Document Type and Number:
WIPO Patent Application WO/2017/094359
Kind Code:
A1
Abstract:
[Problem] To make it possible, in the event of a future pressure increase in a gasoline direct-injection system, to prevent breaking of a brazed section without increasing the thickness of a rail body even when the rail body and an end cap are fixed by brazing. [Solution] A gasoline direct-injection rail in which end caps 2 are inserted/placed inward at both ends of a rail body 1, and the outer periphery 3 of the end caps 2 and the inner periphery 4 of the rail body 1 are fixed by brazing, wherein the outer periphery 7 of the rail body 1 is provided with a reinforcing ring 6 having an axial length L of L ≥ 5 mm, one end 10 of the reinforcing ring 6 on the end cap 2 side is positioned so as to not overlap a brazed section 12 of the rail body 1 and the end cap 2, the distance X from the one end 10 of the reinforcing ring 6 to the tip 13 of the brazed section 12 is 0 mm ≤ X ≤ 15 mm, and the thickness of the reinforcing ring 6 is at least 40% of the thickness of the rail body 1.
