A valve in an oil supply line 1 from a pump to a burner comprises a conical part co-operating with a conical surface 4 to close the valve, and a piston 5 which slides in the line 1. Oil pressure opens the valve and when the pump stops the valve moves under its own weight and the piston 5 closes the line before the conical part seats on the conical surface 4; oil is thus sucked back from the burner nozzle.
