Abstract (en)
A multi-nozzle injector with orientated jets, in particular for an internal combustion engine of the type having one or more inlet valves for each cylinder, supplied by one or more ducts in which the valve means for the injection and metering of the fuel comprise an axially movable shutter member (18), a valve seat (19) cooperating in a fluid-tight manner with the shutter member (18) and at least one pair of nozzles (20) hydraulically connected with the valve seat through a common calibrated duct (21) adapted to meter the flow of fuel passing from the said valve seat (19) towards the said nozzles (20), in which the valve seat (19) and the calibrated duct (21) are formed in an insert element (30) defining an end wall of a hollow body (12) of the said injector housing the shutter, and in which the nozzles (20) are formed in an insert (32) fixedly inserted into the interior of a recess in the insert element (30).
