Hydraulic master and slave system for clutch operation in motor vehicle engine

摘要

The system has several displacement units. One (3) of the units has a ventilation aperture (4), and is located lower than the another displacement unit (1). The hydraulic line (2) connecting the units is formed in steps. Each step has one section, which rises slightly in the direction of relief, and another section, connected to the top end, which falls slightly in the relief direction. The volume of the falling section is smaller than that of the rising section, and considerably smaller than the volume which is displaced during a master-sided displacement stroke.
