Title (EN) SLIDING COMPONENT
(FR) ÉLÉMENT COULISSANT
(JA) 摺動部品
Abstract:
(EN) Provided is a sliding component having less fluid leakage. In a sliding component 1, positive pressure generation mechanisms 9 and negative pressure generation mechanisms 10 are formed on at least one sliding surface S7 of a sliding member 7, said negative pressure generation mechanisms being disposed further toward the low pressure fluid B side than the positive pressure generation mechanisms 9. The negative pressure generation mechanisms 10 adjacent to each other in the circumferential direction overlap each other in the diameter line direction.
(FR) L'invention concerne un élément coulissant présentant moins de fuites de fluide. Dans l'élément coulissant (1), des mécanismes de production de pression positive (9) et des mécanismes de production de pression négative (10) sont formés sur au moins une face coulissante (S7) d'un élément coulissant (7), les mécanismes de production de pression négative étant disposés plus vers le côté fluide basse pression (B) que les mécanismes de production de pression positive (9). Les mécanismes de production de pression négative (10), adjacents les uns aux autres dans la direction circonférentielle, se chevauchent dans la direction de la ligne diamétrale.
(JA) 流体の漏れの少ない摺動部品を提供する。 少なくとも一方の摺動部材7の摺動面S7に正圧発生機構9と正圧発生機構9よりも低圧流体B側に配置される負圧発生機構10とが形成された摺動部品1であって、周方向に隣接する負圧発生機構10は径線方向において重畳している。
