<p>PROBLEM TO BE SOLVED: To provide a liquid fuel combustion device preventing fuel from shooting out in excess due to the inflow of air into an electromagnetic pump at the time of pumping up in the case when the liquid fuel in an oil pan is in the decreasing state or the empty state and preventing rising flame, white smoke and odor to permit satisfactory combustion to be performed. SOLUTION: A liquid fuel combustion device is provided with an oil tray 2 storing liquid fuel to hold it and an electromagnetic pump pumping up the liquid fuel in the oil pan 2 to feed it to the combustion device through an oil transfer pipe, and the electromagnetic pump comprises a pipe body forming the channel of the liquid fuel, a projected valve arranged at the upper part of it, a plunger moving vertically with a suction valve arranged at the lower part of it and a suction pipe 3 arranged at the lower part of the pipe body to be the channel pumping up the liquid fuel in the oil pan 2. The outer wall 24 of the suction pipe 3 and the inner wall 25 of the suction channel 22 are formed in the taper shape that is gradually contracted in diameter toward the tip of the suction pipe 3, and the tip portion A of the suction pipe 3 is formed into a fine diameter.</p> |
