Abstract
A solenoid actuated fuel injector includes a valve body having a longitudinal axis. A valve seat subassembly is mounted in one end of the valve body. The valve seat subassembly includes a valve seat having a seating surface and a circumferential sealing surface surrounding the seating surface. The valve seat subassembly also includes a lower needle guide and swirl disk laser welded to the valve seat. The subassembly includes a radially extending flange that axially positions the subassembly in the nose of the injector and eliminates the tolerances associated with the stack up height of conventional valve seat subassembly components.
