Abstract:
A pressure activated cyclical valve assembly includes a first sub, a second sub, a piston, and a biasing member. The first sub has a first passageway therethrough. The second sub is coupled to the first sub and has a second passageway therethrough. The piston is positioned within the second passageway and is shiftable between a deactivated position in which a bypass port is closed and an activated position in which the bypass port is open. The piston has a piston orifice and the first passageway is in fluid communication with the second passageway through the piston orifice. The biasing member exerts a force against the piston to maintain the piston in the deactivated position. The piston orifice is sized to restrict the flow of fluid therethrough such that the piston can be shifted between the deactivated and activated positions by changing flowrate of fluid in the first passageway.

Claim (Index 15):
A method of bypassing fluid in a drillstring assembly, comprising:\n providing a pressure activated cyclical valve assembly in a drillstring, the pressure activated valve assembly comprising:\n a sub having a sidewall extending between a first open end and a second open end, the sidewall defining a cavity between the first open end and the second open end and also defining at least one port passing through the sidewall and in communication with the cavity, \n a piston disposed at least partially within the cavity, the piston having an orifice; and \n a biasing member exerting a force on the piston directed toward the first open end; and \n moving the piston from a deactivated position to an activated position by increasing flowrate of a fluid through the cavity and the orifice to increase pressure on the piston to counteract the force exerted by the biasing member and move the piston from the deactivated position to the activated position.
