Abstract (en)

[origin: EP1925812A1] The valve has a nozzle body (12) into which a valve needle (5), which is controlled by a control valve (4) and with two guidance sections (13,14) is axially movably guided. A valve seat is formed on a front surface (8) of the valve needle on the valve seat side. Pressure surfaces, which act in an opening direction of the valve needle, are formed by a pressure surface, which is designed at the front surface and a pressure switch, which points into a control space. The pressure in the control space is controlled by the control valve for opening the valve needle.
