Abstract (en)
A high-pressure fuel accumulator for common-rail injection systems, comprising a tubular body (24) elongated in a longitudinal direction (A), having a longitudinal cylindrical hole (26) and a plurality of connection holes (28), each connection hole (28) having an internal end (30) open in said longitudinal cylindrical hole (26) and an external end (32) open onto an outer surface (34) of the tubular body (24). The tubular body (24) comprises at least one recess for reduction of the stresses (36) formed in the immediate vicinity of the internal end (30) of each of said connection holes (28), said recess for reduction of the stresses having an extension (L) limited in a longitudinal direction (A).
