ABSTRACT:
The opening and closing movement of a injector valve member (32) which closes and temporarily opens discharge orifices (52) communicating with the combustion chamber of an internal combustion engine, for example a diesel engine, is controlled by the fuel pressure in a control chamber (42) arranged at one end of the injector valve member (32). The fuel pressure in said control chamber (42) is controlled by two orifices (26,38) communicating with one another. One of the orifices (38) is connected to a high pressure fuel inlet (12). The other orifice (26) is closed at one end by a solenoid operated pilot valve (72). Opening of the latter results in a single fuel jet passing through the orifices (26,38) which causes the opening of the injector valve member (32).
