  • Downhole tools
    Publication number: 20100147531
    Abstract: A fluid operated apparatus in the form of a flow cap, is mounted on an end of a downhole tool or sub, which itself has a screw thread fitting to a further tool, sub or tubular. The cap provides a number of fluid flow channels arranged in a spiral pattern upon the outer surface. The handedness of the channels matches the handedness of the screw thread fitting so that fluid flow from ports in the tool or sub, acts to tighten the screw thread fitting. A water injection valve including a flow cap is described.
