ABSTRACT 



The development of a double leg elbow proportional fluid amplifier 

 to handle 5.85 gpm of water flow rate is described in detail. The ampli- 

 fier has linear output flow characteristics with a gain of 50 and can 

 switch flow from one output to the other completely. Based upon the 

 experimental results, analytical expressions are developed which clearly 

 show the effects of the active and passive legs flow parameters, the 

 control flow, and the size and location of the output ports on amplifier's 

 performance and they can be used in designing an amplifier of a desired 

 flow capacity. Analytical expressions to predict the performance of the 

 amplifier are also given. A mixing element comprised of two double leg 

 elbow amplifiers stacked together to mix two fluids was designed and 

 tested successfully.
