PURPOSE:To exactly iliminate the emission of odors at the time of fire extinguishing as well as shorten the time of oil sending until ignition by providing an expandible film to a part of the wall of an oil supply tube and a solenoid to expand or contract the expandible film. CONSTITUTION:At the time of fire extinguishing, the supply of electricity to a pump 1 and a solenoid 13 is interrupted. Since a plunger 14 is pulled by a spring 15 when electrification to the solenoid 13 is interrupted, the expandible film 11 of a spuit 12 becomes elongated. In this case, since fuel filled up to the outlet of the oil supply tube 2 is sucked by the expandible film 11 of the spuit 12, fuel is lost from the outlet of the tip of the oil supply tube 2, and therefore, the return of fuel in the oil supply tube to a vaporizing chamber 8 is avoided. The emission of odors at the time of fire extinguishing can thus be eliminated. At the time of ignition, fuel sucked by the spuit 12 is instantaneously returned into the oil supply tube by the action of the solenoid 13. The time when fuel reaches the burner can thus be shortened.
