摘要： A thrust plate is provided. The thrust plate includes a first side surface and a second side surface. The thrust plate also includes an inner surface and an outer surface extending axially between the first and second side surfaces respectively. Further, the inner and outer surfaces of the thrust plate define an inner diameter and outer diameter respectively. The thrust plate further includes a number of mounting apertures extending between the first and second side surfaces. The number of mounting apertures is defined proximate to the outer diameter of the thrust plate. A wear layer is positioned radially inward from the mounting apertures. The wear layer is integrated into a stepped portion defining a wear prone area on the first and/or second side surfaces. Further, the wear layer is made of a material different from that of a core of the thrust plate.

摘要： A multi-valve actuating valve bridge for an engine is provided. The valve bridge includes a rocker arm engaging tappet head and at least two arms extending transversely of the rocker arm and engaging the tappet head. The valve bridge further includes a valve stem guide pocket provided on each of the arms. The valve stem guide pocket includes a valve stem contact face and a tapered surface extending from the valve stem contact face towards an opening of the valve stem guide pocket. The tapered surface defines an inverted frusto-conical cavity. A first inner diameter of the valve stem guide pocket at the valve stem contact face is greater than a second inner diameter of the valve stem guide pocket at the opening.

摘要翻译： 提供了一种用于发动机的多阀致动阀桥。 阀桥包括摇臂接合挺杆头和至少两个臂，其横向于摇臂并且与挺杆头接合。 阀桥还包括设置在每个臂上的阀杆引导槽。 阀杆引导袋包括阀杆接触面和从阀杆接触面向阀杆引导槽的开口延伸的锥形表面。 锥形表面限定了倒立的截头圆锥形腔。 在阀杆接触面处的阀杆引导槽的第一内径大于开口处的阀杆引导槽的第二内径。
