Abstract

Wtryskiwacz zawiera korpus (1), w którym osadzone są: cewka elektromagnesu (4), stopa zaworu (6), nurnik (7) z igłą zamykającą (8), sprężyna (9) rozpierająca stopę (6) i nurnik (7), dysza wylotowa (10) oraz końcówka przyłącza a sprężone paliwo gazowe jest doprowadzane do wtryskiwacza poprzez otwory boczne w korpusie (1) lub wzdłużny otwór w stopie zaworu i nurniku (7), charakteryzuje się tym, że końcówka przyłącza zawiera, od strony czołowej, gwint zewnętrzny (G) przystosowany do wkręcenia w nagwintowany otwór wylotowy środkowej części (2) korpusu (1), walcową powierzchnię z rowkiem na pierścień uszczelniający (14) oraz płaską czołową powierzchnię, natomiast, od strony tylnej, zawiera przewód odprowadzający (15). Między dolną powierzchnią dyszy wylotowej (10) i płaską czołową powierzchnią końcówki przyłącza osadzony jest kalibrator (13) przepływu w postaci podkładki z otworem.The injector contains a body (1) in which the solenoid coil (4), valve foot (6), plunger (7) with closing needle (8), spring (9) spreading the foot (6) and plunger (7) are mounted, the outlet nozzle (10) and the end of the connection and the compressed gas fuel is fed to the injector through the side holes in the body (1) or the longitudinal hole in the valve foot and the plunger (7), characterized by the fact that the connection end has a thread from the front side the outer (G) adapted to be screwed into the threaded outlet hole of the central part (2) of the body (1), the cylindrical surface with a groove for the sealing ring (14) and the flat face, while, on the back side, it has a discharge pipe (15). A flow calibrator (13) in the form of a washer with an opening is mounted between the bottom surface of the outlet nozzle (10) and the flat front surface of the connection tip.
