ABSTRACT:
A return-flow-free fuel supply system for an internal combustion engine having at least one fuel pump for pumping fuel from a first region of a fuel reservoir into a pressure region communicating with a fuel distributor, at least one suction jet pump, through which fuel pumped through a suction jet pump line by means of the fuel pump flows and through which fuel can be pumped from a second region of the fuel reservoir into the first region, at least one means that regulate and/or control the pressure in the pressure region, and at least one check valve, by which at least a portion of the pressure region can be blocked off from the fuel pump. The means that regulate and/or control the pressure in the pressure region include at least one electrically actuatable magnet valve(40,44), which is disposed downstream of the check valve in the suction jet pump line.
