Patent ID: 7275524

Claim:
A return-flow-free fuel supply system ( 1 ) for an internal combustion engine, in particular of a motor vehicle, the system comprising at least one fuel pump ( 8 ), by means of which fuel can be pumped from a first region ( 2 ) of a fuel reservoir into a pressure region ( 12 ) communicating with a fuel distributor ( 18 ), at least one suction jet pump ( 38 ), through which fuel pumped through a suction jet pump line ( 34 ) by means of the fuel pump ( 8 ) flows and through which fuel can be pumped from a second region ( 4 ) of the fuel reservoir into the first region ( 2 ), at least one means ( 20 , 24 , 30 ) that regulate and/or control the pressure in the pressure region ( 12 ), and at least one check valve ( 14 ), by which at least a portion of the pressure region ( 12 ) can be blocked off from the fuel pump ( 8 ), the means ( 20 , 24 , 30 ) that regulate and/or control the pressure in the pressure region ( 12 ) including at least one electrically actuatable magnet valve ( 40 ; 44 ), disposed downstream of the check valve ( 14 ) in the suction jet pump line ( 34 ).
