An injector (6) of gaseous fuel comprises a body (2) provided with a chamber (3) able to receive the pressurised fuel, a conduit (4) for evacuating the fuel from the injector, having an inlet positioned internally to said chamber (3), a shutter element (5) operatively connected to the body (2), movable between a closed position, in which it is active on the inlet of the conduit to occlude a passage of fuel from the chamber to the conduit, and an open position, in which it is not active on the inlet of the conduit, to allow a passage of fuel from the chamber to the conduit, and an interchangeable nozzle (6), removably associated with the body and internally defining said conduit (4), said nozzle being operatively in contact with the shutter element, when said element is in the closed position. In prior art solutions, a choke is applied in the conduit externally to the body, in intermediate position between the inlet and the outlet of the conduit, not allowing to manage small displacement engines in an efficient manner. |
