    摘要: A master brake cylinder (2) communicates with wheel brakes through brake conduits (8, 9). Pumps (20, 21) deliver fluid to the brake conduits (8, 9) through pressure conduits (22, 23). Upon commencement of an anti-lock control, the pump drive M is turned on and check valve (26) in the brake conduit is blocked. In conventional systems, the check valve could, during a control operation, open upon an increased pressure fluid requirement of the wheel brakes. Use of a diaphragm in the pressure conduit (22) insures that the dynamic pressure in the chamber (37) will hold the switch piston (28) in all circumstances in a displaced position so that the valve ball (45) blocks the valve passage (46), and the brake conduit (8) is interrupted.
