Abstract

An anti-locking hydraulic brake system is described which includes a pump, the output of which flows through a pressure valve (20), a damping chamber (24), a check valve (28) and a throttle (3I) and is delivered to a pressure connection in communication with the wheel brake conduit. To ensure, in a compact structural design, a noise-minimizing hydraulic pressure source, while avoiding a flow back of pressure fluid from the brake system into the damping device, a check valve (28) is integrated into the damping device. A pressure valve is integrated with the check valve and damping chamber, with an elastomeric elastic member disposed in the damping chamber to absorb pressure pulsations.
