    摘要： A fuel tank having an inlet and an outlet is connected to a separate pressure vessel by means of a pump. Fuel vapors are pumped out of the tank and into the pressure vessel while the tank is being filled via the inlet, so that fuel vapors cannot escape during filling. After filling, the inlet is closed and the pressure in the tank is increased to about 4 bar by means of a pressure regulator in a line connecting the pressure vessel to the fuel tank. The pump is then switched off and the fuel can be delivered to the engine via the outlet under the increased fuel pressure in the tank, the pressure being reduced to fuel system pressure by a pressure regulator in the outlet line.

    摘要： A device (1) for supplying electric current to the fuel pump (2) of a motor vehicle internal combustion engine (3) comprises a DC/DC converter (13) which increases voltage to a predetermined value in the event of a voltage drop of a direct current source (7). This ensures an adequate voltage supply of the fuel pump (2) even at low voltages of the direct voltage source. When the voltage (15) of the direct voltage source (7) is sufficient, the DC/DC converter (13) is bridged, so that the fuel pump (2) is directly supplied with fuel from the direct voltage source (7). The DC/DC converter is also bridged when the device is faulty.
