Abstract:
Circulation Subassembly The present invention relates to acirculation subassembly (circsub) for incorporation in a drill pipe. The circsub has a flow through condition in which the circsub allows fluid to flow through a bore of the circsub and does not allow fluid communication between the bore of the circsub and an annulus located outside the drill pipe, a partial bypass condition in which the circsub allows fluid to flow through the bore of the circsub and allows fluid communication between the bore of the circsub and the annulus, and a full bypass condition in which the circsub does not allow fluid to flow through the bore of the circsub and allows fluid communication between the bore of the circsub and the annulus. An actuator is provided to change the circsub between conditions under the control of a controller.

Claim (Index 31):
The valve assembly as claimed in  claim 27 , wherein the actuation assembly comprises a control arm and a key, wherein:\n movement of the control arm relative to the piston causes the valve to change between the first condition to the second condition; when the piston is in the first position or the second position the key is located between a recess in the control arm and a recess in the piston, thereby preventing relative movement between the control arm and the piston; movement of piston from the second position to the third position causes the key to move within the recess in the control arm to a position in which the key is located between the recess in the control arm and a recess in the sleeve and subsequently causes the control arm to move relative to the piston; and movement of piston from the third position to the second position causes the control arm to move relative to the piston and subsequently causes the key to move within the recess in the control arm to a position in which the key is located between the recess in the control arm and the recess in the piston.
