Electrically controlled actuating device

摘要

An electrically controlled actuating device for mechanically moving a component, in particular an actuating device for an aileron of a missile, is intended to produce considerable actuation forces, set specific movement paths and be of compact design. For this, an electrical control voltage is applied to a piezo element, the end of which which is displaced as a function of the control voltage is attached to a piston. The piston is guided in a cylinder of a closed fluid circuit. Arranged in the fluid circuit is a further piston which is connected to the component to be moved. <IMAGE>
