US Classification:

55406, 55407, 55408, 55400, 55409, 95241, 95261, 95266, 95270, 96155, 96187, 96193, 96194, 96214, 96206, 96208, 138 89, 184 626, 184 112, 184 621, 184 623, 184 624, 60 3908, 4151691

Abstract:

The present invention provides a free vortex air-oil separator that may be used in systems for separating oil from air oil mixtures. The free vortex air-oil separator comprises a free vortex chamber having a first chamber wall, a second chamber wall located axially aft from the first chamber wall and a rim located in a radially outer region from an axis of rotation, a plurality of vent holes in the rim and a cavity formed by the first and second chamber walls, and the rim, wherein a free vortex is created when there is a flow into the cavity through the plurality of vent holes.

US Classification:

384475000

Abstract:

A device and method for uniformly providing lubricant to rotating machine parts is provided. The device comprises an axially mounted rotating circumferential lubricant reservoir with a weir comprising one side of the lubricant reservoir. The reservoir and weir are disposed at uniform radius and circumferentially about an axis of rotation causing lubricant added to the reservoir to flow uniformly over the weir about the circumference of the weir when the device is in high speed rotational motion. Because of the uniform flow of lubricant over the top of the weir around the circumference of the weir, lubricant can be directed to machine parts requiring lubrication in a uniform manner around the circumference of the moving device.

International Classification:

F01D 25/18

Abstract:

An apparatus and system for injecting fluid into a boundary layer of a flow of fluid are provided. The boundary layer injection insert assembly includes an insert body and a central bore extending through the insert body from an inlet opening positioned at a first end to an outlet opening positioned at a second end of the insert body opposite the first end. The insert body is approximately cylindrical about a longitudinal axis and includes a thickness in a radial direction orthogonal to the longitudinal axis. The first end includes a plurality of injection holes extending through the thickness for a first distance, the first distance being less than the length. The boundary layer injection insert assembly also includes an annular spacer at least partially surrounding the second end and including a radially inner surface and a radially outer surface spaced apart by a thickness of the annular spacer.
