Abstract
PURPOSE: To promptly and surely perform the snap actionlike selecting operation of a switching valve for selecting a directly coupled clutch to a state of engagement and disengagement in an automatic speed change gear having a torque converter with the directly coupled clutch.
CONSTITUTION: An automatic speed change gear having a torque converter 1 with directly coupled clutch 50 between an engine crank shaft 8 and turbine shaft 9 comprises an oil pressure source including an oil pump 101, speed selecting valve 210, shift valves 220 and 230 and a throttle valve 240. While a switching valve 60, for selecting the communication of the oil pressure source to directly coupled clutch disengaging and engaging oil lines 87 and 89, and a lock-up control valve 70, for operating said valve 60, are provided. At this time the switching valve 60 is provided with a spool valve 65, for performing selecting operation between oil chambers 67 and 68 normally communicated with the oil lines 87 and 89 and clutch disengaging and engaging oil lines 103 and 90 from the lock-up control valve 70, and constituted in such a manner as to press said spool downward by a spring 61.
