Abstract
A vane pump includes a housing defining a pump chamber; a rotor rotatably arranged in the pump chamber; and a motor to rotate the rotor. An imaginary plane is defined to bisect the pump chamber in an 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, and the housing has a first outlet port and a second outlet port located symmetrical with each other with respect to the imaginary plane.
