  • Linear electromagnetic drive means
    Patent number: 5521446
    Abstract: A linear electromagnetic drive means comprises a coil with a controllable electric current flowing therethrough, magnetic poles assigned to the coil and an axially displaceable core biased by at least one spring in the region of the coil and the magnetic poles, whereby the core serves to control a control element by means of its displacement movement triggered by the electric current. The spring biasing the displaceable core has the design of a tube in which slits extending essentially radially are formed with flexible tube segments lying therebetween.
