Abstract:
The present disclosure relates to internal combustion engines. Various embodiments may include a fuel injection system for delivering fuel to an internal combustion engine. For example, fuel injector may include a valve body having a cavity; a valve needle with a retainer moving in the cavity; an actuator assembly comprising: a spring element next to the valve needle; an electro-magnetic coil; an armature element movable in the cavity; and an anti-bounce device. The armature element may be between the retainer portion of the valve needle and the anti-bounce device. The anti-bounce device may impose a spring force and a hydraulic force for dampening a movement of the armature element. The anti-bounce device may comprise a spring portion exerting the spring force to close the valve needle and a hydraulic damper portion integrally connected to the spring portion.

Claim (Index 14):
A fuel injection valve for a combustion engine, the fuel injection valve comprising:\n a valve body having a cavity with a fluid inlet portion and with a fluid outlet portion; a valve needle movable in the cavity, the valve needle comprising a retainer portion; an actuator assembly to actuate the valve needle, the actuator assembly comprising:\n a spring element next to the valve needle; \n an electro-magnetic coil for generating a magnetic field; \n an armature element movable in the cavity, wherein the magnetic field interacts with the armature element for moving the armature element to push the retainer portion of the valve needle; and \n an anti-bounce device; \n the armature element disposed between the retainer portion of the valve needle and the anti-bounce device; the anti-bounce device operable to impose a spring force and a hydraulic force for dampening a movement of the armature element; wherein, in the closed position of the valve needle, the spring element pushes the valve needle to a first predetermined location to prevent a fluid from flowing through the fluid outlet portion; and in the open position of the valve needle, the armature element pushes the valve needle to a second predetermined location to allow the fluid to flow through the fluid outlet portion; and wherein the anti-bounce device comprises a spring portion exerting the spring force and a hydraulic damper portion integrally connected to the spring portion.
