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.
