PURPOSE:To permit the titled device to continue with a vaporizing combustion of proper quantity oil over an extended period, by ensuring the proper quantity of oil to be continuously supplied to a fuel oil diffusing element, which can be achieved by forming an oil supplying small clearance between a fuel oil diffusing surface and a oil supplying port and also an oil supplying clearance larger than the first oil supplying clearance between the fuel oil diffusing surface and the upper edge of oil supplying port. CONSTITUTION:An oil supplying pipe 19 provided to ensure a positive supply of fuel oil to a fuel oil diffusing rotary surface 17 has its top side inclined downwardly towards a fuel oil diffusing element 16, while having its end portion downwardly and slantedly cut and defined as an oil supplying port closely to the oil diffusing surface 17 of lower side. An oil supplying small clearance 23 is formed between the lower edge 21 of slantedly cut oil supplying port 20 and the fuel oil diffusing surface 17, whereas an another oil supplying clearance 24 larger than the small clearance 23 is formed between the upper edge 22 of oil supplying port 20 and the fuel oil diffusing surface 17, and thereby ensuring that the fuel oil can be exactly supplied to the fuel oil diffusing surface 17 in an extensive range from a small to a large flow rate without causing a dripping flowout or a splashing phenomenon. |
