摘要： A water pump for an internal combustion engine includes a body, a driving shaft held rotatably in the body, an impeller fixed on the driving shaft, a volute chamber formed in the body and including a deflecting portion adapted for introducing a coolant to an outlet port, a chamber formed in the body on a back side of the impeller and including an inner circumferential portion and an outer circumferential portion, and at least two ribs disposed so as to connect the inner circumferential portion and the outer circumferential portion of the chamber, one of the ribs disposed adjacent to the deflecting portion of the volute chamber, whereby inibiting foreign matters contained in the coolant from being left in a space formed between the inner circumferential portion and the outer cicumferential portion of the chamber. When foreign matters are contained in the coolant and when the foreign matters intrude into the chamber, the foreign matters collide with the ribs. The ribs immediately evacuate the foreign matters back to either the volute chamber or the outlet port by way of an outlet passage. Thus, the foreign matters are not kept to circulate in the chamber, and accordingly the erosion of the body can be inhibited from happening.
