摘要: A low mass two-step valve lifter has concentric inner and outer cylindrical cam followers engagable by radially disposed axially aligned lock pins in the outer high lift follower. Both inner and outer followers have cylindrically crowned cam engaging surfaces for high lift capability and low load eccentricity. The lock pins are positioned on the lifter thrust axis normal to the direction of the engine camshaft axis and the skirt has upward seal extensions and downward extending skirt portions adjacent the lock pin openings to maintain seal area. Other skirt portions are cut away to reduce weight. Vent holes in the lock pins discharge collected oil that might interfere with fast pin engagement. A separate passage is provided to feed oil to a hydraulic lash adjuster disposed in the inner follower cylinder. A single guide pin aligns the dual followers with the external bore oil ports and the camshaft cams. Additional features are also disclosed.
摘要翻译: 低质量两级阀提升器具有同心的内外圆柱凸轮从动件,其通过径向设置的轴向对准的锁定销接合在外部高升程跟随器中。 内部和外部跟随器具有圆柱形凸起凸轮接合表面,用于高提升能力和低负载偏心率。 锁定销定位在垂直于发动机凸轮轴轴线方向的升降推力轴上,并且裙部具有向上的密封延伸部和与锁定销开口相邻的向下延伸的裙部以保持密封区域。 其他裙部被切除以减轻重量。 锁定销中的排气孔排出收集的油,这可能会干扰快速销接合。 提供单独的通道以将油供给到设置在内随动缸中的液压间隙调节器。 单引导销将双跟随器与外孔油口和凸轮轴凸轮对齐。 还公开了另外的特征。
