Abstract

1431810 Ejectors with coanda nozzles SRC LABORATORIES Inc 18 June 1973 28903/73 Heading F1E In an ejector having a coanda inlet nozzle 14 and a throat 23 of substantially no axial length, the ratio of the diameter of the throat A to the axial distance E between the throat and the nozzle 14, A is greater than substantially 3, and the ratio of the diameter E C of the nozzle to A, C/A is greater than 1.5. Other preferential dimensions are given.
