    摘要: A method and fuel injector for precision setting of valve lift, using a valve body shell (42) telescoped over the valve body (60), the shell (42) having a nonmagnetic extension welded to the valve body shell (42) and to the end of an inlet tube (16) providing a solenoid pole piece, with the valve body (60) and shell (42) adjusted to set the valve lift and thereafter welded together. Interference fit portions stabilize the adjusted position of the members preparatory to welding, and displaced material in a locking groove (102) creates a mechanical interlock between the valve body (60) and shell (42) to stabilize the members in their adjusted positions after welding so that the set lift is minimally affected by weld shrinkage. An external radial groove 18 allows radial bending as the weld cools to minimize axial shift of the parts and thus the effect on the set valve lift.

    摘要: An example fuel injector orifice plate assembly includes a plastic plate within which is an orifice for metering and directing fuel flow in a desired spray pattern, and a metal support plate for supporting and maintaining the stability of the desired spray pattern generated by the orifices within the plastic plate. The orifice plate includes orifices sized to provide a desired spray pattern of fuel. The metal support plate is more rigid than the orifice plate and provides the desired strength and rigidity for withstanding the cyclical pressure fluctuations caused by operation of the fuel injector.
