摘要： A hydraulic pressure control valve for use with two independent rear braking systems, for transmitting braking hydraulic pressure to wheel cylinders in two rear wheels of a vehicle through two independent pipings. The control valve has a pair of valves, a pair of parallel pistons disposed in a single housing, and an actuating mechanism for displacing the pistons according to vehicle load. The actuating mechanism consists of a lever capable of rocking in a plane, a spring member for applying a force corresponding to the vehicle load to the rocking end of the lever, a support pin having both ends fitted in two grooves that extend parallel to the axes of the pistons and are equidistant from these axes, an equalizer which comes into abutment with one end of each piston at its either end. The equalizer is supported on the pin such that it can rock about its recessed center.

摘要： A brake fluid pressure controller is interposed between a master cylinder and the rear wheel cylinders. The controller comprises a housing having an inlet, an outlet and a chamber which provides communication between the inlet and the outlet. An annular sealing member is disposed around a piston in the chamber with a clearance left therebetween. The sealing member has an inner perimeter defining a valve seat and an outer perimeter defining a flexible lip portion which is in contact with the internal wall of the chamber. When a valve head of the piston sits on the valve seat of the sealing member, the inner perimeter of the valve seat cuts off the communication between the inlet and the outlet. Meanwhile, the outer perimeter permits a communication from the outlet to the inlet but shuts off a communication from the inlet to the outlet. A spring urges the piston to a direction in which the valve head separates from the valve seat. A regulating member contacts the inner perimeter of the sealing member in the chamber from a side opposite to the valve head. The regulating member regulates the sealing member from moving in a direction from the valve head toward the regulating member.

摘要翻译： 制动液压控制器介于主缸和后轮缸之间。 控制器包括具有入口，出口和室的壳体，其提供入口和出口之间的连通。 环形密封构件设置在腔室中的活塞周围，其间留有间隙。 密封构件具有限定阀座的内周边和限定与腔室的内壁接触的柔性唇部的外周边。 当活塞的阀头位于密封构件的阀座上时，阀座的内周切断入口和出口之间的连通。 同时，外周边允许从出口到入口的连通，但是切断从入口到出口的连通。 弹簧将活塞推向阀头与阀座分离的方向。 调节构件从与阀头相对的一侧接触腔室中的密封构件的内周。 调节构件调节密封构件沿从阀头朝调节构件的方向移动。

摘要： A brake pressure control unit of vehicle load responsive type is disposed in a brake pressure line extending from a master cylinder to wheel brake cylinders and composed of a P-valve, a load-sensing lever abutting on a plunger of the P-valve, a secondary spring disposed between the bracket secured to the P-valve and the free end of the lever, and a primary spring disposed between the other free end of the lever and a lower end of a rod which is swingably held on the other free end of the lever. The brake pressure control unit is preassembled as one unit before it is installed in the vehicle as it is. The direction of the biasing force of the secondary spring is the same as that of the primary spring.
