| 主权项 | 1. A fuel injector, comprising: a housing having at least one spray orifice; an armature assembly that is linearly movable in the housing along a longitudinal axis, wherein the armature assembly has at least one fuel opening; a magnetic coil acting magnetically on the armature assembly; a valve element that is linearly-movable with respect to the armature assembly and with respect to the housing, for opening and closing the spray orifice; a pin for limiting the movement of valve element with respect to the armature assembly, wherein the pin crosses the valve element from a first side of the armature assembly to a second side of the armature assembly; and a damping chamber, in the armature assembly, that is able to be filled with fuel, for damping a movement of the armature assembly with respect to the valve element. | ||
