Valve for metering a fluid

A valve for metering a fluid, comprising:

• a housing;
• an electromagnetic actuator;
• a valve needle actuatable by the actuator, wherein an armature of the actuator is guided on the valve needle;
• a stop element that limits a movement of the armature relative to the valve needle, wherein the stop element is situated on the valve needle;
• a spring supported on the stop element, wherein the armature includes a spring receptacle that is open toward the stop element and in which the spring supported on the stop element is inserted, wherein the valve needle is guided via at least one of the armature and the stop element along a longitudinal axis of the housing, and wherein as viewed along the longitudinal axis, a length of the spring receptacle is smaller than a spring length of the spring in a non-actuated initial state;
• and
• wherein, as viewed along the longitudinal axis, at least one of:
• a guide length over which the armature is guided on the valve needle is not smaller than an armature length, and the guide length over which the armature is guided on the valve needle is made up of a length of the armature that is shortened by the length of the spring receptacle, plus at least one of a length of a guide web and a length of a guide extension.

• wherein the armature includes at least one through-opening that extends along the longitudinal axis and is combined with the spring receptacle, and
• wherein the at least one through-opening has an expanded kidney-shape in a circumferential direction.

• and
• a guide extension that guides the armature along the longitudinal axis on the valve needle, wherein the guide extension is provided on the armature;
• wherein the spring receptacle directly abuts the valve needle, and wherein the spring receptacle is implemented by a cylindrical recess oriented on the longitudinal axis.
