Patent ID: 8348630

Claim:
A fuel supply system, comprising: a variable displacement pump providing a high pressure fuel supply from a fuel sump; a displacement control device controlling displacement and thereby pump output of the variable displacement pump; a fuel metering valve fluidically connected to the variable displacement pump for receiving the high pressure fuel supply and metering fuel flow flowing toward a combustion chamber; a regulator valve including a valve housing and a valve element movable therein, the regulator valve having in combination a fuel bypass arranged within the valve element to bypass a portion of the high pressure fuel supply around the fuel metering valve and a working output acting upon the displacement control device, wherein movement of the valve element simultaneously regulates the fuel bypass and the working output, the moveable valve element responsive to a pressure differential across the fuel metering valve; and a compensator integrated into the regulator valve deriving a compensation force from fuel flow through the fuel bypass within the valve element, wherein a position of the moveable valve element is determined, at least in part, by the compensation force and the pressure differential across the fuel metering valve.
