摘要： A fluid pressure booster device includes a booster body, a control piston in the booster body for forward and rearward movements to define a boosting chamber between the control piston and a rear surface of a master piston of a master cylinder, a valve piston in the control piston for forward and rearward movements and communicating at its front face with the boosting chamber, a reaction piston in the control piston for forward and rearward movements and connected to an operating member, the reaction piston defining a reaction chamber between itself and a rear face of the valve piston, a stroke accumulator having an accumulation chamber connected to the reaction chamber, an inlet valve disposed between the control piston and the valve piston and interposed in a flow passage extending between the boosting chamber and a fluid pressure source, the inlet valve being closed when the valve piston is retracted and opening when the valve piston advances, and an outlet valve disposed between the control piston and the valve piston so as to open when the valve piston is retracted and to be closed when the valve piston advances. This enables a fluid pressure to be applied to the master cylinder in response to the motion of the operating member within a restricted stroke range.

摘要： A hydraulic booster for a master cylinder in which an inlet valve is interposed between an output pressure chamber at the back of the booster piston and an input pressure chamber connected to a pressure source. Advance of the valve piston opens the inlet valve. An outlet valve between the output chamber and an outlet chamber connected to an oil tank closes at advance of the valve piston relative to the booster piston. The booster chamber is exposed to a rear of a master cylinder operation piston. The valve piston oil feed passage connects input pressure chamber with booster chamber at opening of the outlet valve. The reaction chamber at the front surface of the booster piston is reduced in volume with the advancing movement and is connected to an accumulator making it possible to smooth initial operation of the master cylinder and reduce booster system size.

摘要： A hydraulic braking pressure control system for a vehicle comprises a master cylinder (M) operatively connected to a brake pedal (P), an operation-amount detector (S) for detecting the amount by which the brake pedal is operated, a hydraulic pressure control unit (2.sub.FL etc.) for controlling the hydraulic pressure to be applied to a brake device (B.sub.FL etc.) mounted on a wheel in accordance with an applied quantity of electricity, and a control circuit (3) for controlling the quantity of electricity to be applied to the hydraulic pressure control unit, in accordance with a detection value provided by the operation-amount detector. The system further includes a cut-off valve (30.sub.FL etc.) adapted to be closed in response to depression of the brake pedal, and a reservoir (R.sub.2) connected through the cut-off valve to an oil passage (27) connecting the hydraulic pressure control unit and the brake device. The cut-off valve is opened when the brake pedal is not depressed, and even if a hydraulic pressure is delivered from the hydraulic pressure control unit when there is no braking operation, such hydraulic pressure can be released into the reservoir, ensuring that any such hydraulic pressure is prevented from being applied to the brake device.

摘要： A hydraulic braking pressure control system includes a shut-off valve (4) which is provided in an oil passage (58) connecting a brake device with an output port in a master cylinder and which is brought into a closed state by a control circuit when a braking operation is detected by an operation-amount detector, and a locking device (5) for inhibiting the closing of the shut-off valve when the output hydraulic pressure from a hydraulic pressure supply source in equal to or less than a predetermined value. The shut-off valve is opened when there is no braking operation, thereby ensuring that even if a hydraulic pressure is delivered from a hydraulic pressure control valve when there is no braking operation, such hydraulic pressure can be released into a reservoir. In addition, if the hydraulic pressure in the hydraulic pressure supply source is abnormally reduced, that shut-off valve is locked in its opened state by the locking device to ensure that the output hydraulic pressure from the master cylinder can be applied to the brake device.

摘要： A turning motion control system for a vehicle includes an actuator, and an actuator control device for controlling the actuator so that an actual turning motion state of the vehicle becomes close to a target turning motion state. The actuator control device is designed so that its control-permitted state and its control-stopped state can be switched from one to another through a switching device operated by a driver. When an air-pressure decreased state detecting device has detected an air-pressure decreased state, the actuator control device carries out the control of the operation of the actuator, irrespective of a switching mode of the switching device. Thus, even if an air-pressure decrease or an abnormality is generated in any of wheels in a state in which the turning motion control by the actuator has been stopped, the stability of the vehicle can be ensured.

摘要： A brake system for a vehicle includes a master cylinder for outputting a liquid pressure corresponding to a braking operation quantity, an electric actuator capable of outputting the liquid pressure corresponding to the braking operation quantity, and a switch-over valve capable of switching the connection and disconnection between the master cylinder and wheel brake. The electric actuator is connected to the wheel brake to block the back flow of a working liquid from the wheel brake. Braking pressure applied to the wheel brake is detected by pressure detector. When a difference between the detected braking pressure and a target braking pressure corresponding to the braking operation quantity exceeds a predetermined range, an output liquid pressure from the master cylinder is applied to the wheel brake. Thus, even if a trouble is produced in the electric actuator, itself, or a drive circuit for driving the electric actuators, the braking pressure for the wheel brake is prevented from being reduced undesirably.
