ABSTRACT:
A fuel injector for an internal combustion engine has an inlet member provided with an enlarged transverse opening which receives a tubular nozzle body having a peripheral shoulder to locate the inlet member longitudinally on the nozzle body. A shallow annular groove is formed around the periphery of the nozzle body in alignment with the fuel feed passage of the inlet member to provide a restricted annulus for delivering fuel to the interior of the nozzle body. The tubular nozzle body includes a plurality of inlet ports which communicate with the restricted annulus and are angularly spaced from the fuel feed passage so that the restricted annulus serves as a filter to remove solid particles entrained in the fuel. The inlet member is shrunk or press fit on the nozzle body without welding and a cap member provides a spring chamber to mount a spring which biases the valve against its seat and the inlet member against the shoulder. A non-threaded bushing is pressed into the end of the cap member to adjust spring pressure and a non-threaded lift stop is pressed into the bushing to adjust the lift of the nozzle valve. In an alternative, the valve guide is a removable bushing sealed to the nozzle body and retained therein by the bias of the cap member.
