Abstract:
A hydraulic clutch actuator system including a master cylinder, a slave cylinder, and a damper between the master cylinder and the slave cylinder, the damper including a housing, including port means for connecting in the system and an imperforate diaphragm carried by the housing beneath the port means and forming a boundary for the system so that the diaphragm may deflect in response to vibrations transmitted through the hydraulic fluid in the system to effect damping of the vibrations, characterized in that:the housing has a canister configuration and includes a thin imperforate annular sidewall above the diaphragm of substantially uniform thickness and coacting with the diaphragm to define a large volume fluid chamber above the diaphragm providing further system damping by virtue of vibratory volumetric expansion of the annular sidewall.
