ABSTRACT:
In a braking system a dump valve opens during an imminent skid condition to dump fluid from a brake circuit to a reservoir space. A reservoir piston defining a boundary of the reservoir space then moves in a first bore against a spring so that a control rod, integral with the reservoir piston, allows a ball valve member to engage with its seat to cut-off communication between a master cylinder and a wheel brake. Simultaneously, fluid flows from the reservoir space through an inlet valve to a working chamber of a pump provided in a second bore in the reservoir piston so that a pump piston working in the bore engages with a rotatable eccentric. Fluid is then pumped from the pump chamber, past an outlet valve through an outlet passage in the control rod, and returned to the reservoir space through the open dump valve.
