る。In FIG. 1, reference numeral 1 denotes a closed container composed of an upper shell 1a and a lower shell 1b, and 2 denotes a compression element elastically supported within the closed container 1. As shown in FIG. 3 is a suction muffler made of a resin having heat insulating properties fixed to the compression element 2, 4 is a suction tube fixed to the upper shell 1a of the closed container 1, and 6 is locked to the suction muffler 3. In the damper collar, the opening 6a of the damper collar 6 is formed into a tapered shape. Reference numeral 6 designates a joint spring, which is a close coil spring, which is locked to the suction tube 4, loosely fitted to the damper collar 5, and communicated with the suction muffler 3. The joint spring 6 is locked parallel to the axial direction of the closed container 1, and at the same time when the upper shell 1a of the closed container 1 is inserted into the lower shell 1b, the joint spring 6 is connected to the suction muffler 3 via the damper collar 5. It is configured to be inserted.

受ける伝導熱も低減され、より断熱効果を高められる。Therefore, by making the opening 6a of the damper collar 6 tapered, the joint spring 6 can be easily inserted at the same time as the closed container 1 is inserted, and the suction path to the suction muffler 3 within the closed container 1 can be easily inserted. It becomes possible to shorten the channel linearly, reducing flow path loss and making it difficult to be heated by the atmospheric gas inside the closed container 1. Further, since the suction tube 4 is fixed to the upper shell 1a rather than the lower shell 1b which is heated by the oil 3o, the conduction heat received from the closed container 1 is also reduced, and the heat insulation effect can be further enhanced.
よって、より低温の吸入ガスをシリンダー7内に送シ込
む事となシ圧縮機の体積効率が向上する。Therefore, lower temperature suction gas is sent into the cylinder 7, and the volumetric efficiency of the compressor is improved.

By communicating through a damper collar with a tapered opening, it has a high heat insulation effect.
It is possible to supply very low temperature suction gas to the cylinder,
A compressor with improved volumetric efficiency and easy assembly can be realized.
