Claims

[Scope of utility model registration request]

An outer cylinder that is movable in the axial direction while in sliding contact with the inner peripheral surface of the valve seat and has an opening in the peripheral wall; an inner cylinder that is rotatable around an axis while in sliding contact with a surface and has an opening in a peripheral wall; and an inner cylinder that is fixed to one end of the outer cylinder, and the outer cylinder is located at one end of a range of movement in the axial direction. a valve disk that is in close contact with the valve seat in the state; a rod that passes through the outer cylinder, the inner cylinder, and the valve disk in the axial direction; a valve that opens and closes a small valve seat formed on the valve disk;
and an engaging member provided on the rod so as to engage with the valve disk when the valve reaches an open position. ′
