Patent

CA 2479461

A water jet pump is provided which reduces cavitation and thereby allows an improvement in pump efficiency. In a water jet pump in which an impeller driven to rotate is provided in a cylindrical housing, an R is attached to the edge portion of the outer circumferential surface of the impeller opposing the inner surface of the housing to reduce a variation in the pressure of a water stream passing between the outer circumferential surface of the impeller and the inner surface of the housing toward the impeller front surface side, thereby reducing the occurrence of cavitation and improving the pump efficiency.
