A valve device (100) is described for conveying a liquid having a housing (110), a valve needle (120) which is arranged such that it can be deflected in a valve-needle chamber (113) of the housing (110), and a drive device (200) for the valve needle (120), wherein the drive device (200) comprises an electric drive component (210) which brings about a direct deflection of the valve needle (120). Furthermore, the drive device (200) comprises a hydraulic drive component (220) which can be activated in addition to the electric drive component (210) and brings about a ballistic deflection of the valve needle (120). |
