    摘要: A regulator valve is structured such that hydraulic pressure to be output from a regulated pressure output port is regulated according to urging forces, i.e., line pressure to be regulated, throttle pressure, spring force from a compression coil spring, and operating force from a plunger, which are applied to a valve spool. The plunger has a small diameter portion and a large diameter portion having a diameter larger than the diameter of the small diameter portion, both of which are axially displaceably retained in a spring receiving sleeve. The small diameter portion is urged in one axial direction at one end of the plunger that protrudes into a spring chamber and faces the valve spool, while the large diameter portion is urged in the other axial direction by range pressure at the other end of the plunger which is isolated from the small diameter portion located in the spring chamber.

    摘要: A hydraulic control system for an automatic transmission, which includes a brake, used to establish a first gear step and a reverse gear step. The hydraulic control system includes a first solenoid valve, a second solenoid valve and a control valve, which is switched by a hydraulic signal from the second solenoid valve, and that are operated simultaneously to engage the first-gear step and reverse gear step engagement element; and an neutral gear position engagement control unit that activates both solenoid valves when a shift lever is shifted to neutral to engage the brake. Thus, the generation of a shock may be prevented when the shift lever is shifted from the N position to an R position.
