Abstract
In one embodiment, the invention is directed to a high-pressure bi-directional sealing system having circumferentially extending outer support rings (), annular, axial seals () between the outer support rings () and a circumferentially extending inner support ring () located between the annular, axial seals (). The outer support rings (), seals (), and circumferentially extending inner support ring () are located within a space between an outer tube () and an inner tube () that is telescopically disposed within the outer tube (). Seals () and () are oriented in opposite directions. Specifically, the opening of seal () is facing in a first direction and the opening of seal () is facing in a second direction that is opposite the first direction. This configuration enables the high-pressure bi-directional sealing system to handle pressure in both directions.
