<p>The injector has primary and secondary valves (7, 10) arranged in series and moved towards closing positions. The valves (7, 10) are placed on primary and secondary fuel paths, respectively. The paths are diverged in downstream of the valve (7). The valve (10) slides in an internal body (8) delimiting the primary path. The secondary path has a hole (14) crossing the valve (10) between a periphery and a central hollow (13). An orifice (21) crosses the body between the primary path and the valve (10) and is opened in hole when the valve (10) is in closed position.</p> |
