Patent ID: 7730953

Claim:
A control system for controlling first and second hydraulic pressure-controlled devices comprising: a common hydraulic control line in operable association with the first and second pressure controlled device; a first sleeve controller associated with the first pressure controlled device and the common control line to provide selective control of the first pressure controlled device via the control line; a second sleeve controller associated with the second pressure controlled device and the common control line to provide selective control of the second pressure controlled device via the control line; the first and second sleeve controllers each comprising: a housing which defines a piston chamber; a piston member moveably disposed within the housing between a first position wherein the piston member does not block fluid flow between the control line and the associated pressure-controlled device, and a second position wherein the piston member does block fluid flow between the control line and the associated pressure-controlled device; a J-slot indexing mechanism that controls the position of the piston within the chamber; and the first and second sleeve controllers each being operable between a first condition, wherein control of the associated pressure-controlled device is permitted, and a second condition, wherein control of the associated pressure-controlled device is permitted.
