Abstract (en)

A fuel supply device comprising a pressurized air passage, a nozzle opening (24) formed at a tip end of the pressurized air passage to inject fuel and pressurized air, a valve for opening or closing the nozzle opening (24), a fuel injector (36) for injecting fuel in the pressurized air passage (38), and a guide member (39) arranged in the pressurized air passage between the nozzle opening (24) and the fuel injector (36). The guide member (39) has at least three contacting faces (39a) which are in contact with a cylindrical inner wall (22) of the pressurized air passage, and at least three substantially flat faces (39b) each extending approximately in a straight line between the contacting faces (39a) which are located on each side of the flat face to form a narrow passage (40) between the cylindrical inner wall (22) of the pressurized air passage and the flat face (39b).
