A control pressure chamber is located adjacent the major area diaphragm on a side thereof opposite to the reference pressure chamber and a controlled pressure chamber is located adjacent the minor area diaphragm on a side thereof opposite to the reference pressure chamber. A valve is connected to the diaphragms for regulating the opening of an orifice of a fuel passage and the controlled pressure chamber serves as a chamber of the fuel passage. The control pressure chamber is connected to a combustion air supply passage system, and the reference pressure chamber is connected to a portion of an air supply and exhaust passage system, in which the pressure is lower than the pressure in the combustion air supply passage system.
