OSTI ID:6342479
This patent describes a pressure regulator. It comprises: a body having a fuel inlet, a fuel outlet, an air inlet, an air outlet, a spill passage connecting the fuel inlet to the fuel outlet, a spool valve controlling flow through the spill passage, a linear motor having a coil and an armature, a stem connecting the armature to the valve to position the valve to control flow through the spill passage and thereby to control the fuel pressure in the inlet as a function of the current in the coil, a piston subjected to the pressure in the fuel inlet, the piston defining a variable orifice adapted to create a reference pressure at a desired differential from the pressure in the fuel inlet, a diaphragm subjected to the reference pressure and the pressure in the air inlet, and a valve positioned by the diaphragm to control flow from the air inlet to the air outlet.
