Abstract: A porous media ventless thrust bearing seal is disclosed. The porous media thrust bearing may include a primary porous media thrust bearing also serving as a seal ring including porous media positioned over a plenum and a port connected to the plenum, and conductive passages for communicating pressurized fluid to the plenums through the ports of the primary ring. The porous media ventless thrust bearing may also include a treated process gas supplied to a port which is closest to the untreated process gas, at a pressure which is higher than the untreated process gas. An inert gas (or fluid in a liquid state) may be supplied to the remaining port, at a pressure which is the same as the untreated process gas. A certain amount of treated process gas may flow into the untreated process gas, and may prevent the untreated gas from entering the porous media seal.

Abstract: A gas separation device is disclosed. In particular, seal assemblies and adsorbent element constructions for a gas separation device such as a pressure swing adsorption device are disclosed. The seal assembly can be part of a rotary valve and can include a seal backer and a floating seal positioned within a bore in the seal backer.

Abstract: A shaft seal for sealing a gap between a shaft and a casing is provided. The shaft seal includes a plurality of sealing modules, at least one fluid feed and at least one fluid outlet. The sealing modules include an outer main seal, and inner main seal and a fluid drain between the two. Conventional shaft seals of the above type require significant amounts of additional barrier fluid in regular intervals to ensure suitable pressure gradients. In the presently provided shaft seal, the inner seal is designed as a radial double seal which is defined by two gas seals having respective rotating sealing surfaces and stationary sealing surfaces, the pair of sealing surfaces being opposite each other in a sealing plane. The sealing planes extend from the shaft in a substantially radial manner.

Abstract: A pneumatically controlled, two part, rotational face seal is disclosed that has dual modes of operation. There is a first, static mode where a face of each of the two parts of the seal touch each other and provide an air, liquid and water vapor tight, very low leakage rate with high rotational friction between the two parts of the seal. In the second, dynamic mode wherein the two parts of the seal are separated by inert gas and the face seal functions as a gas bearing having very low rotational friction as the two parts are rotated with respect to each other. One part of the seal may be attached to a rotatable turret and the other part may be attached to a base on which the turret is mounted.

Abstract: A gas seal for aerospace engines has a stationary seal housing, a rotating seal plate mounted on the engine drive shaft and a carbon ring seal movably supported in the housing with a face which mates with the face of the seal plate to create a gas seal therebetween. A plurality of flexible pins have first ends supported on the housing and second ends slidably connected with the carbon ring seal to permit the latter to shift axially. A plurality of compression springs bias the two seal faces together. The housing has a first twist lock which selectively engages a second twist lock on the carbon ring seal to movably retain the latter in the housing. The second ends of the spring pins resiliently deflect during mutual rotation of the carbon ring seal and the housing to facilitate engagement and disengagement of the first and second twist locks.
