Definitions

  • a fuel supply apparatus comprises a rotary pump having a pumping chamber, the volume of which varies in conjunction with a rotation of a rotor, pressurizing the fuel sucked into the pumping chamber and discharging the pressurized fuel.
  • the rotary pump is characterized in that, multiple through-holes are formed in a rotor, wherein the through-holes pass through in the rotor in an axial direction, and side clearances formed at both sides of the rotor are communicated with each other by those through-holes.
  • the inner rotor Because of the through-holes formed in the inner rotor, which is driven by a cam shaft, the inner rotor can be floated. As a result, metal contacts between the inner rotor and other parts are suppressed during the rotation of the inner rotor, and thereby the problems of the abnormal wear, seizures and the like can be suppressed.
  • the main pump 2 comprises a cam shaft 4 to be rotated being driven by a diesel engine (not shown), a pump housing 5 for rotationally supporting the cam shaft 4, a plunger 7 being driven by the cam shaft 4 for reciprocally moving in a cylinder 6, and so on.
  • the vane type pump has, as shown in Fig. 5, a rotor 25 formed with multiple vane grooves 25a at its outer periphery at equal distance in the circumferential direction, and vanes 26 respectively and movably inserted into the vane grooves 25a.
