This invention relates to an electrical injector for gaseous fuel including: a body (1) with a cavity that constitutes the seating (3) of a shutter device (7) a gas feed duct (2) which leads from the said seating (3) to the engine an electromagnet (4) posi...

A gaseous fuel injector for an internal combustion engine or a propulsion system using fuel cells has an electromagnetic solenoid with a flat rectangular armature (13) which seats agains a seat member (15) to form a valve. The valve is kept in a closed pos...

An inlet (2) delivered gas to an upper chamber (13), in the valve body (1), that communicates also (8) with a lower chamber (7). The passage of gas from the latter into the interior projection (9) of the outlet orifice (30) is prevented, when the valve is ...
