  "textContent": "A fluid injection valve (10) comprises a fluid inlet tube (12) with a recess (44) and a valve body (20) including a central longitudinal axis (L). The valve body (20) comprises a cavity (24) with a fluid outlet portion (28). Furthermore, the injection valve (10) comprises a valve needle (22) received in the recess (44) and in the cavity (24). The valve needle (22) is axially displaceable with respect to the fluid inlet tube (12) and the valve body (20) for preventing a fluid flow through the fluid outlet portion (28) in a closing position and releasing the fluid flow through the fluid outlet portion (28) in other positions. The injection valve (10) comprises a spring element (30) arranged in the recess (44) and operable to interact with the valve needle (22) for biasing the valve needle (22) in axial direction towards its closing position, wherein the spring element (30) is configured such that a spring stiffness of the spring element (30) depends on a pressure of fluid in the recess (44).",
