Device for ventilating hydraulic passage leading from pressure source to actuator of dual clutch transmission of motor car, has vent valve comprising spring for applying force to valve member such that fluid is pushed against valve seat

摘要

The device has a vent valve (8) comprising an inlet opening (24) that is in fluidic connection with a hydraulic passage (3). A conduit section (9) comprises a valve member (10) i.e. shut-off piston, and two cone-shaped valve seats (11, 12). The valve member is moved between two positions, where hydraulic fluid i.e. oil, is applied into the valve seats in the positions. The vent valve comprises a helical compression spring (15) for applying force to the valve member such that the hydraulic fluid is pushed into the conduit section against one of the valve seats.
