摘要： A washer member disposed in a valve housing of an engine is disclosed. The washer member resiliently supports an injector push member via an elastic member and receives a pair of hydraulic lash adjusters for operating an inlet valve and an outlet valve of a cylinder of the engine. The washer member includes a base portion adapted to abut a support member disposed within the valve housing. The support member defines a clearance with the valve housing to movably dispose the pair of hydraulic lash adjusters within the valve housing. The washer member further includes a side portion extending from the base portion. The side portion is configured to define a lateral movement of the elastic member within a tolerance limit. The side portion is further configured to define a rotational movement of the washer member within a tolerance limit.

摘要： A rocker base is disclosed for use with a valve actuation system. The rocker base may have a housing with a top, a bottom, side walls connecting the top to the bottom, and end walls disposed between the side walls. The rocker base may also have rocker arm supports located inside the housing and integrally formed with the side walls, and an injector spring pad extending from one of the end walls toward a center of the housing. The rocker base may further have a rib connecting the injector spring pad to one of the rocker arm supports.

摘要翻译： 公开了一种设置在发动机的阀壳体中的垫圈构件。 垫圈构件通过弹性构件弹性地支撑注射器推动构件并且接收用于操作发动机气缸的入口阀和出口阀的一对液压间隙调节器。 垫圈构件包括适于邻接设置在阀壳体内的支撑构件的基座部分。 支撑构件与阀壳体限定了间隙，以将一对液压间隙调节器可动地设置在阀壳体内。 垫圈构件还包括从基部延伸的侧部。 侧部构造成限定弹性构件在公差限度内的横向运动。 侧部进一步构造成限定垫圈构件在公差极限内的旋转运动。
