(FR) BROCHE DE POSITIONNEMENT
Abstract
(EN)
A fuel injector assembly has a control valve body and a plurality of end caps. End cap locating holes are formed into a mating surface of each end cap, and control valve body locating holes are formed into each mating surface of the control valve body. Locating pins inserted into the end cap and control valve body locating holes each have a fixed portion that affixes the locating pins to either the control valve body or the end cap. In the event of failure of a locating pin between the fixed portion and a free portion of the pins, the free portion maintains alignment of the control valve body locating holes with the end cap locating holes.
(FR)
La présente invention concerne un ensemble d'injecteur de carburant présentant un corps de soupape de commande et une pluralité de capuchons d'extrémité. Des orifices de positionnement de capuchon d'extrémité sont formés dans une surface de contact de chaque capuchon d'extrémité et des orifices de positionnement de corps de soupape de commande sont formés sur chaque surface de contact du corps de soupape de commande. Les broches de positionnement insérées dans les orifices de positionnement de corps de soupape de commande et de capuchon d'extrémité présentent tous une partie fixe qui fixe les broches de positionnement soit au corps de soupape de commande soit au capuchon d'extrémité. En cas de défaillance d'une broche de positionnement entre la partie fixe et une partie libre des broches, la partie libre conserve l'alignement des orifices de positionnement de corps de soupape de commande avec les orifices de positionnement de capuchon d'extrémité.
