HIGH-PRESSURE BI-DIRECTIONAL SEALING SYSTEM

摘要

A high-pressure bi-directional sealing system having outer support rings (30, 32), annular, axial seals (100, 300) between the outer support rings (30, 32), inner support rings (150, 160) located between the annular, axial seals (100, 300) and a redundant seal (200) that is located between the inner support rings (150, 160). The outer support rings (30, 32), seals (100, 300), inner support rings (150, 160) and redundant seal (200) are located within a space between an outer tube (12) and an inner tube (14) that is telescopicaiiy disposed within the outer tube (12). Seals (100) and (300) are oriented in opposite directions. Specifically, the opening of seal (100) is facing in a first direction and the opening of seal (300) 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.
