  • Patent number: 4922120
    Abstract: A slip-controlled hydraulic brake system with improved operational reliability during the slip control phase of operation has a master cylinder having shortened overall axial length. The master cylinder includes a valve-opening mechanism of one central control valve supported on the bottom of the longitudinal bore of the master cylinder, and the valve-opening mechanism of another central control valve supported on the secondary piston wherein during a slip control action, in the presence of a predetermined travel of the pistons of the master cylinder, a force component is generated that increases the reliability of the opening of the central control valves.

  • Patent number: 4900101
    Abstract: A brake system with slip control is disclosed including a master cylinder to which wheel brakes are connected through controllable main valves. An auxiliary-pressure supply system including a hydraulic pump, a regulating and pressure-monitoring valve and a pressure-compensating and pressure-fluid supply reservoir is connected to the wheel brakes through electromagnetically actuatable inlet and outlet valves. The outlet valves are normally closed in their inactive condition with each one pair of wheel brakes communicating directly with one inlet valve and one outlet valve. Wheel sensors and an electronic circuitry determine the wheel rotational behavior and generate electric braking-pressure control signals for operating the inlet and outlet valves. The inlet valves are closed in their inactive condition and are switched to open upon actuation and have their inlet side directly connected with the auxiliary-pressure supply system and their outlet side directly connected with the main valves.

  • Patent number: 4891945
    Abstract: The brake pressure generator (1) includes a tandem master cylinder (2) actuable by two booster pistons (19, 32) to which a hydraulic auxiliary pressure is applied and by a pedal actuating mechanism (17,18). A control valve (14, 20) controls the auxiliary boost pressure. The control valve, through an actuator (16), cooperates with the pedal actuating mechanism (17,18). One booster piston (32) is disposed on the bottom of the tandem master cylinder (2) adjacent the push rod (22). Normally-open valve (37) closes when brake pressure exceeds boost pressure to trap fluid in chamber (34).
