摘要： The invention relates to an electromagnetic control device comprising at least one electromagnet and a displaceably mounted armature which can move back and forth between pole faces by electromagnetic force. Said armature is kept in an intermediate position without activation of the winding of the at least one electromagnet by two opposing spring forces. Once the armature reaches an end position it remains close to the pole faces of the electromagnet by a lower magnetic force. At least one of the electromagnets has a divided winding which can be mounted in various circuits.

摘要： A method for controlling electromagnetic actuators for operating induction and exhaust valves in internal combustion engines where one actuator (1,40), connected to a control unit (10), is coupled to a respective valve (2,41) having a real position (Z) and includes a movable element (3,42) magnetically driven by means of a resultant force (F) to control the movement of the said valve (2,41) between a closure position (Z SUP ) and a fully open position (Z INF ); the control unit is further connected to a piloting unit (15) and includes a supervision block (11), an open loop control block (12), a closed loop control block (13) and a selector block (14) commanded by a switching signal (SW) generated by the supervision block (11). The method includes the steps of: operating in an open loop control mode of the real position (Z); operating in a closed loop control mode of the real position (Z); and alternatively selecting the open loop control mode and the closed loop control mode.

摘要： The invention relates to a drive unit for a valve of an internal combustion engine. According to the invention, a pivotably mounted lever which is moved in a reciprocating manner acts on the valve stem. The pivoting movement is produced by means of a torque motor whose axis of rotation matches the pivot axis of the lever. The rotor of said torque motor is connected to the lever in order to transmit the rotating movement.

摘要： Method for regulation of currents during phases of stoppage in electromagnetic actuators, in which an actuator (1) is connected to a valve (2) and includes a mobile unit (3), a sensor (12) and a first and a second electromagnet (6a,6b), which receive respectively a first and a second current (I SUP , I INF ); the mobile unit (3) being disposed in a position of stoppage (Z SUP , Z INF ) during phases of stoppage. The method includes the phases of: setting (100) at least one current (I SUP , I INF ) out of the first and the second currents (I SUP , I INF ) to an initial maintenance value (I HO ), when the valve (2) is in a position of stoppage (Z SUP , Z INF ); checking (120) that the valve remains in a position of stoppage (Z SUP , Z INF ) for a pre-determined interval of time (ΔT); and decrementing (170) the current (I SUP , I INF ), if the valve has remained in a position of stoppage (Z SUP , Z INF ) for the pre-determined interval of time (ΔT).

摘要： Disclosed is an electromagnetic drive, comprising an armature that can move electromagnetically back and forth. An element, especially the valve of an internal combustion engine, is driven by the movement of the armature. The ratio of the depth of the yoke in relation to the width of the yoke of the electromagnets and the length of the armature in relation to the width of the armature is greater than 1.5, preferably greater than 2, in order to reduce the power consumption of said drive.

摘要： The invention relates to an actuating drive for a valve of an internal combustion engine in which a lever which is actuated is pivotally mounted and rests on the valve stem directly or via a force transmitting element. The area of action of the lever on the stem lies outside of the effective range of the electromagnets, the armature represents only a portion of the pivotal lever, and the valve stem comprises an alternative element for a portion of the valve stem beyond the axis of the valve.
