valve and enable the careful reduction of the kinetic energy that was released by the closing process without mechanically overloading linear unit 6 shock absorbers 6 4 provide a speed dependent braking function which upon standstill does not develop any remaining force so that energy storing spring 6 2 will press with its pretension in the closed state on the steam valve seat and keep the steam valve closed against any possibly occurring steam power now additionally referring to fig2 there is shown an embodiment of an electromechanical drive 1 in accordance with the present invention in an extending configuration which in the case of a quick action closing closing a steam valve not shown by a retraction direction of movement in contrast to fig1 the displacement of piston rod 6 3 is supported by energy storing spring 6 2 in such a way that energy storing spring 6 2 supports piston rod 6 3 in its retracting direction which means that the free end of piston rod 6 3 is pulled by spring force of energy storing spring 6 2 in the inside direction of drive 1 accordingly shock absorbers 6 4 are positioned to be adjacent to gearing 5 now additionally referring to fig3 there is shown an embodiment of an electromechanical drive 1 in accordance with the present invention according to fig1.
