<p>1,241,145. Pure fluid proportional amplifiers. BENDIK CORP. Dec.29, 1969 [Jan.27, 1969], No.63104/69. Heading G3H. The entry portions 60, 62 of the output channels 26, 28 of a proportional amplifier are flared, as shown, to inhibit the sharp cut off of output pressure which results from saturating a conventional amplifier. Figs. 2 and 4 (not shown) illustrate the output/control pressure characteristics of amplifiers with and without flared entry portions 60, 62.</p> |
