    • A control system for an automatic transmission includes a first frictional engagement element and a second frictional engagement element; and a first hydraulic servo for controlling the application/release of the first frictional engagement element and a second hydraulic servo for controlling the application/release of the second frictional engagement element. A regulator valve regulates the oil pressure to the first hydraulic servo. A signal pressure is applied to the regulator valve to establish a predetermined gear stage by switching the applied/released states of the first frictional engagement element and the second frictional engagement element by feeding/releasing oil pressure to/from the first hydraulic servo and the second hydraulic servo. The regulator valve includes a valve member having: a first pressure receiving area to which is applied the feed pressure to the first hydraulic servo as a feedback pressure in a first direction; a second pressure receiving area to which is applied the signal pressure in a second direction opposite the first direction; a fourth pressure receiving area to which is applied the feed pressure to the second hydraulic servo in the first direction, in a shift wherein the first frictional engagement element is released while the second frictional-engagement element is applied; and a third pressure receiving area to which is applied the signal pressure in the second direction, for regulation of the oil pressure only during a shift.

    • Two solenoid-actuated shuttle valves selectively direct hydraulic fluid from a line pressure source to a clutch and brake servo or direct fluid from the clutch and servo to a low pressure drain, in accordance with the combined states of the solenoids. The system includes several orifices, which in combination control the rate of flow between the pressure source and the friction elements. The orifices control also the flow rate in the system between the friction elements and drain ports. Accumulators are located in the system between the shuttle valves and the friction elements. An arrangement of check valves and orifices located between the shuttle valves and the accumulators establish the rate of flow between each of the accumulators and the associated friction element.
    • 根据螺线管的组合状态,两个电磁致动梭阀选择性地将液压流体从管路压力源引导到离合器,并将制动器伺服或直接流体从离合器和伺服转换到低压排放管。 该系统包括几个孔,其组合地控制压力源和摩擦元件之间的流速。 孔也控制系统中摩擦元件和排出口之间的流量。 蓄能器位于梭阀和摩擦元件之间的系统中。 位于梭阀和蓄能器之间的止回阀和孔口的布置确定了每个蓄能器和相关联的摩擦元件之间的流量。
