Clutch release cover device for lid-fixed central releaser, has air bubble guide element which engages to piston projection arranged in pressure chamber, such that cross-section of pressure chamber is reduced in region of supply hole

摘要

The clutch release cover device has housing (2) which is provided with an annular pressure chamber (3), in which a movable piston (4) is supported axially. A supply hole (5) is formed in an outer wall (2.1) of the housing, in which a clutch is arranged. An air bubble guide element (10) is engaged with a piston projection (9) arranged in the pressure chamber, which is connected with a ventilation system (7), such that cross-section of the pressure chamber is reduced in the region of the supply hole, by engagement of air bubble guide element.
