Manufacturing method of the common rail common rail, common rail and holder,

摘要

A common rail that is formed by bonding the rail holder by using a liquid phase diffusion bonding of heat and pressure bonding, with a bonding and convex pressing surface and the common rail body, the present invention, H the height of the bonding convex But to meet the 1μm ≦ H ≦ 50μm, the common rail holder provides a common rail area of ​​the cross-section parallel to the pressing surface has a deformation guide portion smaller than the area of ​​the pressing surface.
