Abstract

　シングルスクリュー圧縮機のケーシング（10）内では、スクリューロータ（40）の側方にスライドバルブ（70）が配置される。スライドバルブ（70）の弁体部（60）は柱状に形成されており、円弧面状に形成された対向面（66）がスライドバルブ（70）と向かい合う。弁体部（60）の対向面（66）には、前方段差部（64）と後方段差部（65）が形成される。各段差部（64,65）では、そこへ吹き付けられる冷媒ガスによって動圧が発生する。そして各段差部（64,65）で発生した動圧が弁体部（60）に作用することで、弁体部（60）の回転が抑えられ、弁体部（60）とスクリューロータ（40）の間隔が保たれる。
