PURPOSE:To prevent suction gas from being heated on high temperature gas within a closed casing and improve the energy efficiency of a compressor by connecting a suction tube fixed to said casing to the suction hole of the compressor with a flexible tube. CONSTITUTION:A suction tube 59 is fixed to the exterior of a enclosed casing 51. One end of a coil spring or a flexible tube 59 is fixed to a suction hole formed on the cylinder head 57 of a compressor arranged in said enclosed casing 51. And the other end of the coil spring or the flexible tube 59 is freely located within the suction tube 59 so that suction gas is sucked into the compressor without being heated.
