Abstract
An electromagnetic valve has an armature () movable along an axial direction in a valve housing () as a reaction to current flowing through a stationary coil () and which at one axial end has a sealing member () designed to interact with a valve seat () assigned to a first valve inlet (P), wherein at least one second valve inlet and/or outlet (A, R) in the valve housing can be opened to the first valve inlet (P) by action of the armature, and wherein the sealing member is provided as sealing bodies () on a portion () of the armature of narrowed diameter, such that the sealing body having a larger diameter compared to the narrowed portion can be moved by movement of the armature between sealing positions formed at both axial ends of the sealing body, wherein the sealing body () is a component separate from the narrowed portion and/or releasable therefrom and has a sealing portion () made of a polymer and/or rubber material, and also a support portion () made of a material different than and harder than the sealing portion, and is designed for force-fit connection to the armature.
