Abstract: A shock absorber includes a pressure sensitive valve assembly that controls fluid flow through the pressure sensitive valve assembly based upon the velocity of the piston assembly in the shock absorber. The pressure sensitive valve assembly restricts fluid flow as the velocity of the piston in a compression stroke increases to increase the damping loads provided by the shock absorber. A secondary valve assembly controls fluid flow through the pressure sensitive valve assembly when the pressure sensitive valve assembly is in a closed position.
Abstract translation: 减震器包括压敏阀组件，其基于减震器中的活塞组件的速度来控制通过压敏阀组件的流体流动。 当压缩冲程中活塞的速度增加时，压敏阀组件限制流体流动，以增加由减震器提供的阻尼载荷。 当压敏阀组件处于关闭位置时，次级阀组件控制通过压敏阀组件的流体流动。

Abstract: A shock absorber for a vehicle includes a pressure tube that defines a fluid chamber. A piston disposed within the fluid chamber divides the fluid chamber into an upper working chamber and a lower working chamber. The piston defines a compression passage and a rebound passage which extend through the piston between the upper working chamber and the lower working chamber. A valve disc assembly engages the piston and controls the flow of fluid between the upper working chamber and the lower working chamber. The valve disc assembly includes a bleed disc that defines an orifice with a substantially non-linear contour. The orifice extends to an outer diameter of the bleed disc, and forms a bleed channel between the upper working chamber and the lower working chamber.
Abstract translation: 用于车辆的减震器包括限定流体室的压力管。 设置在流体室内的活塞将流体室分成上工作室和下工作室。 活塞限定了压缩通道和反弹通道，该通道在上工作室和下工作室之间延伸穿过活塞。 阀盘组件接合活塞并控制上工作室和下工作室之间的流体流动。 阀盘组件包括限定具有基本非线性轮廓的孔口的排出盘。 孔口延伸到排出盘的外径，并且在上部工作室和下部工作室之间形成排出通道。

Abstract: A shock absorber has a housing with a piston rod assembly disposed therein. A first rod guide member is secured within a first portion of the housing so as to be concentrically disposed about at least a portion of the piston rod assembly. A second rod guide member is secured within the housing adjacent the first rod guide member so as to be concentrically disposed about at least another portion of the piston rod assembly. A digital valve assembly is disposed within the second rod guide member and fluidly couples chambers within the shock absorber.
