Compressed natural gas injector having gaseous dampening for armature needle assembly during closing

摘要: An electromagnetically operable fuel injector for a gaseous injection system of an internal combustion engine, the having generally longitudinal axis, which includes ferromagnetic core, magnetic coil at least partially surrounding core and armature magnetically coupled to being movably responsive coil. The actuates valve closing element in form needle interacts with fixed seat is movable away from when excited. defines aperture predetermined dimension passage therethrough, elongated shape central opening axial reception inlet connector positioned adjacent thereto. are adapted permit first flow path between as part leading said valve. orifice device downstream valve, lesser than seat. A method directing through openable manner provides dampening upon also disclosed.
