ABSTRACT:
A shutter in the form of a needle is controlled by a rod in turn controlled y an electromagnetic metering valve and which acts on the needle via a cylindrical plate formed in classes differing in terms of height. The plate for fitment between the rod and the needle is selected from the class corresponding to the travel of the needle required to open one or more orifices in the nozzle; and, to absorb any transverse components of the forces exchanged between the rod and needle and so prevent wear of the contacting surfaces of the needle and nozzle, the plate is guided inside the injector body with a very small clearance, e.g. in the region of 0.02 mm.
