(40) The fluid line extends through the housing 19 and exits the housing 19 on the downstream side in the flow direction 11 of the gas-carrying line 2 and enters the interior 39 of the gas-carrying line 2.

(41) The gas-carrying line 2 carries the compressed air 3 that is pressurized as shown in FIG. 1.

(42) Downstream in the flow direction 11 of the gas-carrying line 2, a connecting flange 10 connects to the gas-carrying line 2 and to the fluid line 5 running in the interior 39 thereof.

(43) The connecting flange 10 is supported (not shown in FIG. 2) on the gas-carrying line 2 by a bearing, preferably a ball bearing, radially rotatable relative to the longitudinal axis 12 thereof.

(44) The connecting flange 10 is thereby sealed off on one side thereof relative to the gas-carrying line 2 and on the other side thereof relative to an outlet device 4, such that no compressed air 3 can escape outward into the interior of the spout-shaped tube profile 15.

(45) Downstream in the flow direction 11 of the compressed air 3, the connecting flange 10 opens into the outlet device 4.

(46) The fluid line 5 transporting the fluid 6 extends in the interior of the outlet device 4.

(47) The compressed air 3 is fed in the interior of the gas-carrying line 2 in the direction toward an opening 13 of the outlet device 4 and thereby flows around the outer wall of the fluid line 5.

(48) As is shown in FIG. 2, the outlet device 4 comprises at least two bends 45.

(49) When the connecting flange 10 rotates according to an arrow direction 46, the outlet device 4 also rotates about the longitudinal axis 12 of the connecting flange 10 in the arrow direction 47.

(50) The opening 13 of the outlet device 4 faces outward eccentrically relative to the longitudinal axis 12 in the direction of an arrow 48 due to the bends 45 made in the outlet device 4.

(52) Due to the eccentric alignment of the opening 13 of the outlet device 4, swirling 49 of the mixture 14 of compressed air and fluid arises in the interior of the spout-shaped tube profile 15.

(53) The swirling 49 of the mixture 14 of compressed air ad fluid is applied along the longitudinal axis 12 of the connecting flange 10 in the direction toward an object 50 to be cleaned.

(54) A valve switch 23 of a valve 8; 9, not shown, is depicted in plan view in FIG. 2 on the bottom of the housing 19.

(55) FIG. 3 shows the housing 19 of the system 1 for outputting the mixture. In FIG. 3, the valve switches 22 and 25 and/or the compressed air valve 8 and the fluid valve 9 are each disposed offset from each other.

(56) A valve switch 22 for compressed air 3 and a valve switch 25 for controlling the fluid flow 6 are shown on the top side of the housing 19.

(57) The housing 19 of the system 1 for cleaning objects is penetrated by the gas-carrying line 2, in the interior 39 of which the fluid line 5 runs.

(58) The housing 19 is pivotally supported on the pivot axis 21 of the switch lever 20.

(59) The switch lever 20 is shown in section view in FIG. 3. A flat contact surface 24 is depicted on the bottom of the switch lever 20 in the plan view of FIG. 3.

(60) By pivoting the switch lever 20 about the pivot axis 21, the contact surface 24 of the switch lever 20 makes contact with the valve switches 22; 25.

(61) If the user (not shown) pivots the switch lever 20 further in the direction of an arrow 51, then the contact surface 24 of the switch lever 20 presses against the valve switch 22 of the compressed air valve 8 and simultaneously the contact surface 24 of the switch lever 20 also presses down the valve switch 25 of the fluid valve 9 when the switch lever 20 is pivoted further in the direction of the arrow 51.

(62) By actuating the valve switches 22 and 25, the compressed air valve 8 and the fluid valve 9 are opened or closed.

(63) FIG. 4 shows the housing 19 of the system 1 for outputting the mixture according to FIG. 3, with the difference that the pivot bearings 52 are shown on which the switch lever 20 (not shown) are supported pivotally about the pivot axis 21.

(64) The housing 19 according to FIG. 4 differs from the housing according to FIG. 3 in that the valve switch 22 of the compressed air valve 8 is mounted on the top side of the housing 19 in the depiction of FIG. 4. The valve switch 25 of the fluid valve 9 is, in contrast, mounted on the side of the housing 19 of the system 1 for outputting the mixture.

(65) The depiction in FIG. 5 differs from the depiction in FIG. 4 in that the valve switch 22 of the compressed air valve 8 and the valve switch 25 of the fluid valve 9 are each disposed in different planes 53; 54 having a different distance from the longitudinal axis 12 of the connecting flange 10 (not shown).

(66) FIG. 6 corresponds approximately to the depiction of FIG. 3, with the difference that the switch lever 20 in the schematic depiction of FIG. 6 is disposed having the pivot axis 21 thereof at the top side of the housing 19, wherein the pivot axis 21 extends approximately parallel to the longitudinal axis 12 of the connecting flange 10 (not shown).

(67) The switch lever 20 is depicted as penetrated in FIG. 6.

(68) The switch lever 20 thereby comprises a greater material thickness in the region of the valve switch 22 of the compressed air valve 8 than in the region of the valve switch 25 of the fluid valve 9.

(69) In addition, the valve switch 22 and the valve switch 25 are disposed transversely relative to the longitudinal axis 12 of the connecting flange 10 (not shown), contrary to the depiction in FIG. 3.

(70) By pivoting the switch lever 20 in the arrow direction 51, the switch lever 20 actuates the valve switch 22 of the compressed air valve 8 first, due to the different material thickness of the switch lever 20. Only by pivoting the switch lever 20 further in the arrow direction 51 does the switch lever 20 make contact with the valve switches 25 of the fluid valve 9.

