ポンプ。[Claims for Utility Model Registration] A pump housing that defines a pump chamber having an inner circumferential surface of the pump by a cylindrical peripheral wall, a front cover, and an axial partition wall, and is equipped with an inlet and a discharge port that communicate with the pump chamber; extending into the pump chamber through an axial bulkhead in the pump housing;
The pump chamber has a rotating shaft extending in the axial direction at an eccentric position with respect to the inner circumferential surface of the pump chamber, and a plurality of flexible vanes extending in the radial direction at predetermined angular intervals around the rotating shaft. and a rotating body that rotates eccentrically by airtightly partitioning the pump chamber in the pump housing by the flexible vanes, and the rotation of the rotating body brings the pump chamber on the suction port side into a negative pressure state. In the flexible impeller type rotary pump that discharges liquid from the suction port toward the discharge port, the pump chamber on the suction port side and the seal chamber on the outside of the pump chamber are negative with respect to the axial partition wall of the pump housing. A flexible impeller rotary pump characterized by having a negative pressure communication hole that communicates in a pressure state.
