Abstract

　多段の回転流体機械において、効率低下を小さくするとともに、旋回失速を抑制する回転流体機械のシール装置および回転流体機械を提供する。回転軸（３）を回転可能に収納する筐体（２）と、回転軸（３）に対して径方向または軸線方向の少なくとも一方に沿って延びるとともに、間を通過する流体に回転軸（３）の回転方向に向かう流速成分を与える複数の案内部（３１）と、複数の案内部（３１）の端部をつなぎ、複数の案内部（３１）の間の空間と外側の空間とを仕切る仕切り部（３２）と、径方向に延びる環状突起であって、回転軸（３）または筐体（２）との間に第１隙間（３６）を形成し、複数の案内部（３１）に向かって流れる流体を遮る第１シール部（３４）と、環状突起であって、回転軸（３）または仕切り部（３２）との間に第２隙間（３５）を形成し、外側の空間を流れる流体を遮る第２シール部（３３）と、が設けられていることを特徴とする。
