Being the fuel injector of air assist atomizer null air assist type

摘要

(57) Abstract The atomizer is the coating body (12) of the cap condition which possesses the level insertion body (54) which consists of the metal which the stamping is done. When it is attached to the nozzle of the fuel injector, the atomizer, makes the insertion body, axis direction put with the end of the coating body and the end outside the nozzle. This in the territory where it was put, as for the insertion body, lap six channels which consist of the discontinuous section of direction (80a - 80d; 92a - 92b) we have possessed, this channel, coupled with the nozzle end and the coating body edge wall, forms air assist opening in order flow to make pass the assist air in radial facing toward the fuel which was injected from the nozzle. These six channels like below are divided into group. Namely, being vertical vis-a-vis the diameter which forms the air wall (97) because axis of the fuel style which group and the air which consist of two channels (80c and 80d) which among two axes of group and the fuel style which consist of two channels which among two axes of the fuel style were directed on the one hand, are made interval angular direction (50) were directed on the other hand, are made interval angular direction is mixed is maintained at separated state, passes by two axes of the fuel style, and it was located according to the disk diameter which two minutes it does this diameter, it opposed with diameter directionThey are with two channels (92a and 92b).
