Abstract: A system for feeding gas fuel to an internal combustion engine, having: a fuel tank; fluidic connector along which fuel flows, and interposed fluidically between the tank and a cylinder of the engine; and an electro-injector fluidically in series with respect to the fluidic connector, and which is interposed between the tank and the cylinder, and is activated selectively to disable or enable fuel flow to the cylinder; the electro-injector is positioned with respect to the fluidic connector solely by connecting at least an inlet or outlet of the electro-injector to at least one pipe defined by the fluidic connector.

Abstract: A solenoid valve assembly for a combustible gas supply device to an endothermic engine is disclosed. The solenoid valve assembly includes a solenoid valve with at least one combustible gas outlet and an armature controlled by an electromagnet, the armature having an armature plate and a shutter. The armature plate rotates about a contact line. The armature plate is engaged by a bar pushed against the plate by a spring so as to normally keep the shutter in closed position. The solenoid valve assembly includes a hollow body that may be connected to an intermediate plate that may be connected to a closing plate module. The closing plate module carries a variable number of outlet conduits. The intermediate plate is provided with a series of grooves adapted to accommodate a series of different gaskets, each gasket corresponding to a closing plate module.

Abstract: The solenoid valve assembly (5) presents an inlet union (8), at least one combustible gas outlet hole (28), and a plate (29) carrying a shutter (13) and operatable by an electromagnet (19) for controlling the solenoid valve (14). The plate (29) is turnable about a contact line (36) of one face (37) engaged by a bar (46) pushed against the plate (29) by a helical compression spring (44), so as to normally keep the shutter (13) in closed position. A valve body (7) is connected to an intermediate plate (12) carrying the outlet holes (28) and is closed by a removable and modular closing plate (9), which carries a variable number of outlet conduits (1). The intermediate plate (12) is provided with a series of grooves (56) adapted to accommodate a series of different gaskets (17), each corresponding to a module of the closing plate (9).
