Arrangement for actuating a charge cycle valve having an electromagnetic

Abstract

An arrangement is provided for actuating a charge cycle valve having an electromagnetic actuator which has an opening magnet and a closing magnet between which an armature is arranged in a coaxially displaceable manner which acts upon a valve stem. A spring acts upon the valve stem and is arranged between an upper driving element facing away from the charge cycle valve and a lower driving element facing the charge cycle valve. The driving elements are connected for joint movement with the armature. The spring is displaceable between an upper path boundary and a lower path boundary and is supported in the open position of the charge cycle valve in the upward direction on the upper driving element and in the downward direction on the lower path boundary. In the closing position of the charge cycle valve, the spring is supported in the upward direction on the upper path boundary and in the downward direction on the lower driving element. In the case of an approximately central position of the armature between the opening magnet and the closing magnet, one driving element respectively lifts the spring off the corresponding path boundaries. The armature has an armature tappet which is connected by way of a connection element with the valve stem.
