<p>1289464 Fluidic elements GARRETT CORP 9 Jan 1970 [15 Jan 1969] 1131/70 Heading G4P A bi-stable fluidic element has the power jet switched by control fluid applied to one or other of two sets of control nozzles. As shown each set comprises three nozzles 30-32, each set being fed from control ports 27, 28 via manifolds 26. The nozzles may have different widths. The use of multiple control nozzles allows the jet input pressure at port 13 to vary over a wide range without the need to adjust the control input pressure.</p> |
