Claims

[Scope of utility model registration request]

A housing having an inlet and an outlet at symmetrical positions, a rotor having a rotation axis at an eccentric position within an inner cylinder of the housing and having a smaller diameter than the effective diameter of the inner cylinder, and a rotor having a radial axis on the rotor. In a vane pump consisting of a plurality of vanes that are loosely fitted into the inner cylinder, the vanes have a length that is approximately the same as the effective diameter of the inner cylinder, and a notch with a width sufficiently wider than the plate thickness is provided in the middle part so that the vanes can be compared with each other. It is composed of two vanes □ that are orthogonally combined, and these two vanes are slidably and loosely fitted into grooves formed perpendicularly to each other in the diametrical direction of the rotor. vane pump.
