Fluid valve and method for controlling the supply of fluid

A fluid valve, comprising:

• a valve housing extending from a fluid inlet to a fluid outlet along a longitudinal central axis and comprises at least one first valve assembly, wherein the first valve assembly comprises
• a valve needle,
• an electromagnetic actuating device, wherein the valve needle is movable in a cavity of the valve housing along the longitudinal central axis, wherein the electromagnetic actuating device has an armature, which is coupled to the valve needle, and a pole piece, which is coupled to the valve housing, wherein the armature has on an armature stop side which is opposite the pole piece an armature stop surface, and the pole piece has on a pole piece stop side which is opposite the armature a pole piece stop surface,
• a deformable first ring element, and
• a deformable second ring element between the armature stop side and the pole piece stop side, and in a view along the longitudinal central axis, an inner contour of the first ring element extends outside an outer contour of the second ring element.
