Patent ID: 7392839

Claim:
A single line sliding sleeve downhole tool assembly comprising: a top sub engaging a top connector which connects to a body that engages a middle connector which is secured to a port housing, wherein the port housing engages a lower connector and the lower connector engages a bottom sub; a sleeve with a production port for axially moving with respect to the body; an annulus port disposed in the port housing for communicating fluid between an annulus and tubing in the sleeve; a first seal assembly providing a sealing engagement between the sleeve and the top connector; a second seal assembly providing a sealing engagement between the middle connector and the sleeve; a third seal assembly providing a sealing engagement between the port housing and the sleeve; a first piston in communication with a fluid source from a single fluid line and wherein the first piston moves axially between at least an original position and at least a secondary position; a second piston in communication with the fluid source from the single fluid line, and wherein the second piston moves axially between at least a second piston original position and at least a second piston secondary position; and wherein the first piston moves the sleeve in a first direction and the second piston moves the sleeve in a second direction; at least one logic drum linearly disposed between the body and the sleeve for rotating and translating alternatingly between the first piston and the second piston; a means for actuating the first piston and the second piston; and a first relocating device for relocating the first piston from the secondary position to the original position and a second relocating device for relocating the second piston from the second piston secondary position to the second piston original position.
