Abstract: The present invention is directed to a high-pressure bi-directional sealing system having circumferentially extending outer support rings (1520, 1900), annular, axial seals (1600, 1800) between the outer support rings (1520, 1900) and a circumferentially extending inner support ring (1700) located between the annular, axial seals (1600, 1800). The outer support rings (1520, 1900), seals (1600, 1800), and circumferentially extending inner support ring (1700) are located within a space between an outer tube (1502) and an inner tube (1504) that is telescopically disposed within the outer tube (1502). Seals (1600) and (1800) are oriented in opposite directions. Specifically, the opening of seal (1600) is facing in a first direction and the opening of seal (1800) 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.

Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid.

Abstract: A filter cartridge constructed to prevent an enclosed pleated filter from collapsing into the through-bores formed in a rigid core in high differential pressure applications. The core is modified with reduced-dimension bores to reduce the area of filter material not supported by the core. Alternatively, or in addition, a semi-rigid or rigid core wrap is superposed about the core to add further structural support to the pleated filter. The wrap is formed as a webbed structure with the thickness and spacing of the webbing segments adjusted to partially occlude the underlying core though-bores. This reduces the effective cross-sectional diameter of the through-bores to reduce the overall area of the pleated filter unsupported by the core. The through-bores may have modified shapes to maintain the area of the through-bore and reduce the distance of the through-bore center point from portions of the core wall defining the through-bore. The core also may be modified with clustered through-bores regions.
