ABSTRACT:
A valve assembly (60) for an injection valve (62) has a valve body (4) including a central longitudinal axis (L), the valve body (4) has a cavity (8) with a fluid inlet portion (42) and a fluid outlet portion (44), a valve needle (10) axially movable in the cavity (6), the valve needle (10) preventing a fluid flow through the fluid outlet portion (44) in a closing position and releasing the fluid flow through the fluid outlet portion (44) in further positions, and a fluid flow directing element (46) arranged in the fluid outlet portion (44) coaxially between the valve body (4) and the valve needle (10) and extending in radial direction away from the valve needle (10) in a way that a fluid flow between the valve needle (10) and the fluid flow directing element (46) is prevented.
