摘要： The invention relates to an injector for injecting fuel into a combustion chamber of an internal combustion engine. According to the invention, an injection valve member, which opens or closes at least one injection opening, is controlled by a control valve. The control valve opens or closes a connection from a control chamber into a fuel return line by the positioning of a closing element in a seat or by the opening of the seat. A bore is embodied in the closing element, and a pin is received in the bore. The diameter of the bore essentially corresponds to the diameter of the seat. The pin is supported on one side against a pressure rod, against a spring seat, or against the injector housing.

摘要： An arrangement with a piezoelectric actuator is disclosed, made up of a piezoelectric element with a multilayer construction of piezoelectric layers. The piezoelectric actuator is surrounded by an inner chamber at least surrounding the layers, which filled with a fluid insulation medium. The inner chamber is sealed from a fluid medium in an outer chamber an elastic sleeve which can change shape. The sleeve is sealed with sealing elements being provided at the axial ends thereof in the region of an actuator base and an actuator head. By a shape and/or positional change of the sealing elements, corresponding to the elasticity of the sleeve, a volume equalization in the inner chamber with the insulation medium is achieved.

摘要： The invention relates to a fuel injector for injecting fuel into a combustion chamber, having a solenoid valve for controlling a mini-servo valve. A movable armature can be placed in a sealing fashion on a valve seat in a lower armature chamber, wherein in addition the mini-servo valve is held in an injector body and seals a control line against a flat seat. By means of the flat seat, during an actuation of the solenoid valve, the control line can be relieved of pressure from a high fuel pressure to a return pressure into at least one return line. A mechanism for reducing pressure oscillations are provided in the at least one return line, which includes at least one diaphragm cell which is held in a recess and which is placed in fluidic connection with the at least one return bore. A fuel injector with the mechanism for reducing pressure oscillations is therefore created in the at least one return line which operates without a leakage flow and has a simple and effective function.
