A butterfly valve assembly for use in a fluid flow containing particles of debris is provided including a valve element. The valve element has a seal groove that extends about a periphery and defines an upstream side and a downstream side of the valve element. A seal is disposed within the seal groove. A clearance exists between the seal and an edge of the seal groove. Also, a relief is formed in either the valve element or the seal. The particles of debris accumulate in the relief and not the clearance.

Contamination resistant butterfly valve

A gear bearing within a cylinder is provided. The gear bearing comprises an anti-rotation tab comprising a first side and a second side, the anti-rotation tab sitting within a key way of the cylinder. Further, the gear bearing also comprises a first foil extending in a first direction from a first end to the first side of the anti-rotation tab and a second foil extending in a second direction from a second end to the second side of the anti-rotation tab.

Foil bearing with split key

A thrust disc for an aircraft and methods of making and using the thrust disc are provided. The thrust disc includes a planar body, and a region unitarily formed from a portion of the body, wherein the region has a plurality of sides defining the region on the planar body, wherein the region has a textured feature, and wherein a subset of the plurality of sides are cut and at least one of the plurality of sides is integrally connected to the body.

Air bearing-corrugated thrust bearing disc

A gas bearing within a cylinder includes an anti-rotation tab sitting within a key way of the cylinder and a first foil forming an inner loop and an intermediary loop. The inner loop extends in a first direction from a first end to an intermediary portion. The intermediary loop extends from the intermediary to the anti-rotation tab.

Foil bearing with large radius key

A gas bearing within a cylinder is provided. The gas bearing comprises an anti-rotation tab sitting within a key way of the cylinder. Further, the gas bearing comprises a first foil forming an inner loop and an intermediary loop. The inner loop extends in a first direction from a first end to an intermediary portion. The intermediary loop extends from the intermediary to the anti-rotation tab.
