Abstract

 高圧室(背圧室)の圧力P1と低圧室の圧力P2との圧力比(P1/P2)が低くなるような場合でも、旋回スクロールの径を大きくすることなく、旋回スクロールを固定スクロール側に確実に押し付けることができ、旋回スクロールの壁体の先端面と固定スクロール端板の底面との間からの流体の漏洩を防止することができるスクロール型流体機械を提供すること。旋回スクロール端板(13a)の背面周縁部に、オルダムリング(10)の一端部を摺動可能に収容するオルダムキー溝(17)が形成されたスクロール型流体機械であって、シール部材(18)に、背圧室内から前記オルダムキー溝(17)内への流体の流れを遮断する舌片部(18a)が形成されている。
