摘要： A two-step roller finger follower having a high-lift follower portion that pivots on a pivot shaft disposed on a low-lift follower portion, and having a lost-motion spring disposed between the high-lift follower and the low-lift follower to bias the high-lift follower toward the high lift cam lobe.

摘要： In a two-step roller finger cam follower, a slider arm for engaging a high-lift cam lobe is pivotally mounted to the body and can variably engage a latch pin slidably disposed in a latch pin channel. A second channel in the body opens onto the slider arm and contains a timing pin that rides on an eccentric surface of the slider arm to extend or retract the timing pin. A bore between the latch pin channel and the timing pin channel contains a ball controlled by the timing pin to lock the latch pin into an engaged or disengaged position. The cam lobe has an undercut region such that the latch pin is allowed to move between engaged and disengaged position only when the slider arm is in the undercut region of the cam lobe. The latch pin can move only when the timing pin permits.

摘要： A two-step roller finger follower having a high-lift follower portion that rotates relative to a low-lift follower portion about a pivot shaft, including a lost-motion compression spring disposed in a linear bore formed in the high-lift portion to exert force against an curved pad on the back side of the valve pallet of the low-lift portion. The spring is retained and guided in its bore by a spring retainer having a planar bottom for engaging the curved pad. Preferably the retainer is a cup positioned in the spring bore such that the stroke of the cup is limited, to prevent leak-down of the associated hydraulic lash adjuster. Driving the spring by a linear-acting retainer in a linear bore causes the spring to be compressed linearly, resulting in a highly stable and predictable spring rate.

摘要： A two-step finger follower rocker arm assembly for cooperating with high-lift and low-lift cam lobes of an engine camshaft. The rocker arm assembly includes a follower body for engaging an hydraulic lash adjuster and a valve stem. A central well contains a roller for following the central low-lift cam lobe. Pivotably mounted on the body are lateral high-lift followers, including sliders or rollers, for following the lateral high-lift cam lobes. A latch block disposed on the body surface is slidable by piston and spring means between first and second positions to engage and thereby alternatively latch and unlatch the high-lift followers. In latched position, the rocker arm assembly acts in high-lift mode; in unlatched position, in low-lift mode.

摘要： A two-step roller finger follower including an elongate body having side walls defining coaxially disposed shaft orifices, a pallet end and a socket end interconnecting with the side walls to define a slider arm aperture, and a latch channel. The socket end is mountable to an hydraulic lash adjuster, and the pallet end is matable with a valve stem. A slider arm for engaging a high-lift cam lobe is disposed in the slider arm aperture and has a first end pivotably mounted to the pallet end of the body and the second end forming a slider tip for engaging an activation/deactivation latch. The latch is slidably disposed in the latch channel, and the latch has a nose section for selectively engaging the slider tip. A spool-shaped roller having first and second roller elements fixedly attached to the shaft is rotatably disposed in the shaft orifices, the roller being adapted to follow the surface motion of low-lift cam lobes. Preferably, the shaft is journalled in roller or needle bearings which extend between and through the first and second shaft orifices, being thus exposed to normal copious oil flow through the RFF.

摘要： A valve deactivation lifter including means for restricting relative rotation between the pin housing and the lifter body. When used in a V-style or slant engine, a prior art deactivation lifter can be subject to oil drainage during engine shutdown if the oil supply port in the pin housing rests in the “down” position. In an improved lifter, relative rotation between the pin housing and the lifter body is limited and the pin housing is oriented such that the oil supply port is never on the underside of the pin housing. Rotation may be limited by any of several means, for example, a ball disposed in a dimple in the pin housing and extending into a longitudinal groove in the lifter body, and a flat on the pin housing and locking means installed in the lifter body to engage the flat and thus prevent rotation of the pin housing.
摘要翻译：一种阀门失活升降机，包括用于限制销壳体和升降机体之间的相对旋转的装置。当用于V型或倾斜发动机时，如果销壳中的供油口处于“向下”位置，则现有技术的停用升降机可以在发动机关闭期间进行排油。在改进的升降机中，销壳体和升降机体之间的相对转动受到限制，并且销壳体定向成使得供油口不会在销壳体的下侧。旋转可以通过几种手段中的任何一种来限制，例如，设置在销壳体中的凹坑中并延伸到升降机主体中的纵向凹槽中的球，以及安装在升降机主体中的销壳体和锁定装置上的平面接合平板，从而防止销壳体旋转。

摘要： 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.

摘要： 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.

摘要： A deactivation valve lifter includes a lifter body. The lifter body has a first end configured for engaging a cam of an engine and at least one annular pin chamber. A pin housing includes a pin housing bottom. The pin housing bottom defines at least one pin stop aperture and a radially directed pin bore. A deactivation pin assembly is disposed within the pin bore and includes pin members. The pin housing is concentrically disposed within the lifter body. A portion of each pin member may be disposed within the annular pin chamber to thereby selectively couple and decouple the lifter body to the pin housing. A drain aperture defined by the pin housing bottom extends from the pin bore to an outside surface of the pin housing. A stop pin is disposed in the at least one pin stop aperture for limiting the inward motion of the pin members.
