1. An electromagnetic valve comprising:
an electromagnet having at least one magnet coil;
a magnet armature;
a pole core;
a magnet yoke;
a housing which closes the electromagnet; and
a valve assembly having a valve sleeve; a valve slide;
and a restoring spring;
wherein the valve assembly being enclosed in its axial extent by the housing;
wherein the pole core includes an outer magnetic pole and the valve sleeve which is enclosed by the outer magnetic pole, at least two fluid ducts running in an axial direction between the valve sleeve and the outer magnetic pole in zones which are delimited in a fluid-tight manner on a circumference of the valve sleeve and/or within the outer magnetic pole;
wherein the valve sleeve having at least two transverse bores or other cavities which run perpendicularly with respect to a center axis of the valve sleeve and are connected fluidically to the at least two fluid ducts and interact with the valve slide in a manner which is dependent on an axial position of the valve slide;
wherein the magnet armature is radially mounted firstly in a bearing and secondly by way of a slide head of the valve slide, the magnet armature making contact by way of a conical face with the slide head, and it being possible for radial forces to be transmitted from the magnet armature to the slide head.
