Zusammenfassung:The invention relates to an electromagnetic valve with armature means (22) which are designed to be movable along an axial direction in a valve housing (14) as a reaction to current flowing through stationary coil means (16) and which at one axial end have sealing means (28) designed to interact with a valve seat (32) 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 means, and wherein the sealing means are provided as sealing bodies (28) on a portion (26) of the armature means of narrowed diameter, such that the sealing body having a larger diameter compared to the narrowed portion can be moved by the movement of the armature means between sealing positions formed at both axial ends of the sealing body, wherein the sealing body (28) designed as a component separate from the narrowed portion and/or designed to be releasable therefrom has a sealing portion (42), made of a polymer and/or rubber material, and also a support portion (40) which is made of a material different than and in particular harder than the material of the sealing portion, and which is designed for force-fit connection to the armature means.
