    Abstract: A gas injector for injecting a gaseous fuel. The gas injector includes a solenoid actuator including an armature, an internal pole, and a coil; a closure element which opens and closes a gas path on a valve seat, the armature being connected to the closure element; a closed lubricant chamber filled with a lubricant and in which the armature is arranged, the lubricant ensuring the armature is lubricated; a flexible sealing element sealing the lubricant chamber in relation to the gas path, and a braking device which is arranged in the lubricant chamber and is configured to brake the closure element during a process of restoring the gas injector from the open into the closed state. The braking device has a brake pin, a damping chamber that is filled with lubricant and is in fluid communication with the lubricant chamber, and a resilient brake element.

    Abstract: A valve assembly for a fluid injection valve may comprise a valve body, a valve needle moving in a cavity of the valve body, an armature in the cavity for actuating the valve needle, and a particle retainer. The cavity may extend axially through the valve body to connect a fluid inlet end to a fluid outlet end of the valve body and have a valve seat adjacent to the fluid outlet end. The first portion of the cavity may limit movement of the armature in the axial direction towards the fluid outlet end by a bottom surface having a central opening from which a second portion of the cavity extends towards the fluid outlet end. The shaft of the valve needle may extend through the opening into the second portion. The particle retainer element may bear on the bottom surface, circumferentially surrounding the shaft of the valve needle and overlapping the opening.

    Abstract translation: 用于流体喷射阀的阀组件可以包括阀体，在阀体的空腔中移动的阀针，用于致动阀针的空腔中的电枢和颗粒保持器。 空腔可以轴向延伸穿过阀体以将流体入口端连接到阀体的流体出口端并具有邻近流体出口端的阀座。 空腔的第一部分可以限制电枢在轴向方向上朝向流体出口端的移动，具有中心开口的底表面，空腔的第二部分从该中心开口延伸朝向流体出口端。 阀针的轴可以穿过开口延伸到第二部分。 颗粒保持元件可以承载在底表面上，周向地围绕阀针的轴并与开口重叠。

    Abstract: The disclosure relates to a fuel injector arranged in a recess of a cylinder head of a combustion engine. It may comprise a housing, a valve body, and an adjustment element. The valve body may have a central area, an end area, and a transition area, with a first outer diameter (D1) in the central area the valve body, and a second outer diameter (D2) in the end area which is smaller than the first outer diameter (D1). The adjustment element may be shaped and positioned in the transition area of the valve body to align the fuel injector relative to the recess. In the transition area, an outer diameter of the valve body decreases in stepped fashion from the first outer diameter (D1) to the second outer diameter (D2) so that a radially extending step surface is formed. The adjustment element comprises a ring element through which the transition area extends and the adjustment element has a radially extending upper surface which radially overlaps, contacts, and is coplanar to the step surface and a spherically shaped external surface in a cylinder head contact area.
