Claim 1

A FLUID SUPPLY ASSEMBLY COMPRISING MEANS DEFINING A NOZZLE CHAMBER HAVING AN ORIFICE AT ONE END THEREOF, A FLUID SUPPLY CONDUIT COMMUNICATING WITH THE CHAMBER THROUGH AN INLET THEREIN ADAPTED TO IMPART A SWIRLING MOTION TO THE FLUID IN ITS PASSAGE TO THE ORIFICE, AND A SPILL CONDUIT COMMUNICATING WITH THE CHAMBER THROUGH AN OUTLET IN THE OTHER END THEREOF, MEANS FOR PUMPING FLUID THROUGH THE SUPPLY CONDUIT TO THE CHAMBER, VALVE MEANS IN THE SPILL CONDUIT FOR THROTTLING FLUID FLOW THERETHROUGH, MEANS FOR ADJUSTING THE THROTTLING ACTION OF THE VALVE MEANS, SAID THROTTLING ACTION GIVING RISE TO A VARIABLE PRESSURE DIFFERENTIAL BETWEEN THE SUPPLY AND SPILL CONDUITS WHEREBY THE FLUID OUTPUT THROUGH THE NOZZLE ORIFICE CAN BE VARIED OVER A PREDETERMINED RANGE, MEANS DEFINING A BYPASS CONDUIT SO INTERCONNECTING THE SUPPLY CONDUIT WITH THE SPILL CONDUIT AT A POINT INTERMEDIATE THE CHAMBER AND THE THROTTLE VALVE MEANS THEREIN AS TO SIMULTANEOUSLY COMMUNICATE THROUGH THE SPILL CONDUIT WITH BOTH THE THROTTLE VALVE MEANS AND THE CHAMBER SPILL OUTLET, AN AUGMENTING VALVE IN THE BYPASS CONDUIT, AND MEANS FOR CLOSING THE AUGMENTING VALVE, SAID AUGMENTING VALVE CLOSURE MEANS BEING RESPONSIVE TO A PREDETERMINED PRESSURE DIFFERENTIAL BETWEEN THE SUPPLY AND SPILL CONDUITS TO OPEN THE AUGMENTING VALVE AND PERMIT FLUID FLOW THERETHROUGH INTO THE SPILL CONDUIT, SAID PREDETERMINED PRESSURE DIFFERENTIAL BEING SELECTED SO THAT IN AT LEAST THE UPPER PORTION OF SAID OUTPUT RANGE FLUID FLOW THROUGH THE AUGMENTING VALVE IS GREATER THAN FLOW THROUGH THE THROTTLE VALVE MEANS, WHEREBY FLUID WILL FLOW THROUGH THE CHAMBER SPILL OUTLET AT A LOWER PRESSURE THAN AT SAID CHAMBER INLET.
