Abstract
A pressure regulator that has a geometry that reduces regulator droop is provided that reduces or eliminates the need for a larger package size for a given set of flow requirements. The regulator comprises a housing having a fuel inlet port and a fuel outlet port; at least one regulation stage having an input in fluidic communication with the fuel inlet port; a final regulation stage comprising an inlet in fluidic communication with an output of the at least one regulation stage, a mating valve seat in fluidic communication with the inlet, and a valve seat in movable contact with the mating valve seat, the valve seat having a bottom having an edge, the edge having means for reducing regulator droop; and means for moving the valve seat from a closed position to an open position in response to a pressure change. The means for reducing regulator droop comprises a reverse lip or an approximately square edge.
