Abstract

1311111 Jet pumps P B M LITTLE [trading as HOLYWELL ENG CO] 1 July 1971 [4 April 1970] 16050/70 Heading F1E An injector comprises an annular inducing air chamber 3 fed from a pipe 1 which is divided into two pipes 2 which enter the chamber tangentially. The area of the inducing fluid nozzle 5 is variable by axial adjustment, by means of screws 6, of the induction pipe 4 the end of which is open to atmosphere.
