Abstract

　本発明のスクリュ圧縮機は、ケーシング内に互いに咬合して回転可能に収容され、流体を吸込んで圧縮して吐出する雌雄一対のスクリュロータと、スクリュロータの少なくとも一方の回転軸となるロータ軸に内環が固定され、ケーシングに外環が固定されてロータ軸のスラスト力を受ける主スラスト軸受と、ロータ軸に内環が固定され、外環がケーシングに対して移動可能なバランス軸受と、バランス軸受の外環を保持する、軸受保持部材と、流体圧によって軸受保持部材を吐出側に押圧する流体圧印加手段とを備える。このような構成により、ロータ軸のスラスト荷重を低減でき、バランスピストンによる回転負荷の増加と、バランスピストンのシール漏れの危険性とが排除できる。
