Abstract

A high-pressure fuel reservoir is proposed in which the hydraulic connection between the connection fitting and the reservoir chamber is produced by a number of connecting bores. This reduces the stress peaks in the vicinity of the intersections of the connecting bore and reservoir chamber so that the compression capacity of the high-pressure fuel reservoir increases.
