Abstract
The injector has a hollow body carrying a nozzle, and a metering valve hag a valve body housed in a cylindrical seat of the hollow body. The valve body has a distribution cavity for distributing high-pressure fuel to a control chamber of the valve, whereas the seat communicates with a cavity at atmospheric pressure and in which the control rod slides. The sealing device has an annular seal, which is compressed between two shoulders carried by the surface of the seat and by an outer surface of a portion of the valve body so as to provide for redundant sealing between the two surfaces.
