Hydraulic actuating device for manually operating, servo-supported motor vehicle clutch, has clutch pedal interacting with master cylinder and slave cylinder stays in active connection with clutch release organ of clutch

摘要

The hydraulic actuating device (10) has a clutch pedal (30) interacting with a master cylinder (16) and a slave cylinder (20) stays in active connection with the clutch release organ of the clutch. A pressure line (26) is provided to connect both cylinders. A servo device (40) is arranged in the flow path between the two cylinders for generating a servo force active with a servo pump (42) in the slave cylinder. An inlet (42a) and an outlet (42b) of the servo pump stays in fluidic connection through a static orifice (44), with the master cylinder and the slave cylinder respectively.
