Title
(EN) SLIDING COMPONENT
(FR) ÉLÉMENT COULISSANT
(JA) 摺動部品
Abstract
(EN) Provided is a sliding component that can stably reduce the frictional resistance of a sliding surface that accompanies eccentric rotation. This sliding component 7 forms a ring shape in which high-pressure and low-pressure fluids face the inside and outside, and has a sliding surface 7a that slides relatively along with eccentric rotation. The sliding surface 7a is provided with, along the circumferential direction thereof, a plurality of high-pressure grooves that open into a space 50 where a high-pressure fluid is present, and a plurality of low-pressure grooves 72 that open into a space 20 where a low-pressure fluid is present.
(FR) L'invention concerne un élément coulissant qui peut réduire de manière stable la résistance de frottement d'une surface coulissante qui accompagne une rotation excentrique. Cet élément coulissant (7) présente une forme annulaire dans laquelle des fluides haute pression et basse pression rencontrent l'intérieur et l'extérieur, et présente une surface coulissante (7a) qui coulisse relativement parallèlement à une rotation excentrique. La surface coulissante (7a) est pourvue, le long de sa direction circonférentielle, d'une pluralité de gorges haute pression qui s'ouvrent dans un espace (50) où un fluide haute pression est présent, et d'une pluralité de gorges basse pression (72) qui s'ouvrent dans un espace (20) où un fluide à basse pression est présent.
(JA) 偏心回転を伴う摺動面の摩擦抵抗を安定して低減することができる摺動部品を提供する。 内外に高圧と低圧の流体が面する円環形状を成し、偏心回転を伴って相対摺動する摺動面7aを有する摺動部品7であって、摺動面7aには、高圧の流体が存在する空間50に開口する高圧溝71と、低圧の流体が存在する空間20に開口する低圧溝72と、がそれぞれ周方向に複数設けられている。
