Abstract: A valve actuating cam has a periphery that can be varied in shape to control the opening and closing of one or more valves associated with a cylinder of an internal combustion engine. One portion of a valve assembly can be moved outwardly to change the valve lift. A band can surround the movable cam portion and cam body portion, and can form at least a major portion of the exterior surface of the cam that engages a cam follower such as a valve operating rocker arm. The timing of the opening and closing of one or more valves can be adjusted by adjusting the peripheral shape of the cam. The shape can be adjusted to start a ramp portion of the cam peripheral surface earlier to cause a valve to open earlier and to end a ramp portion later to cause the valve to close later with a first load on the engine and to open and close earlier when the engine is under a second load that is less than the first load. Wedges and wedging surfaces under the band and movable with the movable portion of the cam can be used to adjust the timing.

Abstract: A desmodromic valve system which provides direct bidirectional displacement of a valve stem of an internal combustion engine without the aid of a rocker arm, utilizing a semirigid basket operating in conjunction with a plurality of cams for each valve. The basket is disposed about the camshaft of the engine and secured to the valve stem by an integral retainer on a bottom portion of the basket, and is constrained to motion along the valve stem axis. The basket has a pair of downwardly oriented cam followers in the upper portion thereof, spaced apart from the valve stem axis. A central cam and a parallel pair of side cams are fixedly mounted on the camshaft so as to rotate therewith, the cams substantially surrounded by the basket and cooperating therewith to provide reciprocating valve action with positive bidirectional drive. The central cam is aligned with the valve stem axis, and the side cams are spaced apart from the valve stem axis, parallel to the central cam and respectively aligned with the cam followers. During a first part of a valve cycle, the central cam pushes the valve stem down so as to positively open the associated valve, and the valve stem pulls said basket down with it via the retainer. During a second part of the valve cycle, the side cams push the basket up via their respective cam followers and thereby cause the basket to pull the valve stem so as to positively close the valve.

Abstract: A method for calibrating a distance sensor of a rotary actuator device for controlling a valve of an internal combustion engine. The rotary actuator includes an electric motor with an actuator element for actuating the valve, two energy storage means acting on the valve in opposite drive directions, and a control unit for controlling the electric motor. The electric motor is controlled such that the valve is transferred from a first end position, in which the actuator element is a metastable torque-neutral position, to a second metastable torque-neutral position. Starting from a torque-neutral position, the electric motor is controlled such that the rotor is moved out of the torque-neutral position in at least one direction by a distance, and the resulting electric motor power consumption is measured. Depending on the electric motor current values, a new rotor position for calibration of the distance signal is ascertained.
