| 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.
