摘要： A fuel injector apparatus and method is provided for use in a fuel injection system of an internal combustion engine that includes a body, a valve seat, closure member, and an orifice plate. The valve seat comprises the intersection of two angled surfaces with a radius before assembly of the fuel injector. During assembly of the fuel injector, a member presses against the radius edge of the sealing surface of the valve seat to create an oblique third sealing surface or sealing band that is coined into the valve seat. The sealing band provides an improved seal between the valve closure member and the valve seat which operates to prevent leakages of fuel in the fuel injector.

摘要： A first laser working method includes a step of irradiating the metallic work held by a rotation holding mechanism, with a nanosecond laser beam from a first laser oscillation mechanism, to form a through hole, and a step of irradiating, when the metallic work is rotated under the action of the rotation holding mechanism, the inner wall of the through hole with a picosecond laser beam from a second laser oscillation mechanism, thereby to finish the same. While forming the through hole, metal vapor is sucked from the outside of the metallic work. Then, the gas is fed from the outside of the metallic work, and the inside of the metallic work is suctioned. In a second laser working method, when a lower hole made through is radially enlarged, the exit side of the lower hole is kept lower in pressure than the laser incident (or entrance) side.

摘要： In a method for injecting fuel into the combustion chamber of an internal combustion engine, the fuel is fed by at least one prefeed pump from a tank to at least one high-pressure pump and the high-pressure fuel fed by the high-pressure pump is supplied to the injector, wherein the injector has an injection nozzle with an axially movable nozzle needle protruding into a control chamber which can be fed with fuel under pressure and whose pressure is controlled by a control valve which opens or closes at least one inflow or outflow duct for fuel. Between the prefeed pump and the high-pressure pump, a partial volume of the fuel is branched off as a flushing volume and supplied to a flushing channel of the injector, wherein the flushing volume is directly supplied to the control valve such that the flushing volume flows at least partially through the control valve and preferably mixes with the fuel from the inflow or outflow duct, respectively.

摘要： A method for reducing “blow-out” of annular welds for attaching press-fit components in a fuel injector assembly is disclosed. The method employs a multi-step welding procedure whereby a first annular weld bead that corresponds to less than 360° of rotation of the assembly about a longitudinal axis leaves a radial void that is thereafter sealed with a second annular weld bead. In an alternative embodiment, a relief region is formed on radially-facing surfaces of the components, the relief region being disposed adjacent to a press-fit region. A sealed gap is thereby formed in the relief region between the welds and the press-fit region. The sealed gap provides a further means for expansion of trapped gases that could otherwise “blow out” the liquid weld bead.

摘要： A variable shim and valve seat assembly for applications in a solenoid actuated fuel injector includes a variable shim having a face, a valve seat having a top surface that interfaces with the face, and mating features integrated in the face of the variable shim and the top surface of the valve seat. The mating features provide axial displacement of the valve seat through rotation of the valve seat relative to the variable shim. The mating features may be ramped surfaces. The amount of seat displacement is dependent on the designed ramp angle, the number of ramps, and the degree of rotation. Once the desired valve stroke is set, the seat is welded to the injector body to achieve a leak free interface. Tight stroke setting tolerances can be achieved by applying an axial load to the seat during stroke setting and welding.
