Abstract
TITRE : Dispositif de protection contre les chocs pour un système d'injection d'un moteur à combustion interne Dispositif de protection (3) contre les chocs pour un système d’injection (4) d'un moteur (2) à combustion interne, le dispositif de protection (3) comportant un corps (5) et un organe d’accroche (6), relié au corps (5), configuré pour s’étendre en prise de la rampe d’injection (41) de sorte à assurer un contact permanent avec au moins une surface plane de la rampe d’injection (41) et d’en prévenir le déplacement relativement à au moins un injecteur d’un moteur (2). Figure de l’abrégé : Figure 2TITLE: Impact protection device for an injection system of an internal combustion engine Impact protection device (3) for an injection system (4) of an internal combustion engine (2), the protection device (3) comprising a body (5) and an attachment member (6), connected to the body (5), configured to extend in engagement with the injection rail (41) so as to ensure a permanent contact with at least one plane surface of the injection rail (41) and to prevent its displacement relative to at least one injector of an engine (2). Abstract Figure: Figure 2
