Claims

[Scope of utility model registration request]

In a valve in which a valve body reciprocally arranged in a valve chamber of a housing opens and closes a passage by contacting and separating from a valve seat, an annular protrusion of a rubber-like elastic body is provided at a position where the valve part contacts the valve seat surface. . A valve characterized in that a stroke limiting stopper that is shorter in the axial direction than the annular projection is provided on the valve body on the outer periphery of the annular projection.
