摘要： A roller finger follower assembly for variably activating a valve in an internal combustion engine includes at least one vertical recessed channel formed inside an outer arm and a shaft. The channel includes a machined upper surface closing the channel. The shaft engages with the recessed channel, the shaft reciprocates within the recessed channel, and the upper surface stops an upward movement of the shaft.

摘要： 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.

摘要： A latching mechanism for variably activating an engine valve in an internal combustion engine includes a rocker arm body having a bore and a socket. A first passage leads from the socket to a first hydraulic chamber formed above a lock pin head. A second passage leads from the socket to a second hydraulic chamber formed below the lock pin head. Since both the first and the second hydraulic chamber receive pressurized oil, it is the diameter of the pin shank that determines the hydraulic force needed to axially move the locking pin to an extended position and into a locking engagement with a slider member. In an alternate embodiment of the invention the first passage connecting the first hydraulic chamber with the socket is eliminated and instead the locking pin is modified to permit flow between second hydraulic chamber and first hydraulic chamber.
摘要翻译：用于可变地启动内燃机中的发动机气门的闭锁机构包括具有孔和插座的摇臂体。第一通道从插座引导到形成在锁销头上方的第一液压室。第二通道从插座引导到形成在锁定销头下方的第二液压室。由于第一和第二液压室都接受加压油，所以销轴的直径决定了将锁定销轴向移动到延伸位置并与滑动构件锁定接合所需的液压力。在本发明的替代实施例中，消除了连接第一液压室和插座的第一通道，而是改变锁定销，以允许在第二液压室和第一液压室之间流动。

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.

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 roller finger follower rocker arm assembly for deactivating an engine valve. A follower body pivots on a hydraulic lash adjuster, and engages a valve stem or lifter. The body receives a reciprocating member having a first and second rollers outboard of the body for following eccentrics of a cam lobe that straddles the body, the body having elongate openings on either side of the reciprocating member. A locking pin selectively locks and unlocks the body to the reciprocating member. The reciprocating member does not make contact with the cam lobe and functions only as a link between the latching mechanism and the rollers. The pin engages the reciprocating member by a latching spring and is disengaged by pressurized oil supplied through the hydraulic lash adjuster. Means is provided for limiting axial growth of the HLA during deactivation mode of the rocker arm assembly.

摘要： An actuating system for a mode-switching rocker arm device includes an elongate actuator shaft having a central axis that is parallel with and spaced apart from a central axis of an engine camshaft. An actuator lever extends in a generally radial direction from the actuator shaft to engage a locking pin of the rocker arm device. A cam follower engages and is pivotally oscillated relative to the central axis of the actuator shaft by an actuator cam lobe of the engine camshaft. A clutch/brake assembly is associated with the actuator shaft and the cam follower. The clutch/brake assembly is operable to selectively transfer pivotal oscillation of the cam follower to pivotal movement of the actuator shaft and actuator lever to thereby translate the locking pin and cause the rocker arm device to switch mode.

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 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. An elongate shaft extends through a transverse bore in the slider member and through a slotted passage in the slider member. In the follower body, the shaft is provided with bearings supporting first and second lateral roller followers on opposite sides of the body for variably engaging first and second preferably low-lift lateral cam lobes flanking the central cam lobe. A lost-motion spring urges the slider member into contact with the central 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 member slides within the follower body, allowing the lateral rollers to engage and follow the lateral cam lobes. Preferably, the latching mechanism is provided as a pre-assembled cartridge unit.
