Claims

[Claims for Utility Model Registration] (1) A tapered cage-shaped valve body with a plurality of openings and its tip facing the inflow side of the flow path, and a cap-shaped elastic material attached to the inside of the valve body. A check valve having a valve member, the check valve having a support shaft slidably attached to a guide member fixed to the valve body on the outflow side of the flow path from the valve body in the direction of the flow path. A check valve characterized in that the valve member is fixed and the valve member is pressed against the valve body by the elastic force of a spring member installed between the guide member and the valve member. . (2) Utility model registration claim 1, in which the tapered cage-shaped valve body and the cap-shaped valve member are substantially conical.
Check valve as described in section. (3) The check valve according to claim 1, wherein the tapered cage-shaped valve body and the cap-shaped valve member are substantially elliptical conical. (4) The check valve according to claim 1, wherein the opening is also provided at the tip of the tapered cage-shaped valve body. (5) Utility model registration in which a part of the tapered intermediate body of the tapered cage-shaped valve body is inflated outward, and the part of the cap-shaped valve member opposite to the inflated part of the valve body is not inflated. A check valve according to claim 1.
