The slave cylinder is integrated into the bearing flange.

Claims (14)

1 - 9 . (canceled)

10 . A clutch-actuating unit for a motor vehicle clutch with a hydraulic release apparatus, comprising:

a slave cylinder having a working chamber disposed concentrically to a transmission input shaft;

an axially movable ring piston disposed in the slave cylinder; and

a bearing flange receiving and supporting the slave cylinder,

wherein the slave cylinder is integrated in the bearing flange.

11 . The clutch-actuating unit according to claim 10 , wherein the slave cylinder is formed with the bearing flange as one piece.

12 . The clutch-actuating unit according to claim 11 , further comprising a working chamber and a flow channel, the flow channel activates the slave cylinder in the bearing flange that extends radially outside towards the working chamber.

13 . The clutch-actuating unit according to claim 12 , wherein the flow channel is formed through a bore or through several meeting bores.

14 . The clutch-actuating unit according to claim 12 , wherein the flow channel is formed from radially outside through at least a main bore and two adjoining transverse bores.

15 . The clutch-actuating unit according to claim 14 , further comprising permanent, high-pressure resistant sealing elements, wherein the transverse bores having bore entry holes are sealed with the permanent, high-pressure resistant sealing elements.

16 . The clutch-actuating unit according to claim 10 , further comprising an external connection pressure line, wherein the bearing flange has a hydraulic connection for the external connection pressure line on a radial external end, and whereby the hydraulic connection is a screwable connection coupling and is screwed from a radial outside position into the bearing flange.

17 . The clutch-actuating unit according to claim 10 , wherein the ring piston has running surfaces and the running surfaces are separately treated.

18 . The clutch-actuating unit according to claim 10 , wherein the bearing flange is one piece.
