Power transmission
This patent describes a fuel pump for aircraft turbine engines and like applications having a predetermined net liquid fuel fluid flow requirement and being adapted to operate at a predetermined maximum vapor/liquid inlet ratio without cavitation, the pump comprising a positive displacement vane pump. It comprises: a housing, a rotor mounted for rotation within the housing and having radially extending peripheral slots, vanes individually slidably disposed in the slots, means forming a cam ring within the housing radially surrounding the rotor and having a radially inwardly facing vane track defining at least one arcuate fluid pressure cavity between the rotor and the cam ring, a fluid inlet in the housing including a first fluid inlet port opening into the cavity at a leading circumferential edge thereof with respect to direction of rotation of the rotor within the housing.
