In a gaseous-fuel-injector device for internal-combustion motor-vehicle engines, the valve body (6) of the injector device has one or more auxiliary openings (30) giving out onto an internal surface (19) of the valve body (6) in which the valve member (17, 18) of the injector device is slidably mounted. Said auxiliary openings (30) are arranged in such a way as to enable the inflow of the gaseous fuel coming from the supply (3), not only into the inlet opening (9) of the injector device, but also into the internal area of the valve body (6) in which the valve member (17, 18) is slidably mounted, so as to obtain an effect of ventilation and flushing, by means of the flow of gaseous fuel, in an area where there tend to form deposits of the oily substances contained in the gaseous fuel. |
