1. A fuel injector assembly comprising:
an inlet with a first end defining an opening for receiving fuel from a common rail and a second end having a cylindrical outside surface, said opening extending through the second end of the inlet;
a valve body with an open first end having a cylindrical side wall including an inside surface receiving the second end of the inlet and an outside surface, the inlet second end axially overlapping with the cylindrical side wall of the valve body to form a joint, said valve body including a nozzle end opposite said first end;
a burst ring having a cylindrical body with an inside surface surrounding said joint between the inlet and the valve body, a first end of the cylindrical body seated against a radially projecting shoulder rigidly connected to the valve body and a second end of the burst ring defining a load-receiving surface facing the inlet first end, the joint between the inlet and valve body positioned axially between the first and second ends of the cylindrical body of the burst ring,
wherein the burst ring inside surface is in contact with said valve body outside surface at an axial position surrounding the joint between the inlet and valve body, said burst ring providing support to the joint against outward forces generated by pressurized fuel within the connected inlet and valve body.
