摘要： An oil pressure controller of an automatic transmission which is capable of supplying engaging pressures to hydraulic servos of two frictional engaging elements which require different engaging pressures by a single pressure governing valve with a good pressure governing accuracy. The oil pressure controller comprises a hydraulic power source 10, hydraulic servos 70 and 80, signal pressure generating means 20, a pressure governing valve 30 for governing an oil pressure (Ps) from the hydraulic power source 10 by a signal pressure (PACC) and a control valve 40. The pressure governing valve 30 has a pressure receiving face A1 to which the signal pressure is applied, a pressure receiving face A2 to which the engaging pressure (Ps) is fed back in the opposite direction and a pressure receiving face A3 for selecting whether the feedback of the engaging pressure is present or not in order to change the control gain of the pressure governing valve 30 in response to the change of the control valve 40 for selecting the hydraulic servo 70 or 80 to which the oil pressure is supplied.

摘要： A hydraulic control system for an automatic transmission comprising: a frictional engagement element (B-3); a hydraulic servo (28) for controlling the application/release of the frictional engagement element (B-3); an oil passage (201) connected to the hydraulic servo (28) for feeding/releasing an oil pressure to the hydraulic servo (28); a pressure regulator valve (25) disposed in the oil passage; and signal pressure generating means (SLU;...) for applying a signal pressure to the pressure regulator valve (25). The oil passage (201) includes: a first oil passage (201d) for feeding the oil pressure to the pressure regulator valve (25); and a second oil passage (201e) for feeding the oil pressure from the pressure regulator valve (25) to the hydraulic servo (28). The pressure regulator valve (25) includes: a valve member (250); an input port (254) connected to the first oil passage (201d); an output port (255) connected to the second oil passage (201e); and a drain port (257) connected to a drain oil passage (EX). The valve member (250) has: a first pressure receiving area (A₁) to be fed with the feedback pressure of the second oil passage (201e) in a direction to provide the communication between the output port (255) and the drain port (257); a second pressure receiving area (A₂) to be fed with the signal pressure (P SLU ) in a direction to provide the communication the output port (255) and the drain port (257); and a third pressure receiving area (A₃) having an area different from that of the second pressure receiving area (A₂). The signal pressure generating means (SLU;...) feeds the signal pressure to the third pressure receiving area (A₃) at all times and the signal pressure (P SLU ) selectively to the second pressure receiving area (A₂).

摘要： The gearbox has one or more rotating sections surrounded by a housing at the base of which is an oil sump. Oil capture units (51-54,61-64) are located on each side (36a) of the rotating sections, removing excess oil from the rotating sections within the gearbox, and returns this to the oil sump.

摘要： PROBLEM TO BE SOLVED: To restrict a pulsation of output hydraulic pressure of a pressure adjusting valve at normal and high oil temperatures while a responsiveness to a control signal pressure of the pressure adjusting valve at a low oil temperature in a system for directly controlling a supplying pressure for a hydraulic servo in an automatic transmission. SOLUTION: A hydraulic control device comprises a hydraulic servo 28 for engaging with and releasing a frictional engaging element B-3, a pressure adjusting valve 25 for directly adjusting a hydraulic pressure supplied to the hydraulic servo 28 without any accumulator, and a signal hydraulic oil passage 203 for applying a pressure adjusting signal pressure to the pressure adjusting valve 25. The signal hydraulic oil passage 203 is provided with a control valve 24 for setting a degree of opening of the oil passage to a predetermined degree of opening at normal and high oil temperatures and increasing it more than the predetermined degree of opening at a low oil temperature.
