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.
Claims14
A high-pressure fuel reservoir (1) for a fuel injection system for internal combustion engines comprising a uniformly contoured reservoir chamber (5) and at least one connection fitting (2), and a number of connecting bores (8) between the reservoir chamber (5) and each said connection fitting (2), whereby the connecting fitting (2) serves to integrally reinforce the reservoir chamber (5) and thereby mitigate the mechanical stress due to any pressure build up caused by the fuel within the fuel reservoir (1).
