Abstract

The invention relates to a high-pressure fuel reservoir for a common-rail fuel injection system of an internal combustion engine, having a tubular base body, which has a substantially circular-cylindrical interior disposed centrally with respect to the longitudinal axis of the tubular base body, which interior communicates with a plurality of connection openings. To enhance the high-pressure strength by simple provisions, the cross section of the tubular base body, in the portions in which the connection openings are disposed, is embodied in weakened form.
