Abstract
A dual range dynamic pressure differential generator for use at low pressures using a differential over a variable valve for a first stage pressure differential and the differential over a flow accelerator for a second stage pressure differential. The differential over the variable valve is useful for higher pressure differentials while the differential created over the flow accelerator is useful for a lower range pressure differential, although the two ranges may overlap.
