Claims

[Scope of Claim for Utility Model Registration] A casing equipped with a suction port and a discharge port, a rotor housed in the casing and driven to rotate, an inner circumferential surface of the casing, an outer circumferential surface of the body of the rotor, and flanges on both sides thereof. a partition block for preventing a short circuit between the suction port and the discharge port in a fluid passage defined by an inner surface; a partition block that is swingably supported by the rotor and extends into the fluid passage; The movable block has a plurality of movable blocks retracted from the fluid passage into the rotor, and the movable block has a cylindrical outer circumferential surface that is the same as the outer circumferential surface of the body of the rotor, and a cylindrical rotation centering on the movable block pivot shaft. In the rotary pump, the rotary pump is fitted in a recess consisting of a cylindrical rotating surface formed on the outer circumferential surface of the body of the rotor and aligned with the cylindrical rotating surface, the outer circumferential surface of the flange portion of the rotor or Three or more annular grooves are provided on one of the inner circumferential surfaces of the cylindrical part of the casing surrounding this, and an annular endless molded seal is fitted into at least both ends of the annular grooves,
A rotary pump characterized in that the annular grooves that are not located at both ends are communicated with holes penetrating the casing wall.
