FOAMING INJECTION MACHINE FOR PNEUMATIC MECHANICAL TYPE SYSTEM FOR INJECTING AIR/FUEL MIXTURE INTO TURBO-MACHINE COMBUSTION CHAMBER

摘要

PROBLEM TO BE SOLVED: To provide an injection machine for a pneumatic mechanical type injection system for reducing characteristic time for spraying and vaporizing fuel over the whole operation speed of a turbo-machine. SOLUTION: This fuel injection machine 2 for the pneumatic mechanical type injection system for injecting air/fuel mixture into a turbo-machine combustion chamber is provided with a tubular main structural body 4 opened in an end part 4a on the downstream side to supply air/fuel mixture and having an axis XX', a tubular fuel duct 6 arranged on an inner side of the main structural body 4 and opened into the main structural body 4 through a fuel sprayer plug 10 to introduce fuel into the main structural body at pressure Pc, at least one air supply flow passage 12 opened in the main structural body 4 to introduce air into the main structural body at pressure PA, and a means for injecting gas into the fuel duct 6 at pressure PGbeing higher than PAand higher than PCor equal to PCto cause foaming of fuel when introducing fuel into the main structural body 4.
