Claims (3)
- 유체작동형 토크 렌치에 있어서, 이 유체작동형 토크 렌치가 축선을 갖는 실린더와 구동부를 갖춘 실린더부분, 서로 독립되어 상기 축선을 따라서 이동가능하며 피스턴 롯드를 갖는 두개의 피스턴, 상기 구동부에 배치된 두개의 래치트-레바기구, 상기 래치트-레바기구가 연결된 구동요소와, 상기 실린더에 유체를 공급하기 위한 유체공급수단을 가지고, 상기 피스턴은 유체가 축방향에서 보아 일측 피스턴의 일측부와 타측 피스턴의 타측부에서 상기 유체공급수단에 의하여 공급될 때 상기 일측 피스턴이 일측 래치트-레바기구가 래치트될 수 있도록 일측 축방향으로 이동하는 반면에 상기 타측 피스턴은 상기 구동요소를 회전시키기 위하여 타측 래치트-레바기구를 회전토록 다른 축방향으로 이동하며, 유체가 축방향에서 보아 일측 피스턴의 타측부와 타측 피스턴의 일측부에서 동시에 상기 유체공급수단에 의하여 공급될 때 상기 일측 피스턴이 상기 구동요소를 회전시키기 위하여 일측 래치트-레바기구를 회전토록 상기 다른 축방향으로 이동하는 반면에 상기 타측 피스턴은 일측 래치트-레바기구가 래치트될 수 있도록 상기 일측 축방향으로 이동함을 특징으로 하는 유체작동형 토크 렌치.
- 제1항에 있어서, 상기 피스턴중의 하나가 중공형이고 제1롯드가 연결되는 중공형 피스턴 롯드를 가지며, 상기 피스턴중의 다른 하나가 상기 중공형 피스턴 롯드내로 연장되고 제2롯드단부를 갖는 솔리드형의 피스턴 롯드를 가지고, 상기 롯드단부가 상기 래치트-레바기구의 대응하는 것에 연결됨을 특징으로 하는 유체작동형 토크 렌치.
- 제2항에 있어서, 상기 피스턴이 상기 타측부에서 동일한 피스턴영역을 가질 수 있도록 상기 타측 피스턴이 상기 솔리드형 피스턴 롯드와 동일한 직경을 갖는 제2의 피스턴 롯드를 가짐을 특징으로 하는 유체작동형 토크 렌치.