(71) FIG. 7 correspond to the depiction in FIG. 6 with respect to the arrangement of the valve switches 22 and 25, with the difference that the pivot axis 21 of the switch lever 20 extends transverse to the longitudinal axis 12 of the connecting flange 10 (not shown).

(72) The switch lever 20 is shown in cutaway in the depiction in FIG. 7.

(73) The contact surface 24 of the switch lever 20 comprises a pedestal 55 on the bottom side of the switch lever 20.

(74) In the region of the pedestal 55, the contact surface 24 of the switch lever 20 makes contact first with the valve switch 22 of the compressed air valve 8 when pivoting the switch lever 20 in the arrow direction 51.

(75) Only by pivoting the switch lever 20 further in the arrow direction 51 does the contact surface 24 of the switch lever 20 also make contact with the valve switch 25 of the fluid valve 9.

(76) The depiction in FIG. 8 corresponds to the depiction in FIG. 7, with the difference that two separate switch levers 56; 57 are provided.

(77) The switch lever 56 actuates the compressed air valve 8, while the switch lever 57 controls the fluid valve 9.

(78) The switch lever 57 is implemented so as to overlap the switch lever 56.

(79) When pressing down the switch lever 57 in the arrow direction 50, the switch lever 57 pushes the switch lever 56 along, so that the fluid valve 9 can only be actuated when the compressed air valve 8 is actuated simultaneously.

(80) A tongue 58 of the switch lever 56 of the compressed air valve 8 reaches under the switch lever 57 of the fluid valve 9.

(81) Because of this design, the compressed air valve 8 can be actuated separately and individually, independently of the fluid valve 9.

(82) The fluid valve 9, in contrast, can only be actuated and opened together with the compressed air valve 8. In this manner, it is ensured that the fluid, preferably the cleaning agent, can be applied to the object 50 to be cleaned only in the form of a mixture of compressed air and fluid.

(83) FIG. 9 corresponds to FIG. 8, with the difference that the schematic depiction in FIG. 9 shows two switch levers 56; 57 that can be actuated individually and independently of each other.

(84) FIG. 10 shows a gas-carrying line 2 comprising a segment 68 comprising the outlet device 4. Said segment 68 is separated from the other, upstream segment 69 of the gas-carrying line 2.

(85) The segment 68 of the gas-carrying line 2 comprising the outlet device 4 is displaceable in the axial direction against the other, upstream segment 69 of the gas-carrying line 2. The spacing between end faces facing each other of the other, upstream segment 69 of the gas-carrying line and the segment 68 of the gas-carrying line 2 comprising the outlet device 4 can be axially changed.

(86) The other, upstream segment 69 and the segment 68 comprising the outlet device 4 are designed for connecting axially to each other in a gas-tight manner by means of a connecting flange 10.

(87) The end faces of the two segments 68; 69 of the gas-carrying line 2 facing each other protrude into the connecting flange 10. The segment 68 of the gas-carrying line 2 comprising the outlet device 4 is disposed in the interior of the connecting flange 10 for displacing relative to the other segment 69 of the gas-carrying line 2 in a gas-tight manner. For sealing the segment 68 comprising the outlet device 4 against the connecting flange 10, a sealing means can be disposed on the inner wall of the connecting flange 10.

(88) The fluid line 5 comprising no interruptions extends in the interior of the gas-carrying line 2. The fluid line 5 bridges the end faces of the segments 68 and 69 of the gas-carrying line in the interior of the connecting flange 10.

(89) The segments 68; 69 running in the interior of the connecting flange 10 and the fluid line 5 are shown as dashed lines.

(90) FIG. 10 further shows that the outlet device 4 comprises a body 59 for mechanically cleaning the surface 50.

(91) The body 59 is implemented as a brush. The body 59 can also be a sponge or a wire construct for mechanically cleaning. The body 59 can also be a different element for mechanically cleaning a surface 50.

(92) The body 59 is disposed on the outlet device 4.

(93) The outlet device 4 comprises a segment 60 extending along the longitudinal axis 12 of the gas-carrying line 2. The body 59 for cleaning the surface 50 is disposed on the segment 60 of the outlet device 4 extending along the longitudinal axis 12 of the gas-carrying line 2.

(94) The end 66 of the body 59 for cleaning the surface 50 downstream in the axial direction does not protrude beyond the downstream end 67 of the outlet device 4.

(95) The outlet device 4 further comprises a further segment 61 connected to the segment 60 extending along the longitudinal axis 12 of the gas-carrying line 2 and extending eccentric to the longitudinal axis 12 of the gas-carrying line 2.

(96) The body 59 for cleaning the surface 50 (not shown) can also be disposed at the end 62 of the further segment 61 connected downstream and running eccentric to the longitudinal axis 12 of the gas-carrying line 2.

(97) The outlet device 4 is connected to the connecting flange 10. A rotation of the connecting flange 4 brings about a rotation of the outlet device 4. The rotation of the outlet device 4 brings about rotation with the outlet device 4 of the body 59 disposed on the outlet device 4 for cleaning the surface 50. The body 59 for cleaning the surface 50 rotates in the interior of an enclosure 63 radially enclosing the outlet device 4.

(98) An adapter (not shown) is disposed at the end 64 of the enclosure 63. The enclosure 63 is implemented as an enclosing tube profile.

(99) The enclosure 63 is radially rotatable relative to the housing 19 (not shown). Conversely, the housing 19 (not shown) can be disposed radially rotatably relative to the enclosure 63.

(100) The arrangement of the body 59 for mechanically cleaning the surface 50 has been found to be advantageous because the cleaning of the surface 50 by means of a mixture 14 of gas and fluid can be supported in this manner by mechanically cleaning by means of a body 59 for mechanically cleaning the surface 50.
