Abstract
A relief valve is built into the nozzle port of a fuel pump for an oil burner and opens to relieve pressure in the fuel supply line and prevent oil from dripping out of the burner nozzle when the pump is shut down. The relief valve comprises a ball which is normally held in a closed position by an arcuate leaf spring wrapped partially around the nozzle port.
