Beschreibung
Zusammenfassung:	The feed device (12) has, for each cylinder of the engine, a solenoid valve (15) for feeding fuel gas to a corresponding cylinder of the engine. The solenoid valve (15) has at least one shutter (32) carried by an armature of a corresponding electromagnet (22,22'), which armature is defined by an oblong plate (33) rotating about a line a contact defined by an edge (42) of the plate (33) contacting a flat surface (30) of a fixed member (26). The plate (33) is pushed into position closing the solenoid valve (15) solely by an elastic bar (47). The edge (42) is located between a flat surface (44) of the plate (33) and an inclined portion (43) forming with the flat surface (44) an angle ( alpha ) of less than 20 DEG . The outlet conduits (31,48;31,48') have corresponding nozzles (48,48') of possible different diameters.
