Abstract (en)
[origin: WO0218779A1] The invention relates to a method for controlling the opening and closing process of a nozzle needle (7) of an injection valve, comprising a control valve (3). According to the invention, a rapid operation of the nozzle needle (7) with concomitant low leakage may be achieved, whereby a pressure in the control chamber (7) is generated which acts upon the nozzle needle (7) in addition to the pre-tensioning of the spring (10) to close the nozzle needle (7) and that for opening the nozzle needle (7), the additional pressure acting on the nozzle needle (7) is released.
