Abstract: A system for metering fuel to an engine. The system includes a fuel metering valve having a throttled inlet and a throttled outlet. The system also provides regulation of redundant pump supplies of fuel to the engine. The throttling of the inlet to the fuel metering valve is provided by a valve that also functions to selectively couple a second fuel pump to the fuel metering valve.

Abstract: An electrical actuator is particularly suited for driving a wellhead valve for regulating the flow of natural gas from a production well. The electrical actuator can be driven using the existing local power supply in wellhead valve systems, typically a solar panel and a battery. The electrical actuator may include a gear reduction train, a brake and a manual input override with clutch protection. The electrical actuator can be configured in three different operational modes that provides a predetermined position upon power loss including fail-bias fixed, fail open and fail bias closed.

Abstract: A dual-supply fluid distribution system includes a first pump having an inlet and an outlet. The first pump is configured to supply a first fluid flow. A second pump has an inlet and an outlet, and is configured to supply a second fluid flow. A check valve is coupled between the first and second pump outlets. The check valve is configured to combine the second fluid flow with the first fluid. A bypass valve is coupled to the outlet of the first pump. The bypass valve has an integral pilot valve and is configured to permit fluid flow from the pump outlets in excess of the fluid demand to recirculate back to the first and second pump inlets. The bypass valve and integral pilot valve are configured to cause the check valve to open when the flow of fluid through the bypass valve is below a threshold amount.

Abstract: A common regulator valve is provided for a variable displacement pump fuel metering scheme in which the common regulator valve both controls working output to a pump actuator to control displacement of the variable displacement pump and also to control bypass of excess fuel flow. The regulator valve also includes a differential piston which generates a compensation force off of the bypass flow in order to compensate for changes in spring force and flow reaction force at different system pressures and operational states. As a result, errors in the metered fuel flow can be either eliminated or substantially reduced.
