IPC: F02M61/18
Filed: 1999-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a valve device capable of improving valve density, a fuel injection device and manufacturing method therefor. SOLUTION: At the time of a valve closing state in which a nozzle body 20 and a valve needle 30 are assembled and a valve seat part 21 and an abutting part 31 are abutted, load is applied to the abutting part 31 side in an axis direction from a non-abutting part side of the valve needle 30. When load is applied, the abutting part 31 is bitten into the valve seat part 21, and the valve seat part 21 and the abutting part 31 are deformed. By deformation of the valve seat part 21 and the abutting part 31, a groove part 22 is formed in the valve seat part 21 and the abutting part 31 is formed into an external shape corresponding to the shape of the groove part 22. As a result, the shape of the groove part 22 and the external shape of the abutting part 31 are leveled and a gap is not generated between the valve seat part 21 and the abutting part 31.  Therefore, valve density when opening a valve is improved and fuel can be prevented from leaking into a combustion chamber at the time other than prescribed time.
