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 1):
A 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, wherein the sub is configured to allow a fluid to flow through the cavity from the first open end toward the second open end; a piston disposed at least partially within the cavity, the piston having an orifice through which the fluid can flow; and a biasing member exerting a force on the piston directed toward the first open end; wherein the piston is movable between a first position and a second position, in the first position the piston covers the at least one port, thereby preventing the fluid from flowing through the at least one port, and in the second position the at least one port is uncovered and at least a portion of the fluid can flow through the at least one port, and wherein the piston is configured to be in the first position when the fluid flows at a first flowrate and in the second position when the fluid flows at a second flowrate, wherein the second flowrate is greater than the first flowrate.
