Abstract
PURPOSE: To smoothly control a direct-coupled clutch by controlling a lock-up shift valve operated by a sloenoid valve actuated by an electric circuit which receives signals from a pressure switch, and providing a manually operated switch to the electric circuit.
CONSTITUTION: A hydraulic controller of an automatic speed change gear including a direct-coupled clutch 50 of a torque convert is provided with a speed regulating valve 210 to which pressure oil is supplied by an oil pressure pump 101 through a pressure regulating valve 200, a first/second shifting valve 220 to which the line pressure is applied through an oil passage 104, and a governor valve 260. A second/ third shifting valve 230, a governor control valve 310, a throttle valve 240, overdrive shifting valve 270, and a lock-up shifting valve 300 are also provided. A solenoid valve 390 is connected to an oil passage 140 connecting to an oil passage 113 through the governor control valve 310. The solenoid valve 390 is controlled by an electric circuit 400 corresponding to the output signals of a pressure switch 600.
