A fuel control system is provided in a single compact modular unit. The unit includes a motor driving a highly accurate cam-operated double-acting piston metering pump, both of which are contained in a liquid fuel environment. As the liquid fuel is pumped it works to cool internal components including the motor. An electronic motor drive is contained in a dry chamber of the unit for controlling operation of the motor and pump and is cooled indirectly by the fuel as well. A pressure sensitive flow divider is also included for selectively providing one or multiple output fuel flow paths depending upon whether a pressure threshold is reached, for example to send fuel to primary and secondary burner nozzles. Filter, filter bypass, pressure relief, and fuel shut-off components are also integrated into the single modular unit.
A fuel control module for controlling the flow of fuel from a fuel supply to a fuel consuming device having at least two consumption components, the fuel control module comprising a housing having an inlet and an outlet, including a first outlet port in communication with a first of the consumption components and a second outlet port in communication with a second of the consumption components, and containing a drive section, a pump section and a flow divider section, the drive section including a motor and an electronic motor drive, the pump section having an operating member moved by the motor in response to a signal from the motor drive to effect flow of fuel between the inlet and the outlet of the housing, the flow divider section having first and second passageways in communication with the respective first and second outlet ports and having a valve controlling fuel flow through the first passageway such that when the valve is closed fuel is directed only to the second outlet port for delivery to the second consumption component and when the valve is open fuel is directed to both the first and second outlet ports for delivery to the respective first and second consumption components, wherein the housing includes a filter section having a filter element disposed in communication with the inlet of the housing and the pump section and a filter bypass valve which opens to allow fuel flow from the inlet to the pump section without passing through the filter element, wherein the filter bypass valve is asymmetric having an enlarged downstream end such that it is pressure activated to open when sufficient pressure acts on the enlarged end.
