Claims

[Claims for Utility Model Registration] A casing with one end open that surrounds the compressor main body, a front head attached to the open end of the casing, a suction chamber formed on the inner surface of the front head, and the front A suction hole that is bored in the head and has one end open to the outside and the other end opened to the suction chamber, and a pipe joint that is attached to one end of the suction hole and to which a pipe extending from the evaporator of the refrigeration cycle is connected. Prepare,
In a gas compressor that compresses refrigerant gas flowing into the suction chamber from the evaporator through piping, pipe fittings, and suction holes within the compressor main body, the upper end fits into the suction hole, and the lower end fits into the suction hole. A top-open core case placed in a room and having a long hole in a side wall, and a presser part disposed on the inner wall of the suction hole and in contact with a valve seat part and an upper end of the core case on one end side. a stopper whose other end abuts against the pipe joint; a valve body housed in the core case and always biased toward the valve seat; and a stopper disposed around the outer periphery of the suction hole. , and a sealing member that abuts the outer periphery of the pipe joint and the stopper, and the core case is fixed by the holding part of the stopper at the same time as the pipe joint is attached to one end of the suction hole. Stop valve.
