摘要:
A rocker arm comprising a supply path that communicates with a first lash bore and a first spool bore. A spool is in the spool bore. A hydraulic lash device is in the first lash bore, wherein an outer body is configured to collapse during a first valve lift profile when receiving a low pressure fluid, and wherein the outer body and the inner body are configured to cooperate rigidly when receiving a high pressure fluid during a second valve lift profile. The spool is movable to a first spool position to align the spool notch with a first spool path and a second spool path, and the spool is movable to a second spool position to align the spool notch with the second spool path and an accumulator path. The supply path in to the rocker arm is the only source of fluid to the spool.

摇臂包括供应路径,该供应路径与第一间隙孔和第一阀芯孔连通。 阀芯在阀芯内。 液压间隙装置位于第一间隙孔内,其中外部主体构造成在接收低压流体时在第一气门升程廓线期间塌陷,并且其中外部主体和内部主体构造成当接收到高压力流体时刚性地协作 在第二气门升程曲线期间压力流体。 卷轴可移动到第一卷轴位置以使卷轴切口与第一卷轴路径和第二卷轴路径对齐,并且卷轴可移动到第二卷轴位置以将卷轴切口与第二卷轴路径和蓄能器路径对齐。 进入摇臂的供应通道是流向滑阀的唯一流体源。
