Abstract
A common-rail fuel injector (1) has a forged housing containing a nozzle and a reservoir (2) for supplying the nozzle with fuel. In order to reduce its height the housing integrally incorporates a flow limiter (4) and a filter (5) in a laterally protruding portion (1a) to which the fuel pipe is connected at (18). This means that the reservoir can be held in place underneath the engine cover (30) by a clamp (3) between the rocker levers (16) in a space-saving manner, and the injector can be removed without disturbing the valves.
