摘要： A fuel pump actuator comprising a body portion and a contact end fitted to the body portion for actuating a mechanical fuel pump in response to a camshaft lobe. A roller mounted to the body portion is configured to ride on the lobe. The contact end of the actuator engages a plunger of the fuel pump. The body portion of the actuator is preferably a body portion of a conventional hydraulic valve lifter and preferably includes a lash adjuster and is reciprocally disposed in a bore on the engine block. Lubrication of the reciprocating actuator is also similar to the lubrication provided to conventional valve lifters and lash adjusters. The contact end of the actuator is configured to reduce the mass of the actuator. Several styles of the contact end and ways of attaching the contact end to the body portion are provided.
摘要翻译：一种燃料泵致动器，包括主体部分和接合端，所述接触端装配到所述主体部分，用于响应于凸轮轴凸起来致动机械燃料泵。安装到主体部分的滚轮被配置成骑在叶片上。致动器的接触端接合燃料泵的柱塞。致动器的主体部分优选地是常规液压气门挺杆的主体部分，并且优选地包括间隙调节器并且往复地设置在发动机缸体上的孔中。往复式致动器的润滑也类似于提供给常规气门挺杆和间隙调节器的润滑。致动器的接触端构造成减小致动器的质量。提供了接触端的几种形式和将接触端附接到主体部分的方式。

摘要： An anti-rotation guide for preventing rotation of a roller follower valve lifter in an internal combustion engine. The guide has an outer surface for engaging an engine bore and an inner surface for slidably receiving the lifter. One end of the guide includes an anti-rotation feature for cooperating with a mating feature on the lifter, preferably flats although other configurations are contemplated within the scope of the invention. The anti-rotation feature may take any of a plurality of shapes, including but not limited to an arm and tang, a flap, and an orifice flat. The guide is installed from an opening in the engine bore proximate a camshaft disposed in the engine block. The cooperating features prevent axial rotation of a lifter within the sleeve but do not inhibit axial or reciprocal motion of the lifter.
摘要翻译：一种用于防止内燃机中的滚子从动阀提升器旋转的防旋转引导件。引导件具有用于接合发动机孔的外表面和用于可滑动地接收升降器的内表面。引导件的一端包括用于与升降机上的配合特征配合的防旋转特征，优选地是扁平的，尽管在本发明的范围内可以考虑其他构造。防旋转特征可以采取多种形状中的任何形状，包括但不限于臂和柄，翼片和孔平面。引导件从位于发动机缸体中的凸轮轴附近的发动机孔中的开口安装。配合的特征防止提升器在套筒内的轴向旋转，但不会阻止升降机的轴向或往复运动。
