摘要

In a motor vehicle an anti-locking braking device associated with the wheel brakes and including supply fluid under pressure connectible to the brake cylinders through a three-way valve which is controlled by a known device for detecting abnormal deceleration of the wheels. The valve is interposed between the supply, the brake cylinders and exhaust and can be operated to connect the suuply to the brake cylinders or the brake cylinders to exhaust. In the exhaust path there is provided a flow-limiter which may be merely a restriction orofice and a damper interposed in the exhaust path between the controlled three-way valve and the flow-limiter. The damper may simply be a piston and cylinder device in communication with the exhaust path, the piston being balanced by the exhausting fluid pressure and a spring.
