Abstract
An eccentric vane pump to be mounted on e.g. an automobile alternating current generator, and having a housing, an annular disc adapted to be fixed to the housing to define a working chamber in association with the housing, a rotor rotatively received within the working chamber and provided with radial vanes slidably mounted therein, a shaft rotatively mounted on the end frame of the generator and adapted to be drivingly connected the rotor through a spline joint with an eccentricity being left between the centers of the shaft and the working chamber, and an oil seal secured to the inner periphery of the disc so as to sealing abut the shaft at its inner periphery to hermetically seal the working chamber. A spacer can be used to insure tight abuttment of the oil seal against the shaft.
