Abstract: A method for calibrating a distance sensor of a rotary actuator device for controlling a charge cycle valve of an internal combustion engine. The rotary actuator device includes a controllable electric motor having an actuator element for actuating the charge cycle valve, two energy storage means acting in opposite drive directions on the charge cycle valve, a control and regulating device which controls the electric motor with regard to its rotor angle according to a stored setpoint path and a distance sensor for detecting the rotor position. At least one state variable of the electric motor is measured, the at least one state variable being compared with a reference variable. If there is a deviation between the variables being compared, the stored setpoint path and/or the distance sensor signal detected is/are altered as a function of the state variable.

Abstract: An engine valve driving device includes a rocker arm attached at one end to a valve stem and carrying at its opposite end a roller which engages the surfaces of a stepped cam plate. The cam plate has a horizontal surface which includes upper and lower portions joined by an inclined portion so that horizontal reciprocating motion operates the rocker arm and the connected valve. The cam plate is connected to a rotary cam crank shaft so that rotation of the crank shaft produces linear reciprocating motion in the cam plate. The connection between the cam shaft and the cam plate is adjustable, as by a hydraulic cylinder, to vary the gap between the cam plate and the cam shaft and to thereby vary the timing of the motion of the valve with respect to the rotation of the cam shaft. In an alternative form, the connection between the cam and the cam shaft may be a pivotal lever, with the pivot point of the lever being movable to provide timing adjustment.

Abstract: The invention concerns a valve drive system for an internal combustion engine, the valve drive system being provided between its at least one lifting valve (12) and its camshaft (34) in order to control the variable lift sequence. The valve drive system comprises a pressure-transmission arrangement which presses against the lifting valve (12), and a contact member (35) which abuts a cam (16) on the camshaft (34) and, as it changes position owing to the rotation of the cam (16), brings about an oscillating movement of the pressure-transmission arrangement. The pressure-transmission arrangement has a contact surface (80) via which pressure is transmitted. The contact surface (80), which can pivot about the bearing axis (14), comprises a first surface region (80.1) which has a circular-cylindrical curvature having the bearing axis (14) as the longitudinal axis of the cylinder, and a second surface region (80.2) which adjoins the first surface region (80.1) and has a non-circular-cylindrical curvature.

Abstract: Ledit dispositif comporte un engrenage rotatif à plusieurs éléments qui comprend un carter où est logée la soupape, une came tournante, reliée audit carter par une articulation tournante et dont l'entraînement provient du vilebrequin, un élément intermédiaire, actionné par la came via une articulation à came, et un élément de sortie, qui abute d'une part contre le carter via une articulation, qui coopère d'autre part avec l'élément intermédiaire via une articulation, et qui transmet le mouvement à la soupape. On obtient une structure plus rigide, plus simple à assembler et de dimensions moindres de la manière suivante: l'élément intermédiaire abute contre le carter via une articulation à came, la came de ladite articulation à came, agencée sur l'élément intermédiaire, comporte une section en encoche et une section de commande, et la position, soit de la came de ladite articulation à came, qui abute contre le carter, soit de l'articulation tournante de la came tournante, peut être modifiée pendant le fonctionnement du moteur.
