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 fuel injection system having a prefeed pump, through which fuel from a fuel supply container is pumped to a high-pressure pump, and by means of the high-pressure pump, fuel is pumped into a reservoir. Communicating with the reservoir is at least one injector, through which fuel is injected to the engine. A fuel filter is disposed between the prefeed pump and the high-pressure pump. A return line for uninjected fuel leads back from at least one injector into a region upstream of the high-pressure pump. A valve is provided, by which the return line, in a first switching position, at a low fuel temperature, leads to upstream of the fuel filter, between it and the prefeed pump, and by which the return line, in a second switching position, at a high fuel temperature, leads to downstream of the fuel filter, between it and the high-pressure pump.

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 integratednullat least partiallynullwith 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.
