Abstract
Description
Claims (2)
- 실린더 하우징(cylinder housing)과, 상기 실린더 하우징 내에 미끄럼 이동이 자유롭게 수납된 피스톤을 가지며, 상기 피스톤에 의해 상기 실린더 하우징 내에 복수의 압력실이 나뉘어 형성되는 액추에이터(actuator)를 구비하며, 상기 복수의 압력실에 연결되는 복수의 실린더측 통로를 형성하고, 상기 복수의 압력실에 대하여 상기 복수의 실린더측 통로를 통하여 압축공기의 공급 및 배출이 선택적으로 이루어지는 것에 의해 변속기의 변속작동을 행하는 변속이 조작장치에 있어서,상기 복수의 압력실에 연결되는 상기 복수의 실린더측 통로에 대기로부터의 유입을 저지하는 체크밸브를 설치하고, 상기 체크밸브를 통하여 상기 압력실의 공급된 압축공기를 대기에 배출하는 것을 특징으로 하는 변속기 조작장치.
- 제1항에 있어서,상기 복수의 압력실에는 압축공기의 공급 및 배출 이외에 대기의 흡입도 이루어지는 급배흡 압력실(給排吸壓力室)을 구비하며, 상기 급배흡 압력실에 연결되는 압축공기의 배출과 대기의 흡입을 행하는 흡입배출 통로에 교축부(絞縮部)를 형성한 것을 특징으로 하는 변속기 조작장치.
