Fuel high pressure reservoir manufacturing method for fuel injection system, involves forming reservoir from massive metallic cylindrical blank by spin extrusion, where reservoir comprises specific inside diameter

摘要

The method involves forming a fuel high pressure reservoir from a massive metallic cylindrical blank (1) by spin extrusion. A cover is provided as an integral component of the fuel high pressure reservoir that comprises an inside diameter of maximum 15 millimeters, where wall thickness of the reservoir is different from its length. The reservoir has a specific length, where the length and the diameter are in a specific ratio.
