Electromagnetic actuating device

An electromagnetic actuating device for a valve comprising:

• an armature axially movably situated between two axial stops, an armature chamber being delimited by a magnet yoke;
• an electrical coil coaxially encompassing the armature in the magnet yoke, and the magnet yoke being at least partially situated in a housing;
• the armature having a cylindrical geometry including a base remote from the housing and, axially diametrically opposed, a hollow cylindrical end section, the base being connected to an actuating plunger, a guide sleeve being axially fitted onto the hollow cylindrical end section, and an anti-adhesion device being situated or formed at an end of the guide sleeve remote from the actuating plunger, preventing or at least impeding an axial adhesion of the armature to the magnet yoke,
• wherein the anti-adhesion device at the end of the guide sleeve remote from the actuating plunger is formed by a radially inwardly directed, at least in sections, circumferential contact section having at least one elevation facing away from the armature,
• the at least one elevation being a ring-shaped elevation extending axially in a direction of a base of a first magnet yoke segment near the housing, the first magnet yoke segment having radially inside a cup-shaped geometry forming an armature chamber for axially movably accommodating the armature.
