Title (EN) FUEL INJECTION VALVE WITH AN ANTI BOUNCE DEVICE, COMBUSTION ENGINE AND VEHICLE
(FR) SOUPAPE D'INJECTION DE CARBURANT COMPRENANT UN DISPOSITIF ANTIREBOND, MOTEUR À COMBUSTION INTERNE ET VÉHICULE
Abstract:
(EN) A fuel injection valve (1) is disclosed. It comprises a valve body (12) with a cavity (18), a valve needle (14) movable in the cavity (18), an actuator assembly (5) to actuate the valve needle (14), and an armature element (33) being movable in the cavity (18) to push a retainer portion (31) of the valve needle (5). The fuel injection valve (1) further has an anti-bounce device (46) which is operable to effect a spring force and a hydraulic force for dampening a movement of the armature element (33). The anti-bounce device (46) comprises a spring portion (50) for effecting the spring force and a hydraulic damper portion (53) for effecting the hydraulic force, wherein the hydraulic damper portion (53) is integrally connected to the spring portion (50).
(FR) L'invention concerne une soupape d'injection de carburant (1). Elle comprend un corps de soupape (12) avec une cavité (18), un pointeau de soupape (14) déplaçable dans la cavité (18), un ensemble d'actionneur (5) pour actionner le pointeau de soupape (14), et un élément d'armature (33) pouvant être déplacé dans la cavité (18) pour pousser une portion de retenue (31) du pointeau de soupape (15). La soupape d'injection de carburant (1) présente en outre un dispositif antirebond (46) qui est apte à appliquer une force de ressort et une force hydraulique pour amortir un mouvement de l'élément d'armature (33). Le dispositif antirebond (46) comprend une partie de ressort (50) pour appliquer la force de ressort et une partie d'amortisseur hydraulique (53) pour appliquer la force hydraulique, la partie d'amortisseur hydraulique (53) étant connectée intégralement à la partie de ressort (50).
