Fluid Rotary Type Patents (Class 175/107)
  • Patent number: 11332978
    Abstract: A rotary transfer mechanism is disclosed for a motor, pump, or other downhole tool that accommodates the eccentric motion of a rotor without the need for a flex shaft, articulating joint or CV joint. In one configuration, the rotor is coupled to the drive shaft at a radial offset from the drive shaft axis. The orbiting motion of the rotor, rather than rotation of the rotor about its own axis, generates a torque on the drive shaft, by applying a tangential force to the drive shaft at the location of the radial offset. The radial offset may be set equal to the orbital radius so that no radial movement or flex is required at the drive shaft to accommodate the eccentric rotor movement.

When no blocking implement is retained in the rotor assembly, the fluid passage permits flow of drilling fluid entering the receiving end to the fluid passage of the rotor body. The fluid thereby bypasses the motor, which is not activated. When a blocking implement is in place, drilling fluid flows around the ball catch component and into the motor to thereby activate the motor.

  • Patent number: 10487602
    Abstract: A well tool apparatus comprises a control arrangement configured to control response of the downhole tool by varying a bore-annulus pressure difference. The control arrangement includes a valve piston longitudinally slidable in a generally tubular controller housing that is in operation substantially co-axial with the wellbore, to open or close a valve port to a fluid flow connection between the drill strings interior and the tool. A latch mechanism is configured to latch the valve piston against movement in one axial direction, keeping the valve piston in an open or a closed condition. Unlatching of the valve piston requires displacement thereof in the other axial direction to a mode change position. A stay member is automatically displaceable under hydraulic actuation responsive to bore-annulus pressure differences above a trigger threshold value, to obstruct movement of the latched valve piston under hydraulic actuation to the mode change position.

  • Patent number: 10465510
    Abstract: A rotor catch assembly for connection in a workstring in a wellbore is provided. The rotor catch assembly is connected to a downhole motor assembly that includes a rotor that is driven by a fluid. In the normal operating state of the rotor catch assembly, fluid flows through the catch assembly and causes the rotor to rotate. In this state, the catch assembly generates pressure pulses in the fluid in the workstring to facilitate advancement of the workstring in the wellbore. In the event of a failure of a mechanical connection in the motor assembly, the rotor catch assembly shifts to a catch-activated state in which the motor assembly is disabled.

  • Patent number: 10407776
    Abstract: A method and system for die compensation and restoration uses high-velocity oxy-fuel (HVOF) thermal spray coating and plasma ion nitriding to compensate for a particular part (damaged part) of a press die that causes formation of fine curves at a door of a vehicle to restore it to its original state. A coating thickness quantification technique may precisely compensate for the damaged part of the die that causes formation of the fine curves at the door of the vehicle in a circular form using HVOF thermal spray coating. A surface of the die may be nitrided using plasma ion nitriding after HVOF thermal spray coating is performed, so as to harden the surface of the die so that wear resistance and fatigue resistance of the die can be greatly improved and the hardfacing or overlay welding efficiency of the die can be increased.
