ため取シ付けが複雑になるという問題点を有していた。Problems to be Solved by the Invention However, in the above configuration, the cylinder head 5
The communication pipe 55 that is press-fitted into the cylinder head 4 has a metal structure, so it has good heat transfer, and the refrigerant gas sucked in through the communication pipe 55 is heated by the high-temperature cylinder head 54 and expands, increasing the volumetric efficiency. It is difficult to measure improvements in Furthermore, if the communication pipe 55 is made of synthetic resin, the heat transfer is poorer than that of metal, so the refrigerant gas sucked through the communication pipe 66 is too small! Although the volumetric efficiency is improved without heating, synthetic resins generally have a problem in that they are susceptible to stress, making installation complicated.
