Abstract

A method for is provided actuating at least one electromagnetic valve containing at least one coil, which can be excited by an excitation current, and an armature, in which the excitation current can be set such that, in response to a signal for actuating the armature from one position into another position, it causes the actuator to move as a result of an excitation current threshold being exceeded, and is kept at a value which is lower by comparison in order to hold the armature in a specific position. The excitation current, which is greater than zero but below the excitation current threshold, is applied at least temporarily to the electromagnetic valve even if no signal for actuating or for holding the armature is present.
