(57) Abstract :
A fuel injector (1) for an internal combustion engine, the fuel injector (1) being of a type with an open-ended nozzle body (3)
adjoining an injector body (21). The interface (57) between the nozzle body (21) and the injector body (21) is flat, to simplify
manufacture, and they are aligned relative to each other using a compression element (10) which is typically a sleeve that extends
around them. The compression element (10) also acts to apply a pre-compression to at least one of the bodies (3,21) to enable the fuel
injector to operate at higher fuel pressures than would otherwise be possible. [With reference to Figure 6]
