Electromagnetic actuator

An electromagnetic actuator, comprising:

• a magnetic coil, which has a coil form and a coil winding situated on the coil form, wherein the coil form has a central clearance extending in an axial direction;
• an armature slidably situated in the central clearance;
• a terminal piece situated on an axial end of the coil form;
• and
• an actuating element supported in the terminal piece, the actuating element being slidable in the axial direction of the coil form;
• wherein the armature is configured to be movable by an actuation of the magnetic coil such that a force applied by the armature of the electromagnetic actuator is transmitted to the actuating element, and wherein the actuating element is configured in two parts and has (i) an actuating pin supported in the terminal piece and (ii) a separator which is connected in a fixed manner to the actuating pin on an end section of the actuating pin protruding from the terminal piece in the direction of the armature and on which the armature acts when the magnetic coil is actuated,
• wherein the separator is made of a non-magnetic material,
• wherein the separator is configured in the form of a cup,
• wherein the actuating pin is inserted by the end section protruding from the terminal piece in the direction of the armature into the cup-shaped separator,
• wherein the cup-shaped separator is one of pressed or shrunk onto the actuating pin, and
• wherein the cup-shaped separator has a cylinder sleeve, a bottom, and, on an end facing away from the bottom, a laterally projecting collar which limits the maximum displacement path of the actuating pin in the terminal piece by making contact with one of the terminal piece or a component connected to the terminal piece when the separator is acted upon by the armature.

• a pole tube inserted into the central clearance of the coil form, wherein the pole tube has at the outer circumference a clearance, the armature is slidably supported in the pole tube, and an end of the pole tube facing the armature on the side of the terminal piece has a yoke configured as one piece on the pole tube, and wherein a through hole is provided in the yoke, the diameter of the through hole being dimensioned in such a way that the separator is movable back and forth in the through hole.
