Claims

[Claims for Utility Model Registration] (1) A sleeve pipe is fitted into the opening of a sealed container, an external introduction pipe is fixed inside the sleeve pipe via a welded pipe, and the refrigerant introduced into the external introduction pipe is is drawn into a low-pressure chamber through a suction hole of a cylinder, and the welded pipe is extended to just before the low-pressure chamber, and a substantially central portion of the welded pipe is press-fitted and fixed to the open end of the suction hole. A refrigerant suction device for a hermetic compressor, characterized in that outer circumferential recesses for heat-insulating spaces are formed on both sides of the substantially central portion. (2) The refrigerant suction of the hermetic compressor according to claim 1, wherein the welded pipe has an inner circumferential recess formed at its welded end for inserting and locking the external introduction pipe. Device.
