  • Variable throat nozzle
    Patent number: 3942724
    Abstract: A nozzle having a through passageway in which the flow of pressurized fluid induces the flow of secondary fluid therethrough with the passageway having a throat that is adjustable in cross-sectional extent to enable the nozzle to efficiently operate over a wide range of operating conditions. The throat extent may be automatically changed with a change in the operating condition within its range or as in one embodiment be easily set for one operating condition.
