ABSTRACT:
The invention relates to a high-pressure accumulator for fuel injection systems, having a number of line connections corresponding to the number of chambers of an internal combustion engine. The accumulator has an essentially circular cross section delimited by an inner wall. The individual line connections each have a fuel-conveying longitudinal bore and, with the aid of a screw element, are held in a fitting fastened to the outside of the high-pressure accumulator. The screw element presses the respective high-pressure line connection into a seat. The high-pressure accumulator has an oscillation-damping valve integrated into it that includes a closing element, which is acted on by a spring body supported against a shaft connected to the closing element and is optionally supported against the inside of the high-pressure accumulator.
