Abstract

PURPOSE:To prevent shifting of a piston by providing the third solenoid valve for opening fluid pressure supply lines of the first and second solenoid valves to a tank, thereby to open fluid pressure supply lines to the tank. CONSTITUTION:When a solenoid valve 6 is on, and a solenoid valve 2 is ON, oil pressure is supplied to the left chamber 1c of a cylinder 1, so that a piston 16 is moved to the right to shift a shift lever 8 to the gear first speed side. The shifting is detected by a position switch 9, and a signal is sent to an electronic control device 10. When the solenoid valve 6 is ON, and the solenoid valve 3 is ON, the shift lever is reversely shifted to the gear backward side. Accordingly, it is possible to overcome the disadvantage caused by lag in timing when two solenoid valves 2, 3 are OFF.

Even if the two solenoid valves receive a command to turn off at exactly the same time, the timing itself cannot be controlled because the solenoid valves are switched mechanically.If there is a difference in the switching timing of the two solenoid valves 2 and 3, It may happen that the piston moves to either the 3'' or 1' force plane. Then, the performance of the electromagnetic valve 2.3 deteriorates and the drive circuit deteriorates, causing similar problems. For this reason, for example, in the case of transmission shift and select control, there is a risk that problems such as select position shift and neutral position shift may occur.
