Abstract

See full text

In a gaseous-fuel-injector device for internal-combustion motor-vehicle engines, the valve body of the injector device has one or more auxiliary openings giving out onto an internal surface of the valve body in which the valve member of the injector device is slidably mounted. Said auxiliary openings are arranged in such a way as to enable the inflow of the gaseous fuel coming from the supply, not only into the inlet opening of the injector device, but also into the internal area of the valve body in which the valve member 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.
