Abstract
A nozzle assembly includes a first needle and a second needle controlling respectively fuel flow towards a first series of outlets and a second series of outlets. It includes a passive control valve adapted to select, on the basis of the fuel feeding pressure, the needle to be activated for fuel delivery to the combustion chamber of an internal combustion engine. An injector with such an assembly is economic and efficient to spray fuel with two different patterns.
