Abstract
A first control valve which is normally open connects a master cylinder connection to a wheel cylinder connection. A second control valve which is normally closed connects the wheel cylinder connection to a storing chamber for returning brake fluid and to an inlet passage of a return pump when it is in open position. The return pump communicates through an output passage with a damping chamber. The damping chamber is arranged in a valve receptacle for the first control valve, and the storing compartment is arranged in a valve receptacle for the second control valve.
