Abstract
A solenoid, in particular for switching pressure controllers or pressure valves, including an armature movable in an armature space, and a coil which can be impinged by current. When the coil is impinged by current, a magnetic field is generated serving for moving the armature, and the armature space can be filled with oil. For de-airing the armature space at least one de-airing channel is provided. In the de-airing channel at least one backflow-preventing element is provided which is permeable in the direction of de-airing.
