摘要： The invention relates to a valve assembly for an injection valve, comprising a valve body (14) including a central longitudinal axis (L), the valve body (14) having a cavity (18) with a fluid inlet portion (42) and a fluid outlet portion (40), and a chamber (26), with an electro-magnetic actuator unit (36) being arranged in the chamber (26), and 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. The valve needle (20) is designed to be actuated by the electro-magnetic actuator unit (36). A bellows (46) is arranged between the valve body (14) and the valve needle (20) and is sealingly coupled to the valve body (14) and to the valve needle (20). The bellows (46) is designed to prevent a fluid flow between the cavity (18) and the chamber (26). Furthermore, the invention relates to an injection valve (10) comprising the valve assembly (12).

摘要： Valve assembly for an injection valve, injection valve and method for assembling a valve assembly of an injection valve. The invention relates to a valve assembly (11) for an injection valve (10) and a method for assembling a valve assembly (11). The valve assembly (11) comprises a valve body (12) with a central longitudinal axis (L). The valve body (12) comprises a cavity (18) with a fluid inlet portion (21) and a fluid outlet portion (19), an end portion (13) being arranged at an axial end facing away from the fluid outlet portion (19), and a seat (32) being arranged at an axial end of the valve body (12) facing the fluid outlet portion (19). A valve needle (20) is axially movable in the cavity (18) and prevents a fluid flow through the fluid outlet portion (19) in a closing position and releases the fluid flow through the flu- id outlet portion (19) in further positions. The valve needle (20) has an axial end (20a) facing away from the fluid outlet portion (19) and facing the end portion (13), and a seat part (34) resting on the seat (32) of the valve body (12) in the closing position. A contact area between the seat part (34) and the seat (32) of the valve body (12) has a first outer diameter (D1). The valve assembly (11) comprises an electro- magnetic actuator unit (36) being designed to actuate the valve needle (20). A bellow arrangement (24) comprises a bellow (24a) and an end portion (24b), the bellow (24a) is fixedly coupled to the end portion (24b) in a coupling area (25). The coupling area (25) has a second outer diameter (D2). The first outer diameter (D1) is equal to the second outer diameter (D2).

摘要： A valve assembly (1) for a fluid injector is disclosed. It comprises a valve body (3) having a longitudinal axis (L), an armature (9), a valve needle (11) having a needle tip (12) and a damping element (13). The armature (9) and the damping element (13) comprise penetrating first openings (15, 17) respectively, in which the valve needle (11) is arranged. The damping element (13) is fixed to the valve needle (11) and arranged between the armature (9) and the needle tip (12) with respect to the longitudinal axis (L) to attenuate a movement of the valve needle (11) relative to the valve body (3) during the operation of the assembly (1).
