<p>1,247,920. Pure fluid amplifiers; fluidpressure servomotor system. GARRETT CORP. Nov. 26, 1968 [Nov. 30, 1967], No. 56076/68. Headings G3H and G3P. The output legs 20, 21 of an amplifier 11 are connected radially into vortex chambers 28, 29 which receive tangential control jets 36 from a source 37 to control the pressure in legs 20, 21 thereby differentially pressurizing chambers 40, 41 and moving actuator rod 43 to positions corresponding to the product of the control pressures exerted by source 37 and amplifier 11.</p> |
