ABSTRACT:
An electro-fluid converter for controlling a fluid actuating an adjusting element, such as a main control slider of a servo valve, comprises at least one displaceable throttle arranged in a fluid-rich circuit. The throttle has at least one throttle element with a central inlet passage and a plurality of flow-mechanical identical base elements arranged around the central inlet passage in a star-like manner. Each of the base elements includes a bipolar wall stream element connected with the inlet passage and a whirling chamber element connected with the wall stream element, each of the wall stream elements being thermoelectrically controllable.
