Abstract

A valve assembly (10) for a fluid injection valve (1) is specified. It comprises a valve body (20), a valve needle (30) comprising a disc element (32), and a driving device (40) for axially displacing the valve needle (30) in an open-ing direction (D) solely by means of hydraulic interaction. The driving device (40) is axially moveable relative to the valve body (20) and to the valve needle (30). The disc element (32) and the driving device (40) have coupling surfaces (321, 401) having an overlapping area of at least 35 % of the cross-sectional area of the cavity (22) of the valve body (20). The coupling surface (401) of the driving device (40) is operable to engage in a form-fit connection with the coupling surface (321) of the disc element (32) for pushing the valve needle (30) towards the closing position.
