ABSTRACT:
A fuel supply device comprising a plurality of air assist type fuel injectors each having a nozzle opening, an assist air passage connected to the nozzle opening, and a fuel valve for injecting fuel into the assist air passage. The assist air passages of all of the fuel injectors are connected to a common air manifold via corresponding assist air supply control valves. The air manifold is connected to a fuel pressure regulator for controlling the pressure of fuel fed into the fuel valves. This pressure of fuel is maintained at a pressure higher than the pressure of air in the air manifold, by a fixed pressure, by the fuel pressure regulator.
