のである。With the above configuration, the refrigerant gas returning from the cooling device (not shown) is guided to the suction muffler 9 through the insertion pipe T, and is guided to the suction muffler 9 through the communication pipe 10. Opening 1 ob, cap 11
The suction pipe passes through the suction hole 6a and enters the cylinder e, but since the refrigerant gas flows while contacting the synthetic resin wall, it is less affected by heat from the cylinder head 4, and the refrigerant gas is less likely to be heated, so the volumetric efficiency can be improved. I can figure it out. Further, since the mounting leg 10a comes into airtight contact with the cap 11 to form a suction chamber with poor heat conduction, assembly can be easily performed. Furthermore, since the cylinder head 4 is mounted so as to be sandwiched between the legs 10a and the communication pipe 1o, the suction muffler 9 does not rotate all over, so it can be easily fixed.

め、組立作業性が向上する。Effects of Komei As mentioned above, this research is inserted into the insertion hole of the communication pipe cylinder head and fixed by sandwiching the cylinder head with the mounting legs, so when the suction muffler is fixed, the rotation is prevented, making assembly work easier. Improves sex.
また、冷媒ガスは連通管の脚とキャップとで形成する熱
伝導率の低い室から、吸入穴へ流れるので冷媒ガスの加
熱をおさえ、体積効率の向上が図れるものである。In addition, since the refrigerant gas flows from the chamber with low thermal conductivity formed by the leg and the cap of the communicating tube to the suction hole, heating of the refrigerant gas is suppressed and the volumetric efficiency can be improved.
