Abstract (en)

Injection valve (100), 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. The valve needle (10) also comprises a guiding element (90), being axially moveable and being fixedly coupled to the sealing element (50) and being operable to couple the sealing element (50) to the valve needle body (20). Furthermore the valve needle (10) comprises at least one spring element (60), being preloaded and being adopted to supply the sealing element (50) and/or the guiding element (90) with a spring load to absorb at least partially a kinetic energy of the valve needle body (20), if the sealing element (50) reaches its closing position.
