Patent

CA 2605766

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.

L~invention concerne un injecteur de carburant à rail commun (1) possédant un corps forgé contenant une buse et un réservoir (2) pour alimenter la buse en carburant. Pour en réduire la hauteur, le corps intègre en monobloc un limiteur de débit (4) et un filtre (5) dans une partie saillant latéralement (1a) à laquelle est raccordé (18) le tuyau de carburant. Ceci signifie que le réservoir peut être maintenu en place sous le cache-culbuteurs du moteur (30) par une pince (3) entre les culbuteurs (16) de manière économe en place et l~injecteur peut être déposé sans dérégler les soupapes.
