    摘要： The invention relates to a fuel injector comprising a nozzle retainer or an injector body, a valve body and a nozzle body, in which a preferably needle-shaped injection valve member is arranged to be vertically movable, said member releasing or closing at least one injection port leading to a combustion chamber of an internal combustion engine depending on the pressure relief of or the pressure load on a control chamber. The invention is characterized in that a valve comprising a preferably ball-shaped valve element is arranged in the nozzle retainer or in the injector body for the pressure relief of the control chamber.

    摘要： The invention relates to an injection nozzle (1) for an internal combustion engine, particularly in a motor vehicle. Said injection nozzle (1) comprises a first nozzle needle (2) for controlling at least one first injection port (5) and a second nozzle needle (3) for controlling at least one second injection port (15). A nozzle chamber (11) can be connected to a high pressure source (28) via a fuel supply line (27). The first nozzle needle (2) is provided with a first pressure stage (12) which is disposed in the nozzle chamber (11) and can be impinged upon therein by an injection pressure that applies an opening force acting in the opening direction (13) to the first nozzle needle (2). In order to improve closing of the first nozzle needle (2), a control chamber (38) is provided which can be connected to the high pressure source (28) via a control line (39). The first nozzle needle (2) encompasses a first control surface (41) which is located in the control chamber (38) and can be impinged upon therein by a control pressure that applies a closing force acting in the closing direction (7) to the first nozzle needle (2). The control line (39) is more severely throttled than the fuel supply line (27).

    摘要： The invention relates to a fuel injection valve comprising two injection valve members (28, 128), a second injection valve member (128) being displaceably guided in a hollow first injection valve member (28). The first injection valve member (28) enables at least one first injection opening (32) to be controlled by means of a sealing surface (34) arranged on said valve member, in conjunction with a valve seat (36), and the second injection valve member (128) enables at least one second injection opening (132) to be controlled by means of a sealing surface (134) arranged on said valve member, in conjunction with a valve seat (136). Said fuel injection valve comprises a pressure chamber (40) connected to a high-pressure source (10, 22), and the injection valve members (28, 128) are subjected to the pressure in the pressure chamber (40) on a pressure surface (42; 142) in the closing position thereof, and can be displaced against a closing force in an opening direction (29). A control piston (147) defining a control chamber (50) is associated with the second injection valve member (128) and exerts a force on the second injection valve member (128) in the opening direction (29) by means of the pressure in the control chamber (50). The control chamber (50) is connected to the high-pressure source (10, 22).
