摘要： In a method for reducing “blow-out” of annular welds for attaching components in a fuel injector, a relief region is formed on radially-facing surfaces of the components. The relief region is adjacent to a press-fit region. The components are then pressed together, and a weld is made in the relief region. A sealed gap is thereby formed in the relief region between the weld and the press-fit region. The sealed gap provides for the expansion of trapped gases that could otherwise “blow out” the liquid weld bead.

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.
摘要翻译：公开了一种用于减少环形焊缝的“吹出”的方法，用于将压配合部件附接在燃料喷射器组件中。该方法采用多步焊接程序，由此相对于围绕纵向轴线的组件的小于360°的旋转相对应的第一环形焊道留下径向空隙，其随后用第二环形焊道密封。在替代实施例中，在部件的径向对置的表面上形成凸起区域，所述浮雕区域邻近压配合区域设置。因此，在焊接部和压配合区域之间的释放区域中形成密封间隙。密封的间隙提供了另外的用于膨胀被捕获的气体的手段，否则可以“吹出”液体焊道。

摘要： A fuel injector having a housing, an armature, and an inlet member, and a needle. The housing has a fuel inlet, a fuel outlet, and a fuel passageway extending from the fuel inlet to the fuel outlet along a longitudinal axis. The inlet member is disposed within the fuel passageway. The armature is also disposed within the fuel passageway. The needle is operatively connected to the armature, and is positionable to permit or inhibit fuel flow through the fuel outlet. A first surface is located on one of the inlet member or the armature. The first surface has a first perimeter located on a first plane that is substantially perpendicular to the longitudinal axis. A second surface, which is exposed to the first surface, is located on the other of the inlet member and the armature. The second surface has a second perimeter at least partially located on a second plane that is oblique to the longitudinal axis. The first surface and the second surface provide a method of mechanically enhancing motion of components of a fuel injector. The method is achieved by engaging the first surface and the second surface so that the central axis of the armature and needle assembly is at least partially offset from the longitudinal axis of the fuel injector.
