Electrofluidic converter

Abstract

The converter includes a pressure fluid operated, bistable fluidic element, n the form of a fluid oscillator, having a pressure fluid supply inlet opening into an interaction chamber, two outlets extending downstream from the interaction chamber to the exterior and diverging in direction at an acute angle, two control inlets communicating with the interaction chamber, and a magnetic system actuated by electric input signals and influencing the control pressure in the control inlets to deviate the pressure fluid from one outlet to the other outlet. Respective feedback conduits are branched from the outlets to respective associated control inlets. Valve arrangements are selectively actuable by the magnetic system to close or open the feedback conduits. In one embodiment of the invention, a single valve is provided in the form of an armature of the magnetic system. In another embodiment of the invention, each control inlet has a respective valve therein in the form of an armature of the electromagnetic system. In each embodiment, the valves open in the direction of fluid flow through the feedback conduits. Fluidic capacities may be connected to the feedback conduits, and the control inlets may be connected to a pressure source through loading conduits.
