Abstract: PURPOSE:To effectively restrain flow change of compressed refrigerant gas by introducing discharge gas from a compression element stored in a closed container fixed with a discharge pipe to the discharge pipe by a discharge line, and by providing a restricted part on the discharge pipe. CONSTITUTION:A compression mechanism 1 stored in a closed container 2 compresses refrigerant gas by reciprocal motion of a piston 6 in a cylinder 5 by a crank shaft 8 rotated by an electric motor 3 and discharges it through a discharge muffler, a discharge line 13 and a discharge pipe 14 fastened on the closed container 2 outside. In this case, inside diameter set smaller than the inside diameter of the discharge line 13 is set by providing a restricted part 14a on a part outside of the closed container 2 in the circumferential direction of the discharge pipe 14. Consequently, change of flow (pulsation) of compressed gas can be damped without preventing enlargement of the size of a compressor and its startability.

Abstract: PURPOSE:To reduce noise generated from the piping of a cooling system or the like due to the flow fluctuation (pulsation) of compressed refrigerant gas. CONSTITUTION:At the time of connecting a discharge line 13 to a discharge pipe 14, pulse suppressing material is provided inside the discharge line 13.
