Abstract:
A torque transfer control tool has a rotary-stroking piston that is axially movable within a fluid chamber in response to rotation of mandrel having an upper end co-rotatably coupled to a first torsional drive system component and a lower end coaxially disposed and rotatable within the bore of a cylindrical housing. A lower end of the housing is co-rotatably coupled to a second torsional drive system component. Mandrel rotation in a first rotational direction moves the piston downward to pressurize a fluid in a lower fluid chamber below the piston. Fluid flow control means associated with the piston allows fluid flow out of the lower fluid chamber to prevent the fluid pressure therein from exceeding a first pre-set pressure, thus limiting the magnitude of the torque transferred to the second torsional drive system component in the first rotational direction via the tool housing.

Claim (Index 1):
A tool for controlling torque transfer in a torsional drive system, said tool comprising:\n (a) an elongate mandrel having an upper end, a lower end, and a generally cylindrical outer surface, wherein said upper end of the mandrel is adapted for coaxial and co-rotatable connection to a first torsional drive system component; (b) a generally cylindrical tool housing having an upper end and a lower end, and defining a tool housing bore extending from said upper end at least partially through the housing, wherein:\n the lower end of the mandrel extends coaxially into the housing bore such that the mandrel is rotatable relative to the tool housing; \n the lower end of the tool housing is adapted for coaxial and co-rotatable connection to a second torsional drive system component; \n the tool defines a primary fluid chamber in a region of the tool housing bore not occupied by the mandrel; and \n the mandrel is structurally coupled to the tool housing such that axial loads can be transferred from the mandrel to the tool housing; \n (c) a primary piston having a cylindrical outer surface, said primary piston being sealingly movable axially within the primary fluid chamber such that the primary piston divides the primary fluid chamber into an upper primary fluid chamber above the primary piston and a lower primary fluid chamber below the primary piston, with the respective volumes of the upper and lower primary fluid chambers varying with the axial position of the primary piston, and with at least one of the upper and lower primary fluid chambers being configured to provide pressured fluid containment; (d) fluid communication means, for enabling fluid communication out of at least one of the upper and lower primary fluid chambers at a selected pressure; and (e) piston actuation means whereby rotation of the mandrel in a first direction will cause downward movement of the primary piston within the primary fluid chamber, and whereby rotation of the mandrel in a second direction will cause upward movement of the primary piston within the primary fluid chamber; wherein:\n (f) downward movement of the primary piston will tend to expel fluid present in the lower primary fluid chamber; and \n (g) upward movement of the primary piston will tend to expel fluid present in the upper primary fluid chamber.
