摘要： PROBLEM TO BE SOLVED: To provide an injector capable of restraining the occurrence of a rich spike phenomenon to stabilize the combustion state. SOLUTION: An injection port 22 for injecting liquefied-petrileum gas is formed in a plate part 20 provided integrally with a valve 18 held in a housing 11 to reciprocate. The plate part 20 is guided in the state of close contact with a cylindrical part 15 communicated with the fuel passage outside the housing 11. With vibration of the valve 18, a gap permitting liquefied-petrileum gas to pass therethrough is formed between a projection 24 of a valve receiving part 16 and the injection port 22, thereby injecting the gas. Ice generated in gasifying the gas and adhering to the injection port 22 and the inner peripheral side of the cylindrical part 15 is shaken off or scraped off to be removed by the vibration of the plate part 20 caused by the vibration of the valve 18.

摘要： PROBLEM TO BE SOLVED: To prevent vaporization of fuel inside an injector and icing occurring by heart removal by injected fuel. SOLUTION: This fuel supply device holds the injector 11 in a mounting hole 61 formed on a cylinder head 6 and injects/supplies fuel from an injection port 201 opened on a tip face of the injector 11. A fuel guide passage 401 for guiding the fuel from the injection port 201 is provided and a thermal conductivity member 4 surrounding the fuel guide passage 401 and abutting on the cylinder head 6 is arranged thereon. Thereby the vicinity of an outlet 4011 of the fuel guide passage 401 is not overcooled by the fuel and receives heat from the cylinder head 6 by holding the injector 11 in the mounting hole 61 via a heat insulating holding member 3 for preventing the fuel inside the injector 11 from vaporizing.

摘要： A fuel injector including a valve housing having a nozzle for columnarly injecting fuel and a valve seat continuing from the nozzle; a valve body reciprocatably mounted in the valve housing and having a valve portion adapted to abut against and retract from the valve seat and thereby close and open the nozzle, respectively; and an adapter fixed to a front end of the valve housing. The adapter is formed with an atomizer hole communicating with the nozzle and an assist air passage extending through a side wall of the adapter for supplying an assist air into the atomizer hole to atomize the columnar fuel injected from the nozzle. Both the valve portion and the valve seat are formed to have surfaces in a conical shape so that upon retraction of the valve portion, the space generated between the surfaces becomes uniform over substantially the length of the surfaces.
