Abstract
A fuel supply system has a pressure chamber which communicates with a fuel gallery. The pressure chamber receives the fuel from the feed pump or the returned fuel from the fuel gallery. The fuel in the pressure chamber receives heat energy from the engine E so that the fuel is brought into gas-liquid phase. A volume change of the fuel in liquid phase in the fuel gallery can be compensated by a volume change of the fuel in gas phase or gas-liquid phase in the pressure chamber. Thus, the pressure pulsation in the fuel gallery is absorbed in the pressure chamber.
