Claims

[Claims for Utility Model Registration] A main body having a valve chamber, an inlet passage connecting the valve chamber and an inlet, and an outlet passage connecting the valve chamber and an outlet, and a through-hole accommodated in the valve chamber. A ball valve that opens and closes between the inflow passage and the outflow passage by rotation of the valve body, further comprising: a fixed valve seat on which the valve body is seated in the outflow passage; a movable valve seat that is slidably supported by a fixed sleeve that forms an inflow passage and on which the valve body is seated; and a spring that is attached to the fixed sleeve and presses the movable valve seat toward the valve body; A ball valve characterized in that a small through hole is formed in the body between the through hole and a position of the valve body which is located at a position where the inflow path is closed and opens into the inflow path.
