Abstract

댐핑력 제어형 유압완충기 내부에서, 피스톤은 주 유압유체통로 및 밸브기구를 구비하고, 그에 연결된 피스톤 로드를 또한 구비한다. 완충기 내부 실린더의 한 측면은, 바이패스통로를 개폐하는 셔터와 가이드부재를 구비한 댐핑력 제어기구와, 바이패스통로를 통해 유압유체의 유동을 통제함으로써 댐핑력을 발생시키는 밸브기구가 제공된다. 댐핑력 특성은 회전 액츄에이터를 구비한 셔터의 회전에 의해 변화된다. 댐핑력 제어기구는 실린더의 측면상에 마련되고 피스톤은 단지 주 유압유체통로와 밸브기구를 구비하기 때문에, 피스톤 조립체의 크기는 비교적 작다. 따라서, 피스톤로드의 스트로크는 증가될 수 있다.
