 41 at an inner diameter 39. First groove 40 and second groove 41 extend in inner diameter 39 parallel to axis of rotation 4. Further, first groove 40 and second groove 41 are arranged about axis of rotation 4 offset by 120 to one another. First groove 40 is at a 6 o'clock position here and second groove 41 at a 2 o'clock position.
[0041] FIG. 6 shows valve cartridge 1 of FIG. 4 in a front view. Handle adapter 10 is here attached to valve stem 3 in a first position 11. In first position 11, a rib 42 of valve stem 3, said rib extending parallel to axis of rotation 4 (which runs perpendicular to the plane of the drawing), engages in first groove 40 of handle adapter 10. This determines a first rotational orientation of valve stem 3 to handle 5. Rib 42 is formed on an outer surface 43 of valve stem 3. Handle adapter 10 can be connected to valve stem 3 in a second position. For this purpose, handle adapter 10 is released by valve stem 3 and placed on valve stem 3 such that rib 42 engages in second groove 41 instead of in first groove 40. For this purpose, valve stem 3 must be rotated by 120 to handle adapter 10. Valve stem 3 is then in a second rotational orientation to handle 5. Compared with first position 11, in the second position of handle adapter 10, valve stem 3 is rotated by 120 to handle adapter 10 and to handle 5 about axis of rotation 4.
[0042] FIGS. 7 to 12 show different positions of control disk 9 with respect to passage disk 6 as a function of the positions of handle adapter 10 and the angle of rotation of handle 5. Passage disk 6 and control disk 9 are each shown in a plan view. FIGS. 7 and 8 show passage disk 6 and control disk 9 in a first configuration of valve cartridge 1, in which handle adapter 10 is attached to valve stem 3 in first position 11 (cf. FIG. 6). In FIG. 7, handle 5 is in closed position 16, which may be a 0 position and/or 12 o'clock position. Opening 15 of control disk 9 is rotated into first sector 12 of passage disk 6, a sector in which there is no passage 7, 8. Valve cartridge 1 is closed thereby. FIG. 8 shows a position of control disk 9 after control disk 9 has been rotated counterclockwise by 120 with handle 5 and valve stem 3. Opening 15 of control disk 9 is now in second sector 13 of passage disk 6, so that first passage 7 is released. A liquid can thus flow away through passage 7. In the first configuration of valve cartridge 1, valve cartridge 1 has the stop element 17 shown in FIG. 13, by which an angle of rotation 18 of handle 5 is limited to 120. For this purpose, stop element 17 has a first stop 44 and a second stop 45 for handle 5. Control disk 9 can be moved thereby from the closed position shown in FIG. 7 only by 120 counterclockwise into the release position of first passage 7 shown in FIG. 8. In the first configuration, valve cartridge 1 is therefore designed in the manner of a (right-closing) upper part with which the flow of liquid of only one sanitary fitting can be controlled.
[0043] FIG. 9 shows a second configuration of valve cartridge 1, which differs from the first configuration only by stop member 17 shown in FIG. 14. Stop element 17 shown in FIG. 14 limits the angle of rotation 18 of handle 5 to 240. In the second configuration, control disk 9 can be moved not only into the closed position shown in FIG. 7 and into the release position of first passage 7 as shown in FIG. 8, but additionally from the closed position shown in FIG. 7 clockwise by 120 into the release position of second passage 8 as shown in FIG. 9. In this position, opening 15 of control disk 9 is located in the region of third sector 14 of passage disk 6, the sector in which second passage 8 is located. As a result, the liquid can flow away via second passage 8. In the second configuration, valve cartridge 1 is therefore designed in the manner of an Aquadimmer, with which the flow of liquid of two sanitary fittings can be controlled.
[0044] FIG. 10 shows a third configuration of valve cartridge 1, which differs from the first and second configurations only by stop element 17 shown in FIG. 15. Stop element 17 shown in FIG. 15 limits the angle of rotation 18 of handle 5 to 360. For this purpose, stop element 17 in the embodiment shown in FIG. 15 only has a first stop 44 for handle 5, which is designed here like a trailing stop. As a result, control disk 9 can be rotated from the closed position shown in FIG. 7 not only into the positions shown in FIGS. 8 and 9, but additionally into the position shown in FIG. 10. Here, control disk 9 was rotated from the position shown in FIG. 7 (closed position 16 of handle 5) by 180 clockwise or counterclockwise, so that opening 15 of control disk 9 is located partially in second sector 13 and third sector 14 of passage disk 6. As a result, both first passage 7 and second passage 8 are at least partially releasable (simultaneously). In the third configuration, valve cartridge 1 is therefore also designed in the manner of an Aquadimmer, with which the flow of liquid of two sanitary fittings can be controlled, wherein here the flow of liquid can be activated simultaneously for both sanitary fittings.
[0045] FIG. 11 shows a fourth configuration of valve cartridge 1, which differs from the first configuration only in that handle adapter 10 is attached to valve stem 3 in the second position. In FIG. 11, handle 5 is in the closed position 16, which can be the 0 position and/or 12 o'clock position. Because handle adapter 10 is attached to valve stem 3 in the second position, opening 15 of control disk 9 is in the closed position 16 of handle 5 in the region of second sector 13 of passage disk 6, so that first passage 7 is released. In order to prevent the liquid from flowing out through first passage 7 in the closed position 16 of handle 5, first passage 7 and/or a liquid channel adjoining first passage 7 are closed in a liquid-tight manner by a closing element, for example, in the manner of a stopper. In the fourth configuration of valve cartridge 1, it has stop element 17 shown in FIG. 13, which limits the angle of rotation of handle 5 to 120. FIG. 12 shows control disk 9 after it has been rotated counterclockwise by handle 5 and valve stem 3 by a 120 rotation. As a result, opening 15 of control disk 9 is located in third sector 14 of passage disk 6, so that second passage 8 is released. As a result, the liquid can flow off via the second passage. In the fourth configuration, valve cartridge 1 is also formed in the manner of a (right-closing) upper part, with which the liquid plus only one sanitary fitting can be controlled.
[0046] Differently configured valve cartridges with the same fitting housings or the same housing inserts can be employed using the present invention.
[0047] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
