ABSTRACT:
A rotary pump for pumping liquid which includes a rotor combination in the form of a vane pump or gear and rotor with pumping chambers disposed circumferentially around the rotor. The chambers progressively increase in the inlet area and ensmall in the outlet area. Pulse absorbtion means are interposed in the fuel passage means to absorb pulses and smooth out the pressurized outlet liquid, thus reducing the pump noise under all conditions of operations.
