Abstract
A downhole tool includes a tool body, stator, and rotor. The tool body is aligned along a tool centerline and includes an aperture therethrough operable to pass a fluid to an exterior of the body. The stator is fixed relative to the tool body and includes a fluid flow restriction operable to pass at least a portion of the fluid from an interior of the stator to the exterior of the body at an adjustable flow rate. The rotor is disposed within the tool body and rotatable relative to the stator and includes an exhaust port selectively aligned with at least one aperture through the tool body by rotation of the rotor relative to the stator. The exhaust port is operable to pass at least a portion of the fluid from an interior of the rotor to the exterior of the body when aligned with the aperture.
