Abstract : The requirements of an all-fluid pneumatic pressure regulator have been investigated and recommendations for a design have been made. The three major pressure regulator subsystem functions are (1) throttling, (2) feedback signal transfer, (3) reference, or error detection. The primary recommendation is that the throttling function be performed by a vortex valve supplied from a dual volume storage bottle. This represents the ideal all-fluid approach. The alternate recommendation is that throttling be performed with a vortex-controlled mechanical element. This avoids the volume penalty associated with the dual volume tank. With either approach, the feedback function can be performed with a circuit using confined jet amplifiers which combine a high supply pressure recovery with a low control to supply pressure ratio. A reference circuit distinct from the feedback circuit may not be required. (Author)
