US Patent 11591869 Variable flow diverter downhole tool

A downhole tool configured to vary the amount of pressurized fluid delivered to other tools incorporated into a bottom hole assembly, such as a mud motor. The tool comprises an inner element installed within an outer sleeve. The inner element is configured to move between three different positions relative to the outer sleeve. In a first position, pressurized fluid is diverted away from downstream tools within the bottom hole assembly. In a second and third position, pressurized fluid is directed towards downstream tools. Movement of the tool between the different positions is caused by varying external forces applied to the tool.
