Abstract
The invention is an electromagnetic actuator with a magnet coil arranged in a housing and with an armature plate, which is movable by energization of the magnet coil in an armature plate space in the direction of a front end of the housing and which is connected to an armature plunger, which at one end is guided through the housing and protrudes into a control space; according to the invention the armature plate is formed with at least one axial pressure compensation bore so as to produce pressure compensation between the armature plate space and the control space, and the housing has at least one bearing with at least one axial groove, in which the armature plunger is mounted movably.
