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 time rate at which pressure increases in a friction element (96, 74, 98) engaged to produce a gear shift is controlled through operation of an accumulator (256, 260, 262). Shift valves (232, 236) in a hydraulic circuit produce selectively a connection between hydraulic lines associated with the friction elements to be engaged and a source of line pressure. A first control pressure has a magnitude that varies according to a required torque transmitting capacity of the friction element. A line modulator valve (220) produces a second control pressure having a magnitude that varies with the magnitude of the first control pressure but at a different rate. An accumulator includes a piston movable within a cylinder defining a first volume connected to the second control pressure output by the line modulator valve, and a first volume communicating with line pressure. The accumulator control valve directs this pressure to the second volume of the accumulator through an orifice having a predetermined diameter that controls the flow rate of fluid into the second volume of the accumulator. When line pressure is removed from the accumulator control valve to disengage the friction element, the clutch or brake is vented through the shift valve.

摘要： The stroking order of the band brake servo piston (130) and the accumulator piston (114) are reversed under high and low transmission loads, therefore reversing the pressure modifying effects provided by the same. This is achieved by selecting the various areas and springs which determined the resistance against which the piston must stroke under high and low load conditions (wherein the level of the line pressure changes), and the forces which drive the pistons against the resistances.
摘要翻译：带式制动器伺服活塞（130）和蓄能器活塞（114）的行程顺序在高和低传动载荷下相反，因此扭转了由其提供的压力修正效果。这通过选择确定在高负荷条件下（其中管线压力变化的水平）活塞必须行进的阻力的各种区域和弹簧以及驱动活塞抵抗电阻的力来实现。

摘要： A control system for a four speed ratio automatic transmission wherein a ratio change from a first speed ratio to a second speed ratio is effected by a 1-2 shift valve (118) that activates a fluid pressure operated second ratio clutch (CL₂) and a ratio change from a third speed ratio to a fourth speed ratio is effected by a 3-4 shift valve (122) that activates a fluid pressure operated fourth ratio brake (B₁), both the clutch and the brake having an independent pressure accumulator (642 resp. 664) and an accumulator pressure regulator valve (126) that is common to both accumulators for developing unique accumulator control pressures whereby the system may be calibrated for maxium shift smoothness for both 1-2 upshifts and 3-4 upshifts.
