タリーポンプ。[Claims for Utility Model Registration] ゛(1) A circular pump comprising an impeller having a plurality of radial blades made of a flexible elastic body, with an arcuate cam protruding from a part of the inner circumference between the suction and discharge ports. In the case where the cam is elastically attached to the casing, the chord length of the cam is set to be shorter than the straight line distance between the vertices of the impeller blades in the free state, and the suction side end thickness T is smaller than the maximum thickness part T.
A rotary pump for filth, characterized in that T' and T' are set approximately equal, and an inner circular arc is formed between T and T'. (2) The thickness of the cam at the suction side end is T compared to the maximum thickness T.
The rotary pump for filth according to claim 1, wherein T and T' are set equal and are formed by arcs concentric with the inner and outer sides of the space between T and T'. (3) The cam has a suction side end thickness T with respect to the maximum thickness part T.
The rotary pump for filth according to claim 1, which is registered as a utility model, is formed by setting T and T' slightly smaller and having a radius that gradually increases from the center of the inner impeller between T and T'.
