摘要：
Systems for actuating at least two engine valves comprise a valve bridge operatively connected to the at least two engine valves and having a hydraulically-actuated lost motion component. The lost motion component comprises a lost motion check valve disposed therein. A rocker arm has a motion receiving end configured to receive valve actuation motions from a valve actuation motion source and a motion imparting end for conveying the valve actuation motions and hydraulic fluid to the lost motion component. The rocker arm is in fluid communication with a hydraulic fluid supply. The systems also comprise an accumulator in fluid communication with the hydraulic fluid supply and disposed upstream of the lost motion check valve. In all embodiments, a fluid supply check valve may be disposed upstream of the accumulator and configured to prevent flow of hydraulic fluid from the accumulator back to the hydraulic fluid supply.
摘要（中）：
用于致动至少两个发动机气门的系统包括可操作地连接到所述至少两个发动机气门并具有液压致动的空动部件的气门桥。 空动组件包括设置在其中的空转止回阀。 摇臂具有构造成接收来自气门致动运动源的气门致动运动的运动接收端和用于将气门致动运动和液压流体传送至空动组件的运动传递端。 摇臂与液压流体供应流体连通。 该系统还包括与液压流体供应流体连通并设置在空动止回阀上游的蓄压器。 在所有实施例中，流体供应止回阀可以设置在蓄压器的上游并且构造成防止液压流体从蓄压器流回液压流体供应。
