Claims (5)

  1. 유압유체를 수용하는 실린더와, 실린더안에서 작동되며 이를 제1 및 제2실로 분할하는 피스톤과, 피스톤에 고정되어 제1실을 통해서 실린더의 외부까지 연장된 피스톤로드와, 댐퍼의 팽창 및 수촉행정시 제동력을 발생시키도록 피스톤상에 설치한 제동력 발생밸브장치로 구성된 유압댐퍼에 있어서, 피스톤상에 상기 밸브장치를 우회하는 상기 두 실을 연결하기 위한 측로통로와, 댐퍼의 수촉행정과 팽창행정사이의 상기 측로통로안의 유체유동을 변화시키기 위한 역지밸브로 구성된 것을 특징으로 하는 유압댐퍼.
  2. 제1항에 있어서, 상기 측로통로가 피스톤로드안에 각각 형성된 동심의 구멍과 방사상의 구멍으로 구성된 것을 특징으로 하는 유압댐퍼.
  3. 제1항에 있어서, 상기 측로통로의 유효면적을 조절하기 위한 밸브를 마련하고, 상기 밸브를 상기 구멍을 통해 연장된 작동로드에 고정되고 댐버의 외부에서 작동될 수 있는 것을 특징으로 하는 유압댐퍼.
  4. 제2항에 있어서, 상기 역지밸브를 피스톤로드안의 상기 방사상의 구멍을 보통 밀폐하기 위해 제1실에 마련하고 상기 밸브는 댐퍼의 수축행정시 열리는 것을 특징으로 하는 유압댐퍼.
  5. 제2항에 있어서, 상기 역지밸브가 보통 제2실의 유체압력을 받으며 댐퍼의 수축행정시에 열리는 것을 특징으로 하는 유압댐퍼.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
