Abstract

PURPOSE: To make the pumping rate variable by controlling a gap between a vane and a conical surface mating with it in response to actuation of the means to sense off the water temperature for cooling an engine.
CONSTITUTION: When water temperature for cooling the engine is below a certain value, a seal 27 of a plate 24 contacts a conical surface 25 actuated by a water temperature sensing means 20, and the plate 24 shifts to the side nearer the pump impeller 18 driven by a moving part 21 which operates is accordance with temperature rise of the cooling water. When the water temperature has attained to a certain determined value, the moving part 21 moves upward to allow the seal 28 on the plate 24 to make contact with a conical surface 26. While the temperature is low, i.e. the gap between the face 22 of a vane 17 and the conical surface 23 mating with it is large, the pumping rate can be made small and, while this gap is small, i.e. the temperture is high, the rate can be made large.
