  • STRESS RELIEF IN PRESSURIZED FLUID FLOW SYSTEM
    Publication number: 20110297256
    Abstract: A method of reducing tensile stress within a drilled element 100 at an intersection 130 between a primary bore 110 and a secondary bore 120 comprises the following steps. A first face of the drilled element 100 is loaded with a first loading element. A compressive hoop stress is generated where the first face of the drilled element 100 is loaded by the first loading element, and the intersection 130 is sufficiently close to the first face of the drilled element 100 such that the compressive hoop stress counteracts tensile stress in the drilled element 100 at the intersection 130. A suitable drilled element 100 and fluid flow systems, such as a fuel injector, including such a drilled element 100 are also described.
