Abstract (en)
[origin: WO2017137119A1] The invention relates to a method for controlling an electromagnetic adjustment unit (1) with an annular magnetic coil (2) and with an armature (5), which is able to execute a stroke motion between a first and a second end stop (3, 4) in order to actuate a valve piston (6) of a valve (7), in particular of an electromagnetically actuatable suction valve, in which method a magnetic force is generated by energization of the magnetic coil (2), by means of which magnetic force the armature (5) is drawn in the direction of the second end stop (4) counter to the spring force of a spring (8). According to the invention, the speed of the armature (5) before reaching the second end stop (4) is reduced, within a predefined switching time, by varying the energization profile and/or the electrical voltage present at the magnetic coil (2).
