Wheel brake controller with antilock pressure variation decoupling - has constriction in one brake line between junctions with other line and with return from reservoir

摘要

The master cylinder (10) coupled to the brake pedal (B) has a forward storage chamber (10a) in the brake fluid circuit (20). An antilock protection circuit (30) connected downstream (P2) from the constriction (O) in one brake line (21) includes a reservoir (33), a pump (34) and a pulsation damper (35). - Magnetically actuated three/two-way valves (31,32) in the respective brake lines (21,22) are controlled (37) in response to signals from wheel tachometers (15,16).
