Claims

[Scope of utility model registration request]

In a vane-type rotary pump, the rotor has two or more notches into which a roller is loosely fitted, and the center of the inner hole formed in the inner wall of the pump housing that forms the outer periphery of the pump is the center of rotation. A rotary pump for liquid, characterized in that the liquid rotary pump is in contact with an inner wall at two or more places, and is provided with two or more suction holes and two or more discharge holes, each at a point symmetrical position with respect to the center of the rotation axis.
