摘要： In a gas-supply system for internal-combustion engines, a pressure-reducing valve is arranged between the reservoir of the gas and a distribution manifold or rail that feeds the gas to a series of electromagnetically controlled injectors associated to the various cylinders of the engine. The pressure-reducing valve has an internal chamber for collection of any leakage of gas which is connected to the intake manifold of the internal-combustion engine so as to enable the leaked gas to be discharged in the engine. A solenoid shutoff valve is arranged in the connection to the intake manifold and is opened automatically upon ignition of the engine.

摘要： In a gas-supply system for internal-combustion engines, a pressure-reducing valve is set between the reservoir of the gas and a distribution manifold or rail that feeds the gas to a series of electromagnetically controlled injectors associated to the various cylinders of the engine. The reduced pressure supplied by the pressure-reducing valve is further reduced via a pressure-regulating solenoid valve, to an extent that depends upon the supply current of its solenoid. The electrical supply to the solenoid of said solenoid valve is controlled by an electronic control unit according to the signal issued by a sensor of the pressure in the rail and according to stored maps, which supply the optimal pressure value for each operating condition of the engine.
