Claims

[Scope of utility model registration request]

a casing leg provided with a suction port and a discharge port; a rotor housed within the casing and driven to rotate; and a fluid flow path defined by the inner surface of the casing and the outer peripheral surface of the rotor. a partition block for preventing short circuit with the discharge port; a wear-resistant sealing material installed in the partition block and slidingly contacting the outer peripheral surface of the rotor; , and a plurality of movable blocks retracted from the fluid flow path into the rotor, the movable blocks having a cylindrical outer circumferential surface that is the same as the outer circumferential surface of the b-ta, and a cylindrical shape centered on the pivot point. 1. A rotary pump, comprising a rotating surface, the pump being fitted into a closed recess formed by the cylindrical rotating surface formed in the outer peripheral surface of the mouthpiece and aligned with the cylindrical rotating surface.
