Multistage Hydraulic Fluid Amplifier Characteristics.

Abstract

Characteristics of laminar, proportional fluid amplifiers have been measured for operation on hydraulic fluid. Single stage blocked load gains as high as 15--20, dynamic ranges exceeding 1000 and frequency responses above 200 hertz were measured. Multistage amplifier preliminary design guidelines are formulated and illustrated with the design of a three-stage power amplifier. For the three-stage amplifier, a pressure gain of 375 and a first-stage to third-stage supply nozzle power gain of 825 were measured. The amplifier frequency response has less than 90 degrees phase shift at 100 hertz.
