A damper for use in a hydraulic clutch actuator to attenuate vibrations transmitted from the crankshaft of the engine of the associated vehicle to the clutch pedal. The baffle includes an elongated cylindrical housing positioned in the conduit interconnecting the master and slave cylinders of the actuator coaxial with the axis of the conduit and including a spring biased piston mounted in the bore of the housing. The housing is open at its rear end and closed at its front end by an end wall defining an outlet port for the damper and the piston includes a central through passage defining the inlet port of the damper at the rear end of the through passage. A baffle is provided at the front end of the piston to provide a circuitous path between the central passage of the piston and the outlet port of the damper. The front face of the baffle includes a hemispherical surface which deflects attenuations entering the housing from the slave cylinder and routes the attenuations through the circuitous path defined by the baffle.

Damper for hydraulic clutch actuator

A baffle is provided at the front end of the piston to provide a circuitous path between the central passage of the piston and the outlet port of the damper. In an alternate embodiment, the damper further includes the male half of a quick connect coupling so as to facilitate the use of the damper in a clutch actuator of the type including separate prefilled modules which are connected by the quick coupler following installation of the separate modules.
