Fuel system for combustion engine, has pressure relief vent provided as channel-like connecting channel in seal seat of pressure limiting valve, and is designed such that connecting channel is opened during closed pressure limit valve
The fuel system has a mechanically working pressure limiting valve, whose valve body (3) is pressed against a seal seat (1) by a spring element (2), where a fuel-high pressure area (H) lying between a high pressure pump and an injection valve is opened when exceeding the threshold pressure, such that the fuel is discharged into a fuel-low pressure area (N). A pressure relief vent is provided as channel-like connecting channel (5) in the seal seat of the pressure limiting valve, and is designed in such a way that the connecting channel is opened during closed pressure limit valve.
