Motor-Vehicle Brake System with Anti-Lock Control

摘要

A motor-vehicle brake system with anti-lock control has a pneumatic tandem brake booster (29) which acts on a master cylinder (11). The control valve (33) of the brake booster (29) is arranged laterally of the input rod (36) which is loaded by the brake pedal (30). A change-valve arrangement (47,47') is applied to the vacuum space (1) and to the pressure space (2) of the rear pneumatic piston (46) and is loaded by a control circuit (28) responding to the wheel slip, in such a way that a pressure equalisation takes place temporarily between the respective spaces in the event of wheel slip. <IMAGE>
