Abstract (en)
Valve assembly (14) for an injection valve (22), comprising a valve body (20) including a central longitudinal axis (A), the valve body (20) comprising a cavity (24) with a fluid inlet portion (26) and a fluid outlet portion (28), a valve needle (22) axially movable in the cavity (24), the valve needle (22) 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 further positions, the valve needle (22) having a guide portion (46) being designed to guide the valve needle (22) in the valve body. A ring element (50) is arranged coaxially between the valve body (20) and the valve needle (22) at an axial end (48) of the needle guide portion (46) facing away from the fluid outlet portion (28). The ring element is fixedly coupled to the valve needle (22). The ring element (50) is designed to cause a given pressure drop for a fluid flow through the fluid outlet portion (28).
