  • the invention relates to an electromagnet consisting of a coil to which current can be applied, which is such a magnetic field generated and moved an armature when current was applied, and the armature for driving a valve or one serves other element, the movement of the armature of one or more damping elements is damped.
  • the aforementioned electromagnets have one in the field of technology widely used. They are used, for example, in textile machines for a quick weft insertion of the threads.
  • electromagnets described above are also used for Control of gaseous and liquid media (especially in Liquid or hydraulic circuits), for example in one Valve or as an actuating or lifting magnet for lifetime and time-critical applications.
  • Electromagnets Especially the area of application in weaving machines or other Textile machines require high performance from Electromagnets. It is expected that the electromagnet achieve the highest service life requirements and switching frequencies. This results in considerable mechanical loads for the electromagnet and the movably mounted elements.
  • German patent 31 32 396 there is an electromagnet described the elastic elements as a damping body uses the kinetic energy of the anchor and thus prevents premature wear of the electromagnet.

There are not any increased requirements regarding the surface quality of the Tube to take into account more because this task of the plastic tread, especially of the inserted film, is taken over. The solution according to the invention thus leads to a less expensive structure and easier assembly of the device.

So far, magnets that have too large a dimensional tolerance, automatically one Reject piece because the air gaps are too large the efficiency or limited efficiency of this device and thus this device can no longer be used for certain applications was. Because the movable anchor on a plastic sliding surface slides, the thickness of this surface can be adjusted so that optimal conditions prevail. When testing the devices can thus be made by an appropriate choice of film thickness Dimensional tolerances in production are compensated for. This Preference is also repeated when the devices are overhauled.
