ABSTRACT:
Described herein is a flueric laminar bi-stable amplifier. The device comses essentially a flueric amplifier having a supply nozzle, a pair of outlet nozzles, a pair of control nozzles, vent means located along the axial path of fluid flow and means for providing a supply of pressure to the vent means so as to maintain the vent pressure above ambient pressure. Means are also provided for grounding the control ports and for providing back pressure to the control ports. Essentially, the device is a flueric laminar flip-flop that does not use the Coanda effect, but rather it relies upon the instability of jet position due to vent pressurization. If vent flow is allowed to enter the control region in excess of that demanded by entrainment and the control port is vented to ambient, then any small perturbation will cause more flow to enter one side and less on the other, thereby increasing the pressure differential and causing the jet to deflect more until it reaches a stable position on one side or the other.
