Claim Text:
1. A fuel delivery device for a fuel injection device of an internal combustion engine, having a supply pump ( 10 ) and at least one high-pressure pump ( 16 ), wherein the supply pump ( 10 ) delivers fuel from a fuel tank ( 12 ) to a suction side of the high-pressure pump ( 16 ) and the high-pressure pump ( 16 ) delivers fuel to a high-pressure region ( 18 ), characterized in that the supply pump ( 10 ) has a variable displacement, wherein the supply pump ( 10 ) has a constant speed of rotation such that the supply pump ( 10 ) is configured to deliver a variable quantity of fuel at the constant speed of rotation, wherein each of a hydraulic line ( 26 ), a suction port ( 56 ), and a delivery port ( 58 ) are coupled to the supply pump ( 10 ), the suction portion ( 56 ) configured to move fuel from the fuel tank ( 12 ) to the supply pump ( 10 ), the delivery port ( 58 ) configured to move fuel from the supply pump ( 10 ) to the high-pressure pump ( 16 ), and the hydraulic line ( 26 ) configured to provide a control pressure to the supply pump ( 10 ), wherein the hydraulic line ( 26 ) is a first hydraulic line, wherein the supply pump ( 10 ) is coupled to the high-pressure pump ( 16 ) via a second hydraulic line ( 6 ), and wherein one end of the first hydraulic line ( 26 ) is coupled directly to the second hydraulic line ( 6 ).
