摘要： Provided are a flow volume control device capable of securing a strength withstanding a high fuel pressure, and a method for manufacturing the flow volume control device. A fuel injection valve 1 includes a movable element 102 and a nozzle holder 101 that is positioned on the outer peripheral side of the movable element 102 and holds the movable element 102 inside in a radial direction. The nozzle holder 101 is molded using precipitation hardening stainless steel as a material. In addition, the manufacturing method includes forging and molding a material by forging using the precipitation hardening stainless steel as the nozzle holder 101, performing solution thermal treatment on the material after the forging and molding step, and performing precipitation hardening thermal treatment on the material after the solution thermal treatment, and finishing and molding the material after the precipitation hardening thermal treatment.

摘要： An object of the present invention is to provide a fuel rail which can realize weight reduction while enhancing the strength of a cross-hole portion. A fuel rail for an internal combustion engine according to the present invention includes a cylindrical fuel rail body 1 and an injector mounting portion 2 in which a hole 2d to supply a fuel to an injector is formed, and the injector is mounted. The injector mounting portion 2 is integrally molded in the fuel rail body 1 such that the fuel supply hole 2d crosses a center hole 1a of the fuel rail body 1. plurality of injector mounting portions 2 is included along a longitudinal direction of the fuel rail body 1. A thickness of a root portion of the injector mounting portion 2 is thicker than a thickness of the fuel rail body 1 disposed between two adjacent injector mounting portions 2.

摘要： Provided is a fuel rail that can achieve a reliable seal between a rail main unit and a cup, involving a short welding distance or a reduced amount of a brazing filler metal. In the fuel rail, a rail main unit 2 has a central hole and a rail main unit-side communication hole 10 that provides communication between the central hole and an outside of the rail main unit 2. An injector receiving member 5 has an injector insertion hole 7 into which an injector is inserted. The injector receiving member 5 is mounted in the rail main unit 2 such that the rail main unit-side communication hole 10 and the injector insertion hole 7 communicate with each other. The injector receiving member 5 has an injector receiving member-side communication hole 9 that provides communication between the rail main unit-side communication hole 10 and the injector insertion hole 7. A metal fusion zone 12 is formed, by way of an inside of the injector receiving member 5, in a bond between the rail main unit 2 and the injector receiving member 5, to thereby seal the bond.
