A hydraulic slide valve with electromagnetic actuation is proposed, the magnet armature of which is embodied by a hollow-cylindrical tube element. The lower bearing location of the magnet armature is provided by the slide of the hydraulic valve, which with a corresponding step engages the inner bore of the armature; the upper bearing location is embodied by a slide element attached to a stationary cover plate.

A hydraulic, electromagnetically actuated slide valve for electronic transmission control means, comprising a housing, an electromagnet in said housing including a carrier, a winding on said carrier, and a magnetic armature operative in said winding, a valve slide in said slide valve, said valve slide including a protrusion on one end thereof, characterized in that said magnetic armature is a hollow-cylindrical tubular element having an inner bore that forms an upper end bearing and a lower end for slidably supporting said magnetic armature via a slide element, said lower end of the magnetic armature is effected by means of an engagement with said valve slide to act upon said valve slide which is slidably guided in an associated valve bearing block of said slide valve to adjust said valve slide in said slide valve, and said magnetic armature is supported at one end by the inner bore of the armature and said protrusion on said valve slide without any relative displacement between said magnetic armature and said valve slide during movement of the magnetic armature, a compression spring applies a force on one end of said valve slide which holds said valve slide and said armature together in axial alignment, an enclosure cap for said housing, said slide element being disposed in a stationary manner on said enclosure cap, said slide element including an associated bearing slide portion which engages the inner bore of the armature for slidably supporting said magnetic armature.
