摘要： A system for controlling a lock-up clutch comprises a lock-up control valve including a spool and a plug in a spool bore. The spool is movable between a lock-up clutch engagement position and a lock-up clutch disengagement position. The plug is axially movably inserted at one end of the spool bore, and has a pressure acting area whose diameter is larger than the maximal diameter of the spool. This pressure acting area is subject to a pressure when the transmission establishes the first or reverse speed. Thus, in the event the transmission establishes the first or reverse speed, the spool is displaced to the lock-up clutch disengagement position by a force applied to the pressure acting area of the plug.

摘要： A hydraulic pressure control system for a transmission comprises a pressure reduction valve which regulates fluid supply to an output hydraulic fluid line from an input hydraulic fluid line and fluid discharge from the output hydraulic fluid line to a drain hydraulic fluid line. In order to assure an inflow of hydraulic fluid to the output hydraulic fluid line, there is provided an orifice connected between the input hydraulic fluid line and the output hydraulic fluid line. A relief valve is provided at the drain hydraulic fluid line to restrain discharge of hydraulic fluid from the drain hydraulic fluid line. Thus even if the pressure reduction valve is sticked, there remains hydraulic fluid pressure in the output hydraulic fluid line.

摘要： The feedback chamber of the pilot pressure valve is supplied with its discharge after it has been filtered whereby the pressure which is supplied to the feedback chamber is subject to the flow restricting effect of the strainer and increases the valve output to compensate for the flow restrictive nature of the strainer.

摘要： Accurate location of a switch body is assured by providing a switch lever and a lever which operates the switch lever, with alignment apertures the centers of which describe arcs which intersect at only one or two positions and which allow the levers to locked together via the insertion of a probe until a third aperture, provided in the switch body, can be aligned with the first and second ones.
