ABSTRACT:
An electromagnetic actuator includes two electromagnets spaced apart from one another, an armature that is movable back and forth by magnetic force between the electromagnets against the force of two respectively counteracting springs, and setting means for adjusting the actuator to have a low energy requirement. To this end, the springs are pre-stressed such that the same energy is stored in both springs in connection with a maximum compression of the springs corresponding to the maximum stroke travel distance of the armature. The actuator is useful for actuating a valve to control the gas exchange in an internal combustion machine.
