Method for operating of hydraulic clutch in motor vehicle is such that piston of master cylinder in unloaded position of clutch is pushed into pressure chamber into standby position far enough for snifting orifice to be closed

摘要

The method is for the operating of a hydraulic system for the operating of a clutch of a motor vehicle with a master cylinder (4) with an axially movable piston (17) defining a fluid filled pressure chamber (18) and which in snifting position opens a connection between a snifting orifice (20) and the pressure chamber. The piston in the unloaded position of the clutch is pushed into the pressure chamber into a standby position far enough for the snifting orifice to be closed, and a pressure greater than atmospheric is built up in the hydraulic system.
