Abstract
An improved vane pump assembly is provided. The vane pump assembly includes a housing with an open chamber that is circular in shape when viewed in cross-section and has an inner wall that surrounds the open chamber. A rotor is rotatably disposed in the open chamber of the housing. As with the open chamber, the rotor is circular in shape when viewed in cross-section and has a diameter. The rotor further has at least one through-passage which extends diametrically across the rotor. The rotor is positioned such that it has a center that is offset from a center of the circular open chamber of the housing.
