摘要： This invention is to provide a brake system and a brake device for use of automobiles, in which a braking energy stored in an auxiliary pressure source can be exploited effectively for a braking purpose, even if an electrical system fails. In particular, the vehicle brake system includes a proportional pressure control valve 80 for generating braking liquid pressure by adjusting the braking energy stored in the auxiliary pressure source 30. Also the vehicle brake system comprises a passage 75 transmitting the liquid pressure generated by a stroke of a brake pedal 1, a switching valve 76 opening the passage in the powered condition and closing the same in the off-powered condition, and an auxiliary control portion 81 activating the proportional pressure control valve 80. Even in the off-powered condition, the high pressure accumulated in the auxiliary pressure source 30 can be used to adjust the required braking liquid pressure at the proportional pressure control valve 80. The switching valve 76 cane be replaces with a relief valve 116 and a return valve 117 for activating the proportional pressure control valve 80 so as to effectively utilize the high pressure of the auxiliary pressure source 30 even in the on-powered condition.

摘要： A hydraulic pressure control device is provided in which a proportional pressure control valve is actuated by operating the brake pedal to adjust the hydraulic pressure supplied from a pressure source to the wheel brakes to a value corresponding to the pedal operating amount. Also, a brake device for a vehicle using it is provided. The proportional pressure control valve is integrated with a hydraulic pressure generator to transmit the input from the brake pedal to a spool valve in the control valve through a first piston, first spring, second piston and second spring of the hydraulic pressure generator. If the pressure source or the wheel brakes in a first line fail, after the second piston has made a full stroke, brake fluid in a fluid chamber is pressurized, so that the hydraulic pressure generated is supplied to wheel brakes in a second line through a copy valve which is open.

摘要： A hydraulic pressure control device is proposed in which using a proportional pressure control valve having a built-in spool valve, the hydraulic pressure for wheel brakes is adjusted to a value corresponding to the magnitude of an external force applied to the spool valve, non-electrical pressure adjustment can be done both in a normal state and in an emergency, and the structure is simplified. The brake pedal is coupled through a spring to the spool valve of the proportional pressure control valve having a solenoid for generating a spool-driving force, and the brake pedal force is applied to the spool valve as an external force so that not only in an emergency but in a normal state, pressure is adjusted by the brake pedal force.

摘要： An antilocking brake fluid pressure control unit for a vehicle includes a fluid pressure control device which receives an antilocking operation signal for controlling the pressure applied to a wheel brake. A pump in a parallel flow circuit returns a brake working fluid. A damping chamber (13) is connected to a fluid passage (9) between an outlet port of the pump and a feedback point (15). A filter is provided in the fluid passage (9) between the damping chamber (13) and the feedback point (15). Due to this structure, air bleeding from a brake piping system is simplified when assembling the brake system in a vehicle, and the time needed for charging a working fluid into the brake system is reduced.
