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 valve train system includes a camshaft with a camshaft lobe that is rotatable about a camshaft axis. A control shaft is rotatable about a control shaft axis and includes an eccentric control shaft slot. An input rocker engages the camshaft lobe and has a rocker slot. An output rocker engages a valve actuation member which is engaged with a combustion valve. A rocker pivot shaft has a rocker pivot shaft axis and is fixed to the output rocker and extends through both the control shaft slot and the rocker slot. Rotation of the camshaft causes the input rocker and the output rocker to pivot about the rocker pivot shaft axis and rotation of the control shaft changes the magnitude that the input rocker and the output rocker pivot about the rocker pivot shaft axis and also changes the magnitude of opening the combustion valve.

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.

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 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 lock pin bore in a two-step rocker arm assembly contains a hydraulically-actuable lock pin. A return spring urges the lock pin toward an unlatched mode. The bore has one or more annular grooves formed near the outer end of the bore. A plug, formed preferably of a soft metal, is pressed as a hydraulic seal into the bore. During assembly, the final position of the lock pin within the bore is set by positioning a stopping assembly fixture into the locking end of the bore. The plug is pressed into the bore until contact is made with the lock pin and the lock pin engages the fixture. The plug is radially deformed into the annular groove(s) to anchor the plug and fix the outer limit of travel of the locking pin and the compressive load on the return spring.
