ABSTRACT:
A device for converting the rotation of a spindle nut into a force-related linear translation of a threaded spindle in an electromechanical valve actuator, the spindle being formed with longitudinal grooves in which clamping hooks are located. Hooked ends of the clamping hooks engage retainer rings of which one retainer ring abuts a collar on the spindle nut or abuts a stationary abutment, respectively, and another retainer ring restrains one end of a spring, the other end of which is restrained by a stationary abutment or the collar.
