ANTI-SKID DEVICE FOR HYDRAULIC BRAKE MECHANISMS

摘要

A hydraulic braking system has a master cylinder with two pistons linked by a spring and separating the cylinder into two working chambers, one of which is connected via a distributor valve to the brake cylinders and the other of which is connected in a pump circuit which directly feeds one control port of the distributor valve and feeds indirectly, via an anti-skid control valve, a second control port of the distributor valve. The braking circuit is arranged to provide anti-skid braking and also to operate at least some of the brakes even in the event of a pump failure or a rupture in the pump circuit.
