Abstract
In a control valve assembly of the kind set forth for vehicle braking systesm a valve-operating member for operating first and second valves is guided to slide in a bore in a piston. The valve-operating member is adapted to permit the second valve to close and the first valve subsequently to open when the first piston is returned to an inoperative retracted position in response to the pressure of fluid remaining the pressure space when the applying force is relieved, the pressure space being defined between the first piston and a second piston.
