1. An actuator arrangement for an electromagnetically actuatable valve, comprising:
a housing comprising a first housing wall and a second housing wall situated opposite the first housing wall,
a solenoid armature arranged in the housing between the first housing wall and the second housing wall and movable between the first housing wall and the second housing wall along an axis, wherein the solenoid armature has a first axial armature end surface, which faces toward the first housing wall, and a second axial armature end surface, which faces toward the second housing wall, and the solenoid armature is movable between a first position, in which the first axial armature end surface makes contact with the first housing wall, and a second position, in which the first axial armature end surface has been moved away from the first housing wall,
at least one damping element which is arranged on the second axial armature end surface and which extends from the second axial armature end surface in a direction of the second housing wall and which comprises an elastomer material with progressive spring characteristic, wherein the at least one damping element makes contact with the second housing wall both in the first position and in the second position of the solenoid armature, and
at least one stop element which is arranged on the second axial armature end surface and which extends from the second axial armature end surface in the direction of the second housing wall and which comprises an elastomer material and which, in the first position of the solenoid armature, has been moved away from the second housing wall and, in the second position of the solenoid armature, makes contact with the second housing wall,
wherein the at least one damping element has a first extent dimension in an axial direction of the solenoid armature, has a second extent dimension in a circumferential direction of the solenoid armature, and has a third extent dimension in a radial direction of the solenoid armature, and a ratio of the first extent dimension to the second extent dimension lies in a range between approximately 1 and approximately 2, and a ratio of the first extent dimension to the third extent dimension lies in a range between approximately 1 and approximately 2.
