考案が解決しようとする問題点
しかしながら上記のような構成では、シリンダ
にオイルキヤピラリ、連通管をそれぞれ圧入する
ため作業性が悪い上、シリンダヘツドに圧入され
ている連通管は構造上金属製となるため熱伝達が
良く、この連通管を介して吸込まれる冷媒ガスが
高温のシリンダヘツドにより加熱され膨張し、体
積効率の向上が計りにくい。Problems that the invention aims to solve However, in the above configuration, the oil capillary and the communication pipe are press-fitted into the cylinder, which makes it difficult to work, and the communication pipe press-fitted into the cylinder head is structurally made of metal. Therefore, heat transfer is good, and the refrigerant gas sucked in through this communication pipe is heated and expanded by the high-temperature cylinder head, making it difficult to improve the volumetric efficiency.
また、連通管を合成樹脂とした場合熱伝達が金
属に比べて悪いため連通管を介して吸込まれる冷
媒ガスはあまり加熱されず体積効率は向上する
が、一般に合成樹脂は応力に弱いため取り付けが
複雑になるという問題点を有していた。 In addition, if the communication pipe is made of synthetic resin, heat transfer is poorer than that of metal, so the refrigerant gas sucked through the communication pipe will not be heated much and the volumetric efficiency will improve, but synthetic resin is generally weak against stress, so it is difficult to install. The problem was that it became complicated.
