Abstract

압축형 유체 스프링 장치가 개시된다. 본 발명의 압축형 유체 스프링 장치는, 유체가 채워진 제1 챔버 및 제1 챔버와 구획된 제2 챔버가 마련된 베이스 바디; 제1 챔버의 일단부를 실링하는 제1 실링부; 제1 챔버의 타단부를 실링하며 제1 챔버와 제2 챔버를 구획시키는 제2 실링부; 및 제1 챔버에 배치되는 커넥터; 일측부는 커넥터에 연결되고 타측부는 제1 챔버의 외부로 돌출되는 제1 피스톤 로드; 및 일측부는 커넥터에 연결되고 타측부는 제2 실링부를 관통하여 제2 챔버에 배치되는 제2 피스톤 로드를 포함하고, 제2 챔버의 내부는 대기압으로 유지되고, 제1 피스톤 로드의 직경은 제2 피스톤 로드의 직경보다 작게 마련되는 것을 특징으로 한다.
