Abstract
An electromagnetic valve device includes an armature body; a coil housing; a static, hollow cylindrical armature guide tube; and at least one electromagnetic coil interacting with the armature body and accommodated in the coil housing; the armature body being guided in the static, hollow cylindrical armature guide tube and can abut against a head part, which closes off the armature guide tube at the head side, of the armature guide tube extending through a central passage opening of the housing and through a central opening in a yoke disk at the base side as to the coil and at least partially engaging under the yoke disk by a radially outwardly projecting annular base part, in which, for axial support of the head part, the head part is at least partially engaged over by a coil housing support part that makes contact with the head part in a contact region.
