Claims (5)

  1. 급수유로상에 배설되고, 수류가 발생하였을때 조리개부에서 압력강하시켜서 저압부를 발생시키는 벤류리부와, 내부의 실린더실을 연통구를 통해서 상기 벤튜리부의 조리개부에 연통시킨 실린더와, 이 실린더내에 접동 가능하게 감합된 피스톤과, 그리고 이 피스톤을 상기 실린더실의 연통구쪽을 향해서 부세하는 스프링을 가지고, 이 스프링은 상기 유로내에 수류가 생겼을때 피스톤을 실린더의 앞단부까지 밀어내고, 상기 유로내에 돌발적 압력상승이 발생하여 피스톤이 되밀렸을때, 실린더의 후단부에 당접하기 이전에 상기 피스톤을 정지하게 하는 크기의 스프링힘을 가지고 있는 것을 특징으로하는 수격완충장치.
  2. 제1항에 있어서, 상기 실린더중 피스톤을 사이에 두고 반대쪽의 공간부는 공기통로를 개재해서 대기에 통하고 있는 동시에, 이 공기통로에 실린더내를 향하는 공기흐름을 허용하고, 그것과 반대방향의 공기흐름을 저지하는 체크밸브가 배설되어 있는 것을 특징으로하는 수격완충장치.
  3. 내부의 실린더실을, 일단부쪽에 형성된 연통구를 통해서 급수관로에 연통 시키는 실린더와, 이 실린더에 접동가능하게 감합되고, 실린더실을 연통구쪽의 수실과 이 연통구와 차단된 공기실로 구획하는 피스톤과, 이 피스톤을 상기 연톤구쪽을 향해서 부세하는 스프링과, 상기 공기실내에 공기를 인도하는 공기도입로와, 그리고 이 공기도입로상에 배설되고, 외부로부터 이 공기실로의 공기의 유입을 허용하는 한편, 반대방향의 흐름르 저지하는 체크밸브를 가진 것을 특징으로하는 수격완충장치.
  4. 제2항에 있어서, 상기 피스톤에는 상기 스프링을 수납할수 있는 오목부가 형성되고, 이 오목부내에 피스톤이 최대로 이동하였을때 실린더내의 대향쪽에 고정설치된 체크밸브의 적어도 일부가 유삽될수 있도록 구성하여 이루어진 것을 특징으로 하는 수격완충장치.
  5. 제3항에 있어서, 상기 피스톤에는 상기 스프링을 수납할수 있는 오목부가 형성되고, 이 오목부내에 피스톤이 최대로 이동하였을때 실린더내의 대향쪽에 고정설치된 체크밸브의 적어도 일부가 유삽될수 있도록 구성하여 이루어진 것을 특징으로 하는 수격완충장치.
