摘要： In a hydraulic braking pressure control system for a rear wheel brake wherein a control piston normally works to provide a hydraulic braking pressure control by cooperation with a cut-off valve interposed between an input chamber leading to a master cylinder and an output chamber leading to a wheel cylinder of the brake, the cut-off valve has a valve seat piston whose pressure-receiving area facing the output chamber is larger than the pressure-receiving area facing the output chamber. This ensures that opening and closing of the cut-off valve can be repeated in accordance with the output pressure from the master cylinder, so that the output pressure from the master cylinder can be reduced and applied to the brake wheel cylinder. When the control hydraulic pressure is lost, the control piston and sleeve can be moved in a direction to increase the volume of the output chamber thereby to close the lock valve and tightly close a control chamber between the control piston and sleeve, while restraining by a stopper the movement of the cut-off valve following in a closing direction of the control piston and sleeve. This makes it possible to insure a hydraulic braking pressure applied to the brake wheel cylinder.

摘要： A hydraulic braking pressure control system which includes a sleeve slidably received in a housing with opposite ends facing an output chamber connected to a brake device, and a pilot chamber connected to a control hydraulic pressure source. A control piston is slidably received in the sleeve, with one end of the control piston facing the output chamber and the other end facing a control chamber connected to the control hydraulic pressure source through a lock valve which is adapted to be closed in response to the movement of the sleeve, in a direction to increase the volume of the output chamber. A cut-off valve located between an input chamber leading to a master cylinder and the output chamber includes a valve member having a maximum amount of movement in a seating direction which is regulated to a position of the valve member spaced apart from a valve seat when a valve seat member follows movement of the sleeve in a direction to reduce the volume of the pilot chamber to the maximum amount. This ensures that the opening of the cut-off valve and tight closing of the control chamber upon an abnormal reduction of the control hydraulic pressure from the control hydraulic pressure reduction source can be achieved with a simplified system.

摘要： A pressure device control apparatus including a pressure source having a pump, and an accumulator connected to the pump and a pressure device, and a pressure detector for detecting the pressure in the accumulator; a normally-closed type solenoid valve interposed between the pressure device and the accumulator or a fluid tank; and a control unit having a drive control device for outputting a driving signal indicative of a command to operate the pump in response to a detection pressure detected in the pressure detector becoming equal to or less than a first predetermined pressure and a drive stopping signal indicative of a command for stopping the operation of the pump in response to the detection pressure becoming equal to or more than a second predetermined pressure which is higher than the first predetermined pressure. The control unit includes a first energizing unit for energizing the normally-closed type solenoid valve for a first predetermined time after the drive control device outputs the drive stopping signal, and a deciding unit for deciding that there is a problem in response to the detection pressure detected in the pressure detector becoming equal to or less than the first predetermined pressure after the energization of the normally-closed type solenoid valve by the first energizing unit is completed. This invention ensures that the diagnosis of the problem in the pressure device control apparatus can be reliably effected by the release of the pressure in the accumulator after the pressure increase thereof to a level equal to or more than the second predetermined pressure.
