Title (EN) FUEL INJECTOR VALVE
(FR) SOUPAPE D'INJECTION DE CARBURANT
Abstract: front page image
(EN)A fuel injector valve (1) of a piston engine, which comprises a fuel chamber (3) for the fuel to be injected, a valve needle (9) for guiding the fuel injection from the fuel chamber (3) into the cylinder (4) of the engine, a spring (10) for pressing the valve needle (9) towards the closed position, and a piezoelectric actuator (11) for guiding the valve needle (9). Additionally, the injector valve (1) comprises a drawbar (22), which is loosely coupled to the valve needle (9), a second drawbar (23), which is attached to the piezoelectric actuator (11) and loosely coupled to the drawbar (22), and that the injector valve (1) comprises a second spring (24) fitted in connection with the drawbar (22) for pressing the valve needle (9) towards the closed position and a third spring (25) fitted in connection with the second drawbar (23) for pressing the valve needle (9) towards the closed position.
(FR)L'invention concerne une soupape d'injection de carburant (1) d'un moteur à piston, comprenant une chambre de carburant (3) pour le carburant devant être injecté, un pointeau de soupape (9) pour guider l'injection du carburant depuis la chambre de carburant (3) dans le cylindre (4) du moteur, un ressort (10) pour presser le pointeau de soupape (9) vers la position fermée, et un actionneur piézoélectrique (11) pour guider le pointeau de soupape (9). En outre, la soupape d'injection (1) comprend une barre de traction (22), couplée de façon lâche au pointeau de soupape (9), une seconde barre de traction (23), qui est fixée à l'actionneur piézoélectrique (11) et couplée de façon lâche à la barre de traction (22), et la soupape d'injection (1) comprend un deuxième ressort (24) installé en connexion avec la barre de traction (22) pour presser le pointeau de soupape (9) vers la position fermée et un troisième ressort (25)installé en connexion avec la seconde barre de traction (23) pour presser le pointeau de soupape (9) vers la position fermée.
