ABSTRACT:
A burner control system comprises a housing defining a reservoir therein and primary and secondary pumps disposed in the reservoir for pumping oil through a viscosity valve and into a burner. The outlet side of the primary pump communicates pressurized oil to the inlet side of the secondary pump directly via intercommunicating conduit means. A back pressure valve communicates with the conduit means to substantially equalize the oil pressure between the inlet and outlet of the secondary pump, discharging the excess oil capacity back into the reservoir.
