PURPOSE:To provide a combustion equipment in which a solenoid valve to jet out fuel which is provided opposite to an ultrasonic wave oscillating element horn is connected to a fuel supply circuit for maintaining the pressure for supplying the fuel constant, and even when the liquid fuel is throttled there is no fear of forming liquid drops. CONSTITUTION:A solenoid valve 16 which is provided opposite to an oscillation element horn 3 and jets out liquid fuel opens and closes the needle valve on its tip by energizing and deenergizing its solenoid coil. The solenoid valve 16 is connected to a fuel supply circuit 17 so that it will be able to supply a liquid fuel always under a constant injection pressure. The circuit 17 is constituted of the lines which connect a fuel tank 18, fuel pump 19, and pressure regulating valve 20, and a line which supplies fuel to the solenoid valve 16 from the line between the pump 19 and regulating valve 20 is formed to branch off. By regulating the degree of opening of a regulating valve 20 part of the fuel is recycled to the fuel tank 18, and the pressure of the fuel supplied to the solenoid valve 16 is regulated so that it is always at a constant pressure. |
