A SERIES OF NOZZLES, OVERLAPPING ONE ANOTHER WITH A SMALL BUT MEASURED CLEARANCE BETWEEN ANY TWO TO ALLOW INWARED FLOW OF OUTSIDE AIR OR GAS, SO THAT A SMALL STREAM OF AIR OR GAS ENTERING THE FIRST NOZZLE AT HIGH PRESSURE CONVERTS ITS PRESSURE ENERGY INTO KINETIC ENERGY, SUCKS OUTSIDE AIR OR GAS AT EVERY JUNCTION OF THE NOZZLES ALONG ITS COURSE AND FINALLY LEAVES THE LAST NOZZLE AS A LARGE FLOW WITH LOW VELOCITY

摘要

1. An arrangement of nozzles in series, overlapping one another, placed coaxially either in a straight line or along a curve depending upon the need, with a small but measured clearance between any two consecutive nozzles, with separate annular enclosures covering the junction of every pair of nozzles, where such enclosures can individually be connected to separate sources of gas of air at high temperature and pressure and sequentially connected by valves to allow flow of gas or air in one direction as the entire arrangement is shown in the figure, and when such arrangement is connected to a source of compressed air or gas, a small flow of that enters the first nozzle, flows along the system, collecting more and more air or gas drawn from enclosures through the clearance between the nozzles and finally leaves the last nozzle as a larger flow with low velocity.
