Abstract
A downhole torque limiter. The downhole torque limiter may include a tubular housing; a pipe positioned within the tubular housing, the pipe transitioning from a larger inside diameter (ID) to a smaller inside diameter (ID), thereby forming a venturi profile having a first pressure zone (Z) and a second pressure zone (Z); a tubular valve plate radially positioned between the tubular housing and the pipe and rotationally fixed with the pipe; a lower sub rotationally fixed relative to the tubular housing and rotationally coupled to the tubular valve plate via a clutch mechanism; and a valve assembly positioned within a longitudinal opening extending along at least a portion of a sidewall of the tubular valve plate, the valve assembly configured to be activated by a pressure drop created by fluid flowing through the venturi profile.
