Abstract
A vehicle regenerative-type fuel pump which reduces the possible accumulation and effects of contamination relative to impellers with outer ring members. The outer ring members have non-uniform configurations (slanted, curved, grooved, etc.) which reduce the affects of contamination which can cause wear and roughing of the outer surface resulting in higher torque and reduced pump efficiencies.
Claims7
A fuel pump having a housing, motor, end cap member, impeller and pump cover member, the improvement comprising an outer ring member on the impeller, the outer ring member having an external surface with a non-uniform configuration.
