Abstract
A gear pump is provided and includes an inlet port which terminates, in the pumping direction of the rotor set, in a radially inwardly extending ramp portion. The ramp portion operates to direct working fluid from an inlet radially inwardly into a pumping chamber of the rotor set which is passing over the ramp portion. By closing the pumping chamber at a radially inwardly point, the filling efficiency of the pumping chamber is improved, reducing cavitation and/or operating noise of the pump.
