Abstract:

A cooling pump receives fluid from a heating system and supplies cooled fluid to an engine. The cooling pump includes a body housing and a cover housing. The cover housing is attached to the body housing to define an internal pumping chamber. The internal pumping chamber is defined between an inlet passage and an outlet passage of the body housing. A chamber outlet opening is defined between the internal pumping chamber and the outlet passage such that fluid flows from the internal pumping chamber and into the outlet passage. The cover housing includes a sloped wall which extends into the outlet passage between the chamber outlet opening and a terminus. The sloped wall has a concave portion and a convex portion disposed such that the concave portion is between the chamber outlet opening and the convex portion to direct fluid through the outlet passage and into the engine.
