Abstract:
1. A method for controlling a valve having a spring with a spring force, an actuator with an actuator force that counteracts the spring force, and a pin coupled to the spring and which can be actuated by the actuator, the method comprising: applying to the actuator a current having a predefined profile proceeding from a starting value of the current, at which the pin is in a starting position in which the pin allows movement of a de-energized valve between open and closed positions, wherein the predefined current profile includes at least one section, each section defining: a starting current value, a final current value that is lower than the starting current value, a first time interval with a continuously falling current profile, and a subsequent second time interval with a continuously rising current profile, and wherein after the predefined profile of the current is passed through, the pin is in an end position in which the pin prevents movement of the de-energized valve between the open and closed positions.
