Abstract (en)
Injection valve comprising a central longitudinal axis (L) and a valve needle (10). The valve needle (10) comprises a valve needle body (20) being actuated to move axially. The valve needle (10) further comprises a sealing element (50) preventing a fluid injection in a closing position and permitting the fluid injection in further positions. Furthermore the valve needle (10) comprises at least one damping element (60) being arranged to couple the valve needle body (20) to the sealing element (50). The damping element (60) is operable to absorb at least partially a kinetic energy of the valve needle body (20), if the sealing element (50) reaches its closing position.
