    • A switchable valve train member, such as a deactivating valve lash adjuster or a deactivating hydraulic valve lifter, including a pin housing slidably disposed within an axial bore in a body. A transverse bore in the pin housing contains a retractable locking pin that engages a feature in the body including a locking surface whereby the body and the pin housing are locked together for mutual actuation by rotation of a cam lobe. A lash ring at the outer end of the body includes a portion extending into the axial bore that limits the travel of the pin housing within the body and thereby sets the internal mechanical lash in the switchable member. The axial thickness of the lash ring may be varied between assemblies to compensate for manufacturing variation in the components and is secured to the body in any of various configurations.

    • A deactivating hydraulic lash adjuster comprising a pin housing slidably disposed in a body and having at least one lock pin disposed in a transverse bore for extending into a receiver feature in the body to lock the two together during periods of engine operation in valve non-deactivation mode. The present improvement consists in providing a first orienting feature for the lash adjuster body that engages a second orienting feature on an engine head to provide a preferred and fixed orientation of the body within a bore in the engine head. In a currently preferred orientation, the axis of the at least one lock pin is parallel to the axis of the engine camshaft. The orientation of the lock pin(s) to the body is made invariant by insertion of a pin through a radial bore in the body into a longitudinal groove in the pin housing.

    • An internal combustion engine is equipped to supply the camshaft bearings with pressurized oil via a first dedicated oil gallery independently of the hydraulic lash adjusters (HLAs) and any valve deactivation devices which are supplied from a second dedicated oil gallery. The galleries may be connected at their downstream ends and a flow restriction is placed in a connecting passage or within each HLA. An improved HLA is similar to a prior art HLA except that the prior art annular oil distribution groove in the outer surface of the HLA body is eliminated to prevent communication of the primary engine oil gallery with the HLA. The secondary gallery is formed remotely from the first oil gallery in the HLA residence bore in the engine, and the HLA is prevented from rotating within the residence bore.

    • A two-step finger follower rocker arm assembly including a follower body having a socket at a first end for engaging a hydraulic lash adjuster and a pad at an opposite end for engaging a valve stem. A passage through the follower body in the direction of actuation by an engine cam lobe is slidingly receivable of a slider member for variably engaging a central cam lobe, preferably a high-lift lobe. A latch member driven by a piston selectively locks the slider member to the follower body such that the follower follows the motion of the central cam lobe. When the latch member is disengaged from the slider member, the slider member slides within the follower body. The body is provided with a stud extending from an upper surface thereof and formed as an extension of the passage for supporting the slider over a greater length thereof such that a counter-torque moment on the slider in the passage is reduced.

    • An improved deactivation hydraulic lash adjuster wherein the prior art lost motion spring or springs formerly located within the body of the DHLA and below the pin housing are either omitted completely or are reduced in length, spring force, and/or number and are augmented hydraulically, allowing a shorter, more compact lifter body and reduced overall lifter length. The prior art lost motion spring chamber becomes a hydraulic chamber connected to a new pressurized oil supply gallery containing an accumulator in the engine. An embodiment having no lost motion spring and solely hydraulic lost motion return can be even shorter than a spring-hydraulic hybrid because the potential hydraulic pressure to be brought against the pin housing is not a function of the length of the lost motion chamber, which length is limited only by the required displacement of the pin housing.
    • 一种改进的失活液压间隙调节器,其中先前位于DHLA主体内并在销壳下面的现有技术的空转弹簧或弹簧或者完全省略或者在长度,弹簧力和/或数量上都被减小, 允许更短,更紧凑的升降机体,并缩短整体升降机长度。 现有技术的空运弹簧室成为连接到在发动机中容纳有蓄能器的新的加压供油库的液压室。 具有无运动弹簧和单独的液压失速运动返回的实施例可以甚至比弹簧 - 液压混合动力更短,因为要抵靠销壳体的潜在液压压力不是空转室长度的函数, 仅由引脚壳体的所需位移限制。

    • Valve lift variation associated with a deactivation roller hydraulic valve DRVHL (DRHVL) can result in unacceptable valve overlap and idle conditions for an internal combustion engine. Two sources of length variation in a DRHVL are leakdown and residual mechanical lash. Total length variation is the sum of these two factors, and each factor has an associated tolerance. In the prior art, the two factors are independent, resulting in a total population variation that is the sum of the two independent variations. A DRHVL assembly process in accordance with the invention includes the step of associating leakdown test results for individual lash adjusters with residual lash results by adjusting the residual lash characteristics of individual DRHVL assemblies to complement the leakdown characteristics in minimizing total length variation in the population of assembled DRHVLs.
    • 与停用辊液压阀DRVHL(DRHVL)相关联的气门升程变化可能导致内燃机不可接受的阀重叠和空转状态。 DRHVL中两个长度变化的来源是泄漏和残留的机械间隙。 总长度变化是这两个因素的总和,每个因素都具有相关的公差。 在现有技术中,这两个因素是独立的,导致总体总体变化是两个独立变化之和。 根据本发明的DRHVL组装方法包括以下步骤:通过调节各个DRHVL组件的残余睫毛特性来将各个间隙调节器的泄漏测试结果与残余睫毛结果相关联,以补充泄漏特性,从而最小化装配的群体中的总长度变化 DRHVLs。
