Abstract (en)
The invention concerns a valve assembly (11) for an injection valve (10), comprising a valve body (12) including a central longitudinal axis (L), the valve body (12) comprising a cavity (18) with a fluid inlet portion (42) and a fluid outlet portion (40), a valve needle (20) axially movable in the cavity (18), the valve needle (20) preventing a fluid flow through the fluid outlet portion (40) in a closing position and releasing the fluid flow through the fluid outlet portion (40) in further positions, and an electro-magnetic actuator unit (36) being designed to actuate the valve needle (20), the electro-magnetic actuator unit (36) comprising an armature (22) axially movable in the cavity (18). The valve body (12) has a stop surface (48) facing the fluid outlet portion (40) and facing the armature (22). The stop surface (48) is designed to act as a stop for the armature (22) in its position furthest away from the fluid outlet portion (40). The stop surface (48) is a plasma nitrided surface.
