Abstract

PURPOSE: To make accurate the open time of the direct coupled clutch and the begining and end of the speed change operation by the method wherein, at the time of speed change in speed change steps, the direct coupled clutch is opened for a fixed time by means of an orifice or an accumulator valve and a lockup cutoff valve.
CONSTITUTION: Accumulator valve 410 consists of pressure accumulation oil chamber 411, spool 412 and spring 413. When oil pressure is drawn into oil chamber 411, spool 412 gradually moves downward as shown in the drawing, and after a fixed time, it connects oil chamber 325 of lockup cutoff valve 320 and oil path 141 via oil path 146. During the time when oil pressure is drawn in oil chamber 323 and oil chamber 325 of spool 321 of lockup cutoff valve 320, it lies upward by the action of spring 322. When oil pressure in oil chamber 323 rises from a value below a specified value to a value above a specified value, spool 321 moves downward, and this condition is maintained for a specified time determined by check valve 390 and pressure accumulation oil chamber 411.
