Patent ID: 7926569

Claim:
A bypass device for preventing hydraulic lock in a failed hydraulic system, wherein the bypass device comprises: a. an outer tubular body, wherein the outer tubular body comprises a fluid control manifold with a first fluid control path and a second fluid control path, wherein the first fluid control path comprises a top end and a bottom end, and wherein the second fluid control path comprises a top end and a bottom end; b. a first high pressure fluid path, wherein the first high pressure fluid path comprises a first valve, wherein the first high pressure fluid path is in fluid communication with a first high pressure fluid connecting path and the second fluid control path top end; c. a second high pressure fluid path, wherein the second high pressure fluid path comprises a second valve, wherein the second high pressure fluid path is in fluid communication with a second high pressure fluid connecting path and the first fluid control path bottom end; d. an inner tubular body disposed within the outer tubular body; e. a hydraulic piston having a first piston end and a second piston end is disposed within a piston chamber, wherein the piston chamber is disposed between the inner tubular body and the outer tubular body, and wherein the piston chamber comprises: (i) a first chamber section formed between the first piston end and a first seal; and (ii) a second chamber section formed between the second piston end and a second seal; f. a first fluid port in fluid communication with the first fluid control path top end and the first chamber section; and g. a second fluid port in fluid communication with the first fluid control path bottom end and the second chamber section.
