Abstract: In a power take-off a spring engages a hydraulically actuated clutch-activating pressure plate to force the same into a neutral position. In one embodiment of the invention a hydraulically operated spring-loaded piston for arresting the rotational motion of an output shaft engages the pressure plate upon shifting thereof into its neutral position and consequent uncoupling of the output shaft from an input or drive shaft. In another embodiment of the invention an annular friction disk slidably connected or splined to the output shaft for stopping the same is clamped between a brake housing and a hydraulically actuated piston. The pistons automatically retract under the action of respective springs upon shut-off of the vehicle engine driving the input shaft and energizing the hydraulic system actuating the plates and the pistons, whereby the angular position of the output shaft may be manually adjusted.

Abstract: A fluid pressure control system for controlling an automatic transmission which includes a gear transmission mechanism and several fluid pressure actuated friction engaging mechanisms, selective engagement of which provides various speed stages from the gear transmission mechanism. A line pressure valve produces a line pressure which increases from a base pressure by an amount proportional to engine load. A throttle pressure valve produces a throttle pressure which is proportional to engine load. A shift valve selectively switches supply of an actuating pressure to one of the friction engaging mechanisms via a passage, according to the operational condition of the vehicle. The actuating pressure is supplied by a fluid pressure control system which receives supply of line pressure and which outputs a pressure which, when engine load is medium, is approximately equal to line pressure, but which, when engine load is small or is large, is substantially lower than line pressure.
