Abstract (en)
[origin: EP0375928A2] In the case of a fuel injection apparatus with an injection nozzle (3) opening at predetermined pressure, to which fuel can be fed under pressure, the injection nozzle chamber (2) is connected to a fuel feed line (8) by way of an outward closing non-return valve (9), the pressure in the fuel feed line (8) being lower than the opening pressure of the injection nozzle. In addition, the injection nozzle chamber (2) is connected to a working chamber (14) of a spring-loaded working piston (12), the displacement movement of which is brought about by the action of the spring force in order to increase the pressure in the nozzle chamber (2) in excess of the opening pressure of the injection nozzle (1) by relieving a separate working chamber (20) of the spring-loaded working piston (12). <IMAGE>
