Abstract

背圧室を区画するシール部材の設置スペースを可及的に小さくし、スペース確保が難しい旋回スクロール部材の背面側スペースにおいて、背圧室の形成を容易化して設計自由度を高めることができるスクロール型流体機械を提供する。旋回スクロール部材（３３）と固定支持部材（３１）との間に、シール部材（５１）を介して高圧ガスが導入される背圧室（５０）を区画形成してなるスクロール型流体機械において、シール部材（５１）を環状Ｕシール部材（５３）により構成し、環状Ｕシール部材（５３）を旋回スクロール部材（３３）の背面と直交する方向に向け、固定支持部材（３１）の側面（シール面）（５０Ａ，５０Ｂ）に一側面を接触させて設置した。
