Abstract (en)
Valve assembly (14) for an injection valve (10) which comprises a valve body (20) including a central longitudinal axis (L) and comprises a cavity (24) with a fluid outlet portion (28). The valve assembly comprises a valve needle (22) axially movable in the cavity (24), the valve needle (22) has a front surface (37) turned away from the fluid outlet portion (28) and a recess (38) which is arranged in direction of the central longitudinal axis (L) from the front surface (37) over a portion of the axial length of the valve needle (22). The valve needle (22) is preventing a fluid flow through the fluid outlet portion (28) in a closing position and is releasing the fluid flow through the fluid outlet portion (28) in further positions. The valve needle has a surface (23) facing the fluid outlet portion (28), one component of the normal of the surface (23) extending in parallel to the central longitudinal axis (L).
