Car clutch hydraulic actuator operational readiness preparation unit, has hydraulic pistons with valve controlled fluid link impedance and flow

摘要

A car clutch hydraulic actuator operational readiness preparation unit has two hydraulic pistons (14, 16) with fluid link (24) through a valve (25) controlled (26) to limit the volume flow through the piston to the output system (5) inter piston (16) region to a set threshold value with hydraulic impedance controlled by valves (32, 33).
