<p>The emergency actuator comprises a lifting system arranged inside a pressure spring so that the large spring force can be electromagnetically held by a much smaller spring force. The triggering process is carried out with very little friction and a high spring force to holding force is produced. Preferred Features: The spring force of the pressure spring is receive by two toggle levers (7, 8), in which the lower lever is hinged on a central mandrel (2) connected to an upper spring plate (18) using a pin (21) and the upper lever (7) is hinged on a toggle lever bridge (10) and screwed to a lower spring plate (11).</p> |
