摘要： PURPOSE:To reduce consumption in a hydraulic fluid, by making a selector valve intercept a balancing chamber from a feeding chamber and simultaneously interconnecting it to an output chamber in time of brake commanding, while making the selector valve interconnect the balancing chamber to the feeding chamber and simultaneously intercepting it from the output chamber in time of brake releasing. CONSTITUTION:When control pressure AS goes up, a feeding chamber 1 is interconnected to an output chamber 2 and a balancing chamber 4 whereby output pressure goes up. And, when the control pressure goes down, the output chamber 2 is interconnected to an exhaust chamber 6 whereby the output pressure goes down. Thus, the output pressure proportioned to the control pressure AS in response to car load is securable. Here a selector valve 30 is excited in time of release commanding and selected to a first position 31, causing the feeding chamber 1 to be interconnected to the balancing chamber 4, while it intercepts the output chamber 2 and the balancing chamber 4 either. And, the selector valve is magnetized in time of brake commanding, and selected to a second position 32, intercepting the feeding chamber 1 and the balancing chamber 4, while it interconnects the output chamber 2 to the balancing chamber 4.

摘要： PURPOSE:To prevent an increase in sliding resistance at a sliding surface between a valve and a valve seat by separating and removing graphite component at the upper surface portion of the valve seat to form a lot of vary small vertical concave portions, and accumulating lubricating oil in the concave portion. CONSTITUTION:A raw material cast iron is subjected to necessary machining, such as boring a supply and discharge hole 4 and the first outlet 3. Just after the surface portion of the machined valve seat 2 is heated up to about 850 deg. by a burner, the surface portion is dipped in quenching oil to be rapidly cooled. The quenching and tempering will cause the surface portion of the valve seat to fall off graphite, and increase hardness of the portion. After the flatness of the surface portion is increased, lapping is performed. At the time of lapping, graphite is removed to form concave portions. The concave portion 20 has a diameter of several mu and a depth of several tens of mu, and lubricating oil is accumulated in the concave portions 20.

摘要： PURPOSE:To reducce moving of chassis due to braking when backing by performing pressure reduction control of front wheel side brake when backing, while never reducing the pressure of the same when advancing. CONSTITUTION:Upon stepping of brake pedal under advancing, the liquid pressure in master cylinder is fed through a contact hole 10, a chamber 77, a hole 29 in main piston, a stepped hole 30 in axial direction, a hole 28 and a connection hole 11 to the wheel cylinder of front wheel thus to function the front wheel brake. Said liquid pressure is also transmitted through a path 52, a valve system 76, a through-hole 45 of control piston and a path 53 into the control pressure chamber 27. Consequently, main piston 20 will never move even upon pressure rise, thus to never execute pressure reduction control. While when backing, coil 37 is excited to close the valve system 76. Since the liquid pressure in master cylinder is never fed into the control pressure chamber 27, main piston 20 will move to the left upon pressure rise in master cylinder, thus to execute pressure reduction control.
摘要翻译：目的：通过在背面执行前轮侧制动器的减压控制时，通过制动来减少制动时的底盘移动，同时在前进时不会降低压力。构成：在制动踏板前进时，主缸中的液压通过接触孔10，室77，主活塞中的孔29，轴向的阶梯孔30，孔28和连接孔 11到前轮的轮缸，从而起到前轮制动的作用。所述液体压力也通过路径52，阀门系统76，控制活塞的通孔45和路径53传递到控制压力室27.因此，即使在压力升高时主活塞20也不会移动，从不执行减压控制。当背衬时，线圈37被激励以关闭阀系统76.由于主缸中的液体压力不会被馈送到控制压力室27中，所以主活塞20将在主缸中的压力升高时向左移动，从而执行减压控制。

摘要： PURPOSE:To reduce the stepping force of a pedal, by energizing the pedal in direction of reducing its stepping force by means of an assist piston which operates itself upon receiving delivery pressure at the delivery port of a valve body in time of pedal stepping on. CONSTITUTION:When a brake pedal 13 is stepped on, a piston 25 is set in motion and an exhaust valve seat 38 takes its place to a valve member 34 and afterward, the valve member 34 comes off a feed valve seat 39. And, compressed air in a first input chamber 36 flows into the inside of a first control pressure chamber 27 and further the compressed air flows into one side of brake actuators by way of a first output port and simultaneously flows into a relay chamber 45. At this time, the compressed air in the control pressure chamber 27 also flows into the inside of a pressure air chamber of a stepping force reducing device 20 by way of a pipe 87 whereby an assist piston 82 is driven toward the upper part against a spring 84. Therefore, the pedal 13 receives turning force in the stepping direction via a roller 18, thus stepping force is reduced. In addition, with the compressed air in the relay chamber 45, a piston 47 is operated so that the other side brake system is set in motion in an interlocking manner.
