Abstract
A laminar flow tool is for channeling water, air or other fluids through a down drill pipe or tubing for pressurization of other tools or other purposes. The tool provides a flow divider having an 180 degree twist separating a driven fluid chamber from a buffer fluid pocket. Fluid in the tool is calmed as it travels and loses some of the spin (“turbulence”) inherent in the water or other fluid. A buffer pocket on one side absorbs shocks and stabilizes the driven side. Ports in the buffer side help equalize pressure.
Claims6
A laminar flow tool, comprising:
- a central sleeve having a housing defining an inlet and an outlet and defining a central bore connecting said inlet and outlet for receiving a fluid flow therethrough;
- a central divider dividing said central bore into a driving fluid chamber and a buffer chamber;
- said central divider formed by an elongated sheet having a twist about its elongated axis at least 45 degrees to impart a rotational component to fluid flowing through said driving fluid chamber;
- a buffer flow diverter provided downstream of said buffer chamber and cooperating with said central divider to provide smaller outlet to said buffer chamber than an outlet of said driving fluid chamber.
