1,186,661. Pure fluid amplifiers. CORNING GLASS WORKS. Jan.18, 1968 [Jan. 26, 1967], No. 2764/68. Heading G3H. A fluid amplifier has a pair of identical parallel connected amplifiers 12, 13 arranged back to back with a common power source 40 feeding inlets 16, 16<SP>1</SP>, and common outlets 38, 39 connected with output channels 22, 23 of the respective amplifiers. Connections 34, 35 in cover plate 14 provide fluid to control channels 20, 21 and similar control fluid inlets 41, 42 are provided in cover plate 11. Vents 24, 25, 26 and 27 are also provided in each amplifier. The Specification states that for input pressures A, B, C and D, and output pressures E and F in amplifiers having gain n:- If (A-B)>(D-C)thenF>E by n[(A-B)-(D-C)]. In a modification (not shown) the amplifiers operate digitally. |
