Patent ID: 8579613

Claim:
A vane pump comprising: a housing including a cylindrical part, a first board closing an end of the cylindrical part in an axis direction, and a second board closing the other end of the cylindrical part in the axis direction, wherein a pump chamber is defined among the cylindrical part, the first board and the second board; a rotor having an approximately column shape rotatably arranged in the pump chamber, the rotor having a center hole passing through the rotor in the axis direction at an approximately center position, and a plurality of vanes slidable on an inner wall of the housing; and a motor having a shaft fitted into the center hole of the rotor, the motor rotating the rotor by rotating the shaft, wherein an imaginary plane is defined to bisect the pump chamber in the axis direction, the housing has a first inlet port and a second inlet port located symmetrical with each other with respect to the imaginary plane, the housing has a first outlet port and a second outlet port located symmetrical with each other with respect to the imaginary plane, the first outlet port is located at the end of the cylindrical part in the axial direction, and extends in a radial direction of the cylindrical part, and the second outlet port is located at the other end of the cylindrical part in the axial direction and extends in the radial direction of the cylindrical part.
