US Patent:

51880652, Feb 23, 1993

Filed:

Mar 5, 1992

Appl. No.:

7/846574

Inventors:

Richard Lyndhurst - Costa Mesa CA
John D. Drake - Mission Viejo CA

International Classification:

F01P 510

US Classification:

123 4144

Abstract:

A water pump assembly for use on an internal combustion engine comprising a rotor assembly, including an impeller having a hub affixed to a shaft to be rotated about an axis, and a carrier for the impeller; a body defining a recess and having wall structure defining a frusto-conical taper extending toward an eye, the body defining two outer volute sections opening toward the periphery of the recess, the body also forming a water inlet passage extending in registration with the eye, which defines a water inlet port; the rotor assembly received in the recess so that the hub is centered relative to the eye and projects into proximity to the eye when the carrier is attached to the body, the impeller having blades rotating in proximity to the frusto-conical wall structure; whereby water received in the eye from the inlet passage flows between the rotating hub and the frusto-conical wall structure and between the blades in an outward direction to the volute sections as the impeller rotates.
