Abstract

The invention relates to an electromagnetic device, in particular for a slip-controlled, hydraulic vehicle brake system, having at least a first magnet valve which is closed in its currentless basic position and having at least a second magnet valve which is open in its currentless basic position, the first and second magnet valves being received in receiving bores of a valve block. The invention provides that the first and second magnet valves have structurally identical, one-piece valve housings, in each of which all the magnet valve components are received essentially without any axial protrusion, and that the total length of each of the first and second magnet valves is recessed in the receiving bores of the valve block, and that a nonferromagnetic spacer ring is disposed between a face end, pointing toward the valve seat, of at least one magnet coil and a dividing plane between this magnet coil and the associated pole piece.
