Abstract
A water pump for an internal combustion engine having a pump casing and a pump cover that forms a circulation cavity. A plate is positioned interface of the pump casing and the pump cover and divides the circulation cavity into an inlet passage and an outlet passage and has a seal portion that seals against the leakage between the inlet passage and the outlet passage of a gap of the interface of the pump casing and the pump cover.
Claims15
A water pump for an internal combustion engine comprising:
- a pump casing, having a recess and a first interface;
- a pump cover, having a recess and a second interface adapted for matching to said first interface of said casing;
- a circulation cavity being formed by said recesses of said pump casing and said pump cover;
- a plate positioned at a portion of said interface and dividing said circulation cavity into an inlet passage and an outlet passage;
- and
- a fluid seal, formed integrally as part of said plate, wherein said fluid seal is a bent part of said plate that is sloped.
