Fuel injection system with integrated high-pressure accumulator

A fuel injection system of an internal combustion engine having a high-pressure pump, wherein a high-pressure outlet (4) of the high-pressure pump is connected to a high-pressure accumulator (23), which comprises at least one accumulator outlet (13a, 13b) for connecting to a fuel injector, wherein the high-pressure accumulator (23) is directly adapted to the high-pressure pump, wherein the high-pressure pump comprises a pump housing having a cylinder head (1), in which a pump piston (2) is guided in a cylinder bore, wherein the high-pressure outlet (4) opens into a cylinder head wall (6) of the cylinder head (1) wherein the high pressure accumulator (23) is embodied as a distribution element (8, 8a, 8b) interacting with the high pressure outlet (4) or the cylinder head (1), in such a way that the accumulator outlet (13a, 13b) is aligned in a precisely defined position in which a fuel line of the fuel injector is aligned with the accumulator outlet (13a, 13b), and

• wherein the distribution element (8, 8a, 8b) is of cupped or cylindrical tube-shaped design and in that the distribution element (8, 8a, 8b) is fastened to a connector (7, 7a, 18) arranged on the cylinder head wall (6).
