ABSTRACT:
A unit fuel injector is provided which includes a threadless injector body attaching device for attaching an upper body section of the fuel injector to a lower body section while avoiding imparting a transverse load to the upper body section thereby minimizing bore distortion, plunger wear and the likelihood of injector failure. The threadless injector body attaching device includes a groove formed in the lower end of the upper body section and one or more apertures extending through the lower body section for positioning adjacent the groove. Also, one or more pins are provided for insertion into a respective aperture and connection to the lower body section. The groove and opposing aperture or apertures are sized to create a slip fit to avoid a contact force between the pin or pins and the upper body section. Upon assembly, the pin, aperture and groove create a relatively loose connection between the upper body section and the lower body section without transverse loads while utilizing the clamping load imparted by an injector mounting clamp to apply the necessary sealing load to the injector body to create a fluid seal between the upper and lower body sections.
