Abstract
A drilling motor provides rotational force within a wellbore and includes a power section within the interior of a housing, a rotor positioned within the power section, and a passage within the rotor. The passage is configured to bypass a portion of the drilling mud from above the power section within the interior of the housing to below the power section within the interior of the housing, and an interior valve at a downstream end of the passage, wherein the valve includes a rupture disc configured to close the passage when the pressure from the drilling mud is less than a threshold pressure, and to rupture to open the passage and pass the drilling mud through the valve when the pressure from the drilling mud is greater than the threshold pressure.
