ABSTRACT:
A roller vane stage (10) for a fuel pump (80) includes an inlet plate (12), an outlet plate (14), and a spacer (16) held therebetween, the spacer having an eccentric inner surface (20) defining a rotor space (18) therein. The roller vane stage (10) further includes a rotor (30) mounted for rotation within the rotor space (18) and the rotor has a plurality of lobes (40), wherein each lobe contains an associated roller (42). Driver slots (44) located in the rotor (30) have a depth less than the thickness (h) of the rotor. Center outlet port (26) in the outlet plate (14) is shaped such that a lobe (40) and its respective roller (42) remains in fluid communication with the center outlet port almost until the lobe begins to communicate with inlet ports (22, 24) in the inlet plate (12). The diameter of the roller (D) and the radius (R) of the rotor (30) are selected such that the radius of the rotor is not less than one half the difference between the rotor radius and the largest radius of the eccentric surface (20).
