Abstract (en)

A valve assembly (2) for a fluid injection valve (3) is disclosed. The valve assembly (2) has a longitudinal axis (L) and comprises a valve body (4) having a valve cavity (45) and a valve seat (40), a valve needle (1) and an armature (7), the valve needle (1) and the armature (7) being arranged in the valve cavity (45) in axially moveable fashion. The valve seat (40) has a first set of orifices (41) and a second set of orifices (42). The valve needle (1) comprises a tip portion (10), the tip portion (10) having a first section (11) and a second section (12). The first section (11) is operable to seal the first set of orifices (41). The second section (12) is operable to seal the second set of orifices (42) and is axially movable with respect to the first section (11). The armature (7) is operable to interact mechanically with the valve needle (1) for axially displacing the first section (11) away from the valve seat (40). Further, a fluid injection valve (3) and a method for operating the fluid injection valve (3) are disclosed.
