Abstract
The present invention involves the insertion and use of a tube in one of the outlet channels of a pure fluid bistable amplifier. The amplifier will function so long as the cross-sectional area of the tube is less than twenty percent (20%) of the cross-sectional area of the outlet in which it is mounted. The advantage of the tube is that velocity-pressure recovery can be as high as eighty percent (80%) as compared to forty eight percent (48%) without it.
