    摘要： The invention relates to a method for calibration of a positional sensor on a rotational actuator device for control of a gas exchange valve in an internal combustion engine. The rotational actuator device comprises a controlled electric motor with an operating element for operating the gas exchange valve, two energy storage means acting in opposing drive directions on the gas exchange valve, a control and regulation device, controlling the electric motor with regard to the rotor angle thereof relative to a stored set path, and a positional sensor for determining the rotor position. According to the invention, at least one status parameter for the electric motor is determined, the at least one status parameter compared with a reference parameter and, on a difference between the parameters for comparison, the stored set path and/or the recorded positional sensor signal are altered depending on the status parameter.

    摘要： An electromagnetic valve actuator system for controlling the operation of a valve in an internal combustion engine comprising a valve having a valve stem (42) with a valve head (44) at one end. The valve is reciprocable along the longitudinal central axis of the valve stem to alternatingly move the valve head between a first position and a second position. A first coil (51) is positioned on a first laminated core (52) having a gap and a thickness. A second coil (53) is positioned on a second laminated core (54) having a gap and a thickness. The gaps of the first and second cores are aligned. An armature (50) on the valve stem passes through the gaps of the first and second laminated cores, such that when the armature is centered in either of the gaps at least a portion of the armature extends slightly passed the thickness of the other laminated core.

    摘要： A valve (1) is urged in the valve-opening direction by an upper spring (24) and in the valve-closing direction by a lower spring (14). The valve (1) is thus urged to a neutral position where the respective urging forces are balanced. The valve (1) is controlled to be released from one of two terminal positions, that is, the full-open position or the full-closed position, and to be attracted to the position from which the valve (1) has been released. The displacement pattern of the valve during this period is sensed by a displacement amount sensor (42), whereby the maximum displacement amount of the valve (1) from that terminal position is measured. The change of the neutral position is detected based on the change of the measured maximum displacement amount with respect to a reference value.
