  "textContent": "During the duty cycle of an injection valve (10), pressure waves are generated inside the fluid chamber (14) of the injection valve (10) that deteriorate the operation of the injection valve (10). In order to absorb theses pressure waves, a bellows (22) is mounted in the fluid chamber (14), thereby defining a volume (24) in the fluid chamber (14) that is free of the fluid to be dosed and hermetically sealed against the rest of the fluid chamber (14). Thus, a compensatory component is provided that can easily be mounted to an armature (20) of the injection valve (10) after the valve needle (18) has been mounted to the armature (20). Only minimum influence on the construction and the assembling process is required in order to realize the present invention.",
