摘要： A system for selectively switching the action of a valve in an internal combustion engine includes a roller finger follower having a frame and a disengageable roller. A two-part axial pin for the roller axle is spring-loaded to urge the pin axially of the roller axle to disengage the first part of the pin from the follower frame and simultaneously disengage the second part of the pin from the roller axle. Thus the roller becomes detached from the frame and the follower cannot actuate its designated valve. The roller and pins are retained within the frame by at least one torsion spring. The pins may be controllably reinserted into the sides of the roller and frame to reconnect the roller to the frame by any of various electromechanical and/or hydraulic means. When used in conjunction with a camshaft having high lift and low lift cam lobes, the deactivated follower will then actuate its designated valve according to the profile of the low lift lobes, which may be a no lift profile.

The first and second side member define first and second pin orifices, respectively. A center roller is disposed between the first and second side members. The center roller defines a shaft orifice therethrough. A shaft extends through the shaft orifice. A first shaft end is disposed proximate the first side member, and the second shaft end is disposed proximate the second side member. The second shaft end defines a shaft bore therein. The first shaft end defines a pin chamber therein. The shaft bore being is substantially concentric with and intersects the pin chamber. A locking pin assembly is disposed partially within the shaft bore, the pin chamber and at least one of the pin orifices. The locking pin assembly has a first position wherein the shaft is decoupled from the body and a second position wherein the shaft is coupled to the body, and is switchable between the first and second positions.

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 system for continuously varying actuation of a valve in an internal combustion engine including a first cam for opening the valve, a second cam for closing the valve, and an oscillating rocker arm continuously engaging each of the first cam, the second cam, and the valvetrain, with the aid of a lost motion spring. The cams are disposed on first and second camshafts that are geared together. The first camshaft gear is driven by the engine crankshaft and thus is phase-invariant. The second camshaft gear is rotationally mounted on the second camshaft and supports the stator of a camshaft phaser. The phaser rotor is mounted to the second camshaft. Varying the rotor position varies the phase of the second cam and thus varies lift and closing timing of the valve. The system is useful in improving the performance of both spark-ignited and compression-ignited engines.

摘要： A deactivation roller finger follower for use with an internal combustion engine includes an elongate body. The body has a valve pallet end and a socket. The pallet end is configured for engaging a valve stem of the internal combustion engine. The socket is configured for engaging a hydraulic lash adjuster of the internal combustion engine. The body defines a roller aperture. A roller is disposed within the roller aperture. The roller is configured for engaging a cam lobe of the internal combustion engine. The roller defines a shaft orifice therethrough. An elongate shaft extends transversely through the shaft orifice. In a default operating position, the shaft is coupled to the body to thereby transfer rotary motion of the cam to pivotal movement of the body about the hydraulic lash adjuster. The shaft is selectively decoupled from the body such that the rotary motion of the cam is not transferred to pivotal movement of the body.

摘要： A two-step roller finger follower assembly for use in conjunction with a camshaft of an internal combustion engine, wherein the camshaft has at least one first lobe and at least one second lobe. The roller finger follower assembly comprises a follower body for engaging the first cam lobe and having a central aperture, a follower pivotably disposed on the follower body in the central aperture for engaging the second cam lobe, and a limiting stop disposed on the follower body for engaging a feature on the follower to limit travel of the follower body with respect to the follower. The limiting stop prevents overtravel of the follower body during valve-deactivation mode of the assembly, thus preventing excessive leak down of an associated hydraulic lash adjuster.

摘要： A mechanism for compensating systematic uni-directional torque bias imposed on a bi-directional drive actuator shaft, comprising a pallet disposed on an arm for rotation with the actuator shaft. A bucket tappet is engaged by the pallet and contains a helical compression spring. As the actuator shaft rotates and compresses the spring, the load on the pallet increases linearly but the length of the lever arm changes non-linearly at a rate different from the force applied to the pallet. This results in a non-linear torque about the actuator shaft. The torque can be the same at the compression spring preload state as it is at the full load state or it can be biased to be unsymmetrical based on the layout and size of the components and the stroke of the actuator shaft.

摘要： A two-step roller finger follower having a movable high-lift portion and a low-lift portion. A lock pin mechanism in the low-lift portion includes a lock pin that may be driven hydraulically into latched engagement with the high-lift portion. The lock pin assembly comprises a lock pin and a separable switching pin. A blocking clip mountable on the associated hydraulic lash adjuster includes first and second ends that extend into a switching pin locking groove to block axial motion thereof. A ramp on the follower body mates with a ramp on the blocking clip such that oscillatory motion of the follower engages and disengages the blocking pin from the locking groove. The clip unblocks the switching pin at only those times in the camshaft rotational cycle when complete locking and unlocking is assured, and ending well before the beginning of the next valve lift event.
