Title (EN) VALVE ASSEMBLY, PISTON UNIT AND OIL DAMPER
(FR) ENSEMBLE SOUPAPE, UNITÉ DE PISTON ET AMORTISSEUR À HUILE
(ZH) 阀体组件、活塞单元及油压减振器
Abstract:
(EN) Disclosed is a valve assembly (22) arranged on a piston body (21) of an oil damper (3), wherein a valve cover (221) is provided with a fluid hole (2213). Oil above the piston body (21) successively passes through the fluid hole (2213) and a discharge hole (211) so as to realize unloading and vibration-damping functions, thus avoiding the geometrical tolerance between a valve cover (121) and a valve core (122) being influenced when an unloading opening (1222) is machined in a side wall of a blind hole (1221) of the valve core (122) in the prior art, thereby ensuring that the valve cover (221) and a valve core (222) fit precisely and further making the valve assembly (22) have a stable quality and a stable precision performance. Further disclosed is a piston unit (2) applied to the oil damper (3) and provided with the valve assembly (22) mentioned above, wherein same has a stable quality and stable precision performance. Further disclosed is an oil damper (3) provided with the piston unit (2) mentioned above, wherein same has a stable quality and stable precision performance.
(FR) L'invention concerne un ensemble soupape (22) disposé sur un corps de piston (21) d'un amortisseur à huile (3), un cache-soupape (221) étant pourvu d'un trou à fluide (2213). L'huile au-dessus du corps de piston (21) traverse successivement le trou à fluide (2213) et un trou de décharge (211) de manière à réaliser des fonctions de décharge et d'amortissement des vibrations, ce qui permet d'éviter que la tolérance géométrique entre un cache-soupape (121) et une pièce intérieure de soupape (122) ne soit influencée lorsqu'une ouverture de décharge (1222) est usinée dans une paroi latérale d'un trou borgne (1221) de la pièce intérieure de soupape (122) dans l'état de la technique, afin de garantir que le cache-soupape (221) et une pièce intérieure de soupape (222) s'ajustent avec précision tout en stabilisant encore plus la qualité et les performances de précision de l'ensemble soupape (22). L'invention concerne en outre une unité de piston (2) appliquée à l'amortisseur à huile (3), pourvue de l'ensemble soupape (22) susmentionné, et offrant une qualité et des performances de précision stables. L'invention concerne en outre un amortisseur à huile (3) pourvu de l'unité de piston (2) susmentionnée, et offrant une qualité et des performances de précision stables.
(ZH) 一种阀体组件(22),设置于油压减振器(3)的活塞本体(21)上,在阀罩(221)上设置有流体孔(2213),所述活塞本体(21)上方的油液依次通过所述流体孔(2213)和排出口(211)来实现卸荷和减振功能,避免了现有技术在阀芯(122)盲孔(1221)侧壁上加工卸荷口(1222)时对阀罩(121)和阀芯(122)之间形位公差的影响,保证了阀罩(221)与阀芯(222)之间的配合精度,进而使阀体组件(22)具有稳定的质量和精度性能。一种活塞单元(2),应用于油压减振器(3)上,设置有前述的阀体组件(22),具有稳定质量和精度性能。一种油压减振器(3),设置有前述的活塞单元(2),具有稳定质量和精度性能。
