摘要： A fluid injection valve has a valve needle and an electromagnetic actuator assembly with a pole piece and an armature. The valve needle includes a retainer element for limiting an axial displacement of the armature with respect to the valve needle in a first axial direction. The pole piece has a central opening with a step so that it has a first section in which a first portion of the retainer element is arranged and a second section for receiving a second portion of the retainer element. The first section of the central opening has a smaller cross-sectional area than the second section.

摘要： A fluid injector includes a valve body, a valve needle and axially moveable in the valve body between a closing position that prevents a fluid injection and further positions that permit the fluid injection, an armature coupled to the valve needle for displacing the valve needle away from the closing position, and a solenoid assembly including at least a first and second coil and operable to magnetically actuate the armature via an electrical signal. A method for operating the fluid injector includes applying the electrical signal to the first coil to generate a magnetic field to move the armature for displacing the valve needle away from the closing position, evaluating a voltage across terminals of the first coil, and controlling the second coil with a further electrical signal to saturate a magnetic field in a portion of the valve body between the armature and solenoid assembly during evaluating the voltage.

摘要： The present disclosure relates to a fuel injector for injecting fuel into a combustion engine. It may comprise a valve with a movable needle, two springs pushing the needle toward the closed position, and an actuator for opening the valve. The needle may be in a fuel reservoir of a valve body. The actuator may supply pressurized fuel to the fuel reservoir so that the fuel pressure forces the needle away from the closed position against the spring force of the first spring or the first and second springs, respectively. There may be play between the second spring and the needle when the needle is in the closed position.

摘要： 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.

摘要： A valve body for an electromechanically operable valve is produced by providing a base element with a circumferential sidewall having a first portion, a second portion, and a third portion, the sidewall being made of a ferromagnetic material and enclosing a cavity extending along a longitudinal axis. The third portion is positioned in longitudinal direction between the first portion and the second portion. A thickness of the third portion is smaller than a thickness of the first portion and the second portion. Hardening the third portion is achieved by laser heating, which transforms a material structure of the third portion into a martensitic structure. The locally decreased thickness creates a bottleneck for a magnetic flux, and a magnetic flux bypass in the valve body is reduced due to magnetic saturation; however, a structural resistance of the valve body remains high due to the laser induced hardening.
