STRUCTURAL MEMBER BEARING INNER PRESSURE, ESPECIALLY USED FOR FUEL INJECTION DEVICE IN INTERNAL COMBUSTION ENGINE WITH HIGH PRESSURE FUEL PUMP

摘要

PROBLEM TO BE SOLVED: To further improve the strength of a hole intersection portion of a structural member against inner pressure load, when caused.

SOLUTION: For the purpose of the local existence of a great radius of curvature for distributing pressure stress caused in the maximum loaded position, an elliptical cross section 6 is formed in an intersection area 5 between both holes 3, 4.
