Description
回転軸とハウジングとの間の隙間を軸封するシールリングであって、
摺動面には、周方向に配置され外径側に開口する引き圧を発生させるための複数の傾斜溝と、被密封流体側に開口し前記傾斜溝の内径側まで外径方向に延びる供給溝と、が設けられている。
これによれば、供給溝の内径側の開口から導入された高圧の被密封流体が外径側において回転軸の回転時に傾斜溝で生じる外径方向への流れによる引き圧により引き込まれ、供給溝と傾斜溝との間に被密封流体の外径方向の流れが形成されることとなるため、供給溝と傾斜溝との間において周方向にバランスよく流体膜を形成可能として、広い回転域で安定した潤滑性能を発揮できる。
これによれば、被密封流体の径方向の流れが形成される供給溝と傾斜溝との間がシール部により径方向に分離されるため、シール部において周方向にバランスよく流体膜が形成される。
これによれば、シール部に対する被密封流体の径方向の流れが周方向にバランスよく形成される。
これによれば、供給溝の内径側の開口から導入された高圧の被密封流体が連通溝により周方向に供給されるため、シール部に対する被密封流体の径方向の流れが周方向にバランスよく確実に形成される。
これによれば、傾斜溝で生じる負圧を動圧溝で生じる正圧により一部相殺できるため、シール部において被密封流体の径方向の流れが形成されやすい。
