Abstract

본 발명은, 단시간으로 배기하는 것을 가능하게 하며, 변속기어를 동기 상태로 하여 맞물리게 할 때, 조작필링이 나쁘게 되는 것을 방지가능하게 하는 것을 목적으로 한다.An object of the present invention is to enable exhausting in a short time, and to prevent operation peeling from becoming bad when the transmission gears are engaged in a synchronous state.

상기 목적을 달성하기 위하여, 본 발명은, 실린더내를 2개의 압력실(7a)(7b)로 구획하는 피스톤(4)를 가지며 시프트 조작축의 입력레버에 연계시킨 중공(中空)의 출력로드(28)와 절환밸브(13)의 밸브몸체(24)(25)를 눌러 개방시키기 위한 밸리리프터(26)(27)와 그 밸브리프터의 외주에 끼워 맞추는 튜브(18)(19)를 구비하며, 배출유로의 도중에 있는 그 튜브의 내주에는 확경부(36)(37)을 가지며, 그 확경부와 밸브리프터(26)(27)의 외주와의 사이의 틈을 바이패스유로 (20)(21)로 하여, 작동시에 변속기어를 동기상태로 맞물림 한 직후의 부하감소에 맞게 고압측의 압력실에 바이패스유로를 연통시켜 그 고압측의 압력실에서 공기를 원할하게 배출시키는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a hollow output rod (28) having a piston (4) for dividing a cylinder into two pressure chambers (7a) (7b) and connected to an input lever of a shift operation shaft. And valve lifters 26 and 27 for pressing and opening the valve bodies 24 and 25 of the switching valve 13 and tubes 18 and 19 fitted to the outer circumference of the valve lifter. The inner circumference of the tube in the middle of the flow path has enlarged diameter portions 36 and 37, and a gap between the enlarged diameter portion and the outer circumference of the valve lifter 26 and 27 is transferred to the bypass flow passage 20 and 21. In this case, the bypass passage is connected to the pressure chamber on the high pressure side in order to reduce the load immediately after the transmission gear is engaged in a synchronous state, thereby smoothly discharging air from the pressure chamber on the high pressure side.
