PURPOSE:To reduce deposit of bubbles on the inside of a bypass chamber by forming a hole communicating to the bypass chamber in a hollow tubular portion formed to protrude into the bypass chamber in a communicating end of a low speed fuel path. CONSTITUTION:The lower end 6 of a hollow tube 11 forming a slow path 1 is fixed under the condition of protruding into a bypass chamber 2, and the protruding portion 6 is provided with a communicating hole 7 communicating to the path 1 and the bypass chamber 2 so that slow fuel in the bypass chamber 2 is injected inti an intake pipe 9 through a bypass port 4 and slow nozzle. Since the volume of the bypass chamber 2 is reduced by the protruding portion 6 in the bypass chamber 2 of the tube 11, deposit of bubbles in the bypass chamber 2 is reduced to reduce ununiformity of mixture. |
