VEHICLE HYDRAULIC ACTUATING SYSTEM

摘要

VEHICLE HYDRAULIC ACTUATING SYSTEM A master-slave hydraulic control system preferably for actuating a vehicle clutch utilizes single-acting hydraulic cylinders which are both connected to a fluid reservoir. The higher mounted cylinder has a bleed valve in the line connecting that cylinder with the fluid reservoir. The lower mounted cylinder is connected to the fluid reservoir via a check valve. The check valve allows fluid communication between the reservoir and the lower cylinder when the pressure within that cylinder is below a predetermined value. The hydraulic system may be bled regardless of the position of extension of either cylinder.
