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

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.

[ The embodiments of an invention in which an exclusive property or right is claimed are defined as follows:] [1.] In a device for converting rotation of a spindle nut into a force-related linear translation of a threaded spindle, the spindle nut at its limiting position in each of opposite directions exerting a displacement force against a spring which spring is compressed between a stationary and a displaceable abutment, the improvement which comprises:a spindle nut having a plurality of longitudinal grooves spaced around its circumference;a spring;a plurality of clamping hooks respectively located in said plurality of longitudinal groves; andengagement means linking said spring and said clamping hooks so that opposite ends of said spring are alternatively displaced depending on the direction of force exerted by said spindle nut.
