摘要： A high-pressure fuel system for internal combustion engines, having a housing that contains two high-pressure bodies. The high-pressure bodies rest with contact surfaces at least indirectly against each other and are pressed against each other by means of a tensioning device. A supply conduit is embodied in the high-pressure bodies, which carries highly pressurized fuel and passes through the contact surfaces of the two high-pressure bodies. A sealing film is disposed between the two high-pressure bodies, which encompasses the passage of the high-pressure conduit and thus assures a favorable seal.

摘要： A high-pressure fuel reservoir is proposed in which the hydraulic connection between the connection fitting and the reservoir chamber is produced by a number of connecting bores. This reduces the stress peaks in the vicinity of the intersections of the connecting bore and reservoir chamber so that the compression capacity of the high-pressure fuel reservoir increases.

摘要： A fuel injection system for internal combustion engines, in particular Diesel engines, having a fuel reservoir which is supplied from a high-pressure pump and supplies fuel to a number of injectors corresponding to the number of cylinders of the engine, and has a pressure limiting valve, which is connected sealingly to the fuel reservoir, the pressure limiting valve having a valve housing, a high-pressure region, a low-pressure region, a valve seat oriented toward the inlet, an axially displaceable valve body, and a valve spring urging the valve body in the direction of the valve seat. The pressure limiting valve is integrated—at least partially—with the fuel reservoir, in such a way that at least the valve seat and the valve body are spatially associated with the fuel reservoir, and the seal sealing off the pressure limiting valve from the fuel reservoir is associated with the low-pressure region of the pressure limiting valve.

摘要： A method and a device for storing and/or reading out data of a fuel metering system, in particular a fuel pump or an injector, as described. Data on the fuel pump and/or the injector is assigned to at least one electronic component. The data is taken into account by a control unit in controlling the fuel metering system. The component is mechanically and/or electrically connected to the control unit during a first interval of time and is mechanically and/or electrically detached from the control unit and/or the fuel metering unit during a second interval of time.

摘要： The invention relates to a pump, particularly a high-pressure fuel pump, having a drive shaft, which includes a section that is eccentric to the rotational axis thereof and on which a ring is rotatably supported. The pump has at least one pump piston, which is directly supported on the ring via the piston base thereof, or via a support element and is driven in a stroke movement upon the rotational movement of the drive shaft. The ring has an at least approximately planar contact surface in the region of the support of the piston base or of the support element, and the support surface of the piston base or of the support element on the ring is greater than the cross-sectional surface of the shaft of the pump piston. The extension of the support surface of the piston base or of the support element in the tangential direction to the rotational axis of the drive shaft is greater than the extension thereof in the direction of the rotational axis of the drive shaft.
