Abstract

본 발명은, 냉각수가 유입 및 토출되는 유입구 및 토출구가 형성된 하우징과, 상기 하우징 내부에 수용되며 회전에 의해 냉각수를 유입 및 토출시키는 임펠러와, 상기 임펠러에 결합하며 외부 구동력을 전달받아 상기 임펠러를 회전시키는 회전축과, 상기 임펠러의 상측에 배치되며 상기 토출구를 선택적으로 개폐하도록 작동하는 냉각수유량제어수단을 포함하는 본체부; 상기 냉각수유량제어수단의 상측에 형성되어, 상기 냉각수유량제어수단에 압력을 가하는 냉각수를 수용하는 유압공간이 내부에 형성된 실린더부; 상기 유압공간 내부에 위치하며, 상기 유압공간 내부에 존재하는 냉각수에 압력을 가하는 피스톤; 상기 실린더부의 측면에 결합하며, 상기 피스톤을 전후진시키는 구동부; 및 상기 피스톤의 전면 또는 후면과 대향하는 상기 실린더부의 내측 면에 위치하며, 탄성 소재로 이루어지는 잠김방지부재를 포함하는 워터펌프를 제공한다.
본 발명에 따른 워터펌프에 의하면, 잠김방지부재를 구비함으로써, 피스톤이 실린더부의 내벽에 접촉되어 움직이지 못하는 상황을 원천적으로 방지할 수 있다.
