Abstract: A shock absorber for a vehicle includes a pressure tube that defines a fluid chamber and a piston disposed within the fluid chamber. The piston divides the fluid chamber into an upper working chamber and a lower working chamber, and defines a compression passage and a rebound passage. A valve disc assembly of the shock absorber engages the piston and controls the flow of fluid between the upper and lower working chambers. The valve disc assembly includes an orifice check disc and an orifice disc. The orifice disc defines a bleed passage between the upper and lower working chambers. The orifice check disc is disposed between the piston and the orifice disc. The orifice check disc closes the bleed passage as the fluid flows in a first direction and opens the bleed passage as the fluid flows in a second direction opposite of the first direction.

Abstract translation: 用于车辆的减震器包括限定流体室的压力管和设置在流体室内的活塞。 活塞将流体室分成上工作室和下工作室，并限定压缩通道和回弹通道。 减震器的阀盘组件与活塞接合并控制上下工作室之间的流体流动。 阀盘组件包括孔检查盘和孔盘。 孔板在上和下工作室之间限定出血通道。 孔检查盘设置在活塞和孔盘之间。 当流体沿着第一方向流动时，孔口检查盘关闭排放通道，并且当流体沿与第一方向相反的第二方向流动时打开排出通道。
