Hydraulic slave cylinder esp. for clutches has piston with hollow-cylindrical wall and piston head and end with cut-outs to define head and end sectors

摘要

The slave cylinder has a stationary part (9) and a hollow-cylindrical piston (11), forming a variable volume chamber (13) in the part. The piston has a piston head (41), with long axial cut-out recesses (42). These are formed to define evenly distributed head sectors (43). A piston end (51) has similar cut-outs to define end sectors (53). Cut-outs in head and end are offset relative to each other.
