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 15):
A tool as in  claim 1 , further comprising a secondary piston axially movable within a secondary fluid chamber formed below the primary fluid chamber, wherein the secondary piston is rotatably engageable with the mandrel such that:\n (a) rotation of the mandrel in a first direction will cause downward movement of the secondary piston within the secondary fluid chamber; (b) rotation of the mandrel in a second direction will cause upward movement of the secondary piston within the secondary fluid chamber; (d) downward movement of the secondary piston will tend to expel fluid present in the lower secondary fluid chamber; and (d) upward movement of the secondary piston will tend to expel fluid present in the upper secondary fluid chamber.
