ABSTRACT:
A regenerative turbine fuel pump for motor vehicles including a flat disc-shaped impeller having radial vanes in an annular pump chamber, the pump having strippers in the pump chamber oriented obliquely relative to the direction of rotation of the vanes and inlet and discharge ports disposed generally at the apexes of wedge-shaped ends of the pump chamber grooves defined by the oblique sides of the strippers. The vanes are progressively covered and uncovered by the oblique sides of the strippers as the vanes enter and leave the confines of the strippers to attenuate pressure pulses and minimize audible tones associated with such pressure pulses.
