  • MEANS FOR ALIGNING AND PRE-STRESSING COMPONENTS OF A FUEL INJECTOR ASSEMBLY
    Publication number: 20100258656
    Abstract: A fuel injector for an internal combustion engine, the fuel injector being of a type with an open-ended nozzle body adjoining an injector body. The interface between the nozzle body and the injector body is flat, to simplify manufacture, and they are aligned relative to each other using a compression element which is typically a sleeve that extends around them. The compression element also acts to apply a pre-compression to at least one of the bodies to enable the fuel injector to operate at higher fuel pressures than would otherwise be possible.
