Abstract
A fluidic flow control device includes at least three terminals with two of the terminals being connected to input nozzles opposing each other in axial alignment. An interspace is provided adjacent the point of intersection of the two streams from the nozzles and a radial diffuser is provided encircling the interspace. The third terminal communicates with the radial diffuser. The variable relationship between the flows produced at the nozzles is effective to control the flow at the third terminal. The diffuser is formed by planar faces separated by a constant width gap. The gap opens into an annular plenum to which the third terminal is connected. The entry area to the radial diffuser is sized to be substantially equal to the sum of the areas of the nozzle throats. In one embodiment, a mixer region may be provided between the diffuser and at least one of the nozzles. A fourth terminal acting as a vent may communicate with the mixer region. If desired, a second radial diffuser may be provided and one nozzle throat may be larger than the other. A partition may be provided in the diffuser.
