ACTUATOR FOR AN INTERNAL COMBUSTION ENGINE

ACTUATOR FOR AN INTERNAL COMBUSTION ENGINE

Known electromagnetic actuators comprising permanent magnets often have the disadvantage that returning the tappet is often not possible solely by way of permanent magnetic forces, when a distance of over 1 mm between the armature and core must be overcome. According to the invention, an actuator is...

Zusammenfassung:Known electromagnetic actuators comprising permanent magnets often have the disadvantage that returning the tappet is often not possible solely by way of permanent magnetic forces, when a distance of over 1 mm between the armature and core must be overcome. According to the invention, an actuator is proposed, in which the permanent magnet (32) is arranged in a stationary manner within the electromagnetic circuit (4) and means (34, 40) are designed for focusing axial magnetic field lines on the permanent magnetic circuit (8).
