Description
その後、圧縮された冷媒ガスは、前記固定スクロール１１０及び前記フレーム１６０の
外周面に形成されている通路（図示せず）を介して前記密閉容器１００内の前記駆動部３
側に流れ、ここから吐出管１５０を介して密閉容器１００外の冷凍サイクル等へ吐出され
る。従って、前記密閉容器１００内の空間は吐出圧力に保たれる。
After that, the compressed refrigerant gas passes through the passages (not shown) formed in the outer peripheral surfaces of the fixed scroll 110 and the frame 160, and the driving unit 3 in the hermetic container 100.
To the outside, and is discharged from here to a refrigeration cycle or the like outside the closed container 100 through a discharge pipe 150. Therefore, the space inside the closed container 100 is maintained at the discharge pressure.
また、本実施例４によれば、複数の前記支持ボルト１３８の内周側における前記副軸受ハウジング１３３と前記ポンプケース１０６ｅとの間に、円環状の弾性支持部材１９０を設ける構成としているので、弾性支持部材１９０を１つにすることができ、実施例１〜３のものに対して、部品点数を削減してコスト低減を図れる効果もある。 Further, according to the fourth embodiment, since the annular elastic support member 190 is provided between the sub bearing housing 133 and the pump case 106e on the inner peripheral side of the plurality of support bolts 138, The number of elastic supporting members 190 can be one, and there is an effect that the number of parts can be reduced and the cost can be reduced as compared with those of the first to third embodiments.
