Abstract: The amplifier includes a supply jet providing fluid to an interaction chamber and a pair of fluid outlet passages on the side of the chamber opposite the supply jet. A pair of control nozzles are provided on laterally opposite sides of the supply jet for deflecting the jet into one or the other of the outlet passages. A pair of supplementary nozzles in communication with the fluid supply are also located on opposite sides of the supply jet. The flow resistance through the supplementary nozzles is large so that as the jet is deflected by flow through the control nozzle, the supplementary flow increases due to decreased resistance and increases its support of the pressure field deflection. Accordingly, the control flow has a high input impedance requiring little control flow.

Abstract: A pure fluidic strain gage is disclosed which comprises a conduit or duct constructed of deformable material through which a fluid is caused to flow. The conduit is adapted to receive an external stress and be deformed thereby in a predetermined manner such as by a change in length or the like of the conduit. This deformation produces a change in fluid resistance in the channel and thus effects a variation in the flow characteristics of the fluid through the conduit. A monitoring device, such as a fluidic proportional amplifier, is provided to detect such variations in flow characteristics, these variations being indicative of the value of the external stress received by the conduit and the strain of the conduit.
