Abstract:
A structure wherein a fastener connects one component to another component at an interface, wherein the fastener allows fluid flow between the components while locating the components accurately with respect to each other, the structure comprising:a first bore defined by the one component; a second bore defined by the other component; a first duct in the one component; a second duct in the other component; a pilot of the fastener located at the interface and fitting closely with the bores; a threaded portion of the fastener engaging the first bore; a first reduced-diameter section of the fastener between the pilot and the threaded portion; a first radial gap defined between the first reduced-diameter section and the first bore, the first gap communicated with the first duct; means for closing one end of the second bore; a second reduced-diameter section of the fastener between the closing means and the pilot; a second radial gap defined between the second reduced-diameter section and the second bore, the second gap communicated with the second duct; and a generally axially oriented groove in the pilot communicating the first gap with the second gap.
