摘要： A blade outer air seal assembly includes a support structure and a blade outer air seal having a plurality of segments extending circumferentially about an axis and mounted to the support structure. At least two segments have a base portion extending from a first circumferential side to a second circumferential side, a first protrusion extending from the first circumferential side and having a first slot, and a second protrusion extending from the second circumferential side and having a second slot. A feather seal is arranged in the first slot and the second slot between the at least two segments such that the feather seal is pivotable between first and second positions in response to relative movement between the first and second protrusions.

摘要： In order to effect a seal a porous material which comprises one side of two opposing surfaces is used to restrict and evenly distribute externally pressurized gas, liquid, steam, etc. between the two surfaces, exerting a force which is opposite the forces from pressure differences or springs trying to close the two faces together and so may create a non-contact seal that is more stable and reliable than hydrodynamic seals currently in use. A non-contact bearing is also disclosed having opposing surfaces with relative motion and one surface issuing higher than ambient pressure through a porous restriction, wherein the porous restriction is part of a monolithic porous body, or a porous layer, attached to lands containing a labyrinth, the porous restriction and lands configured to not distort more than 10% of a gap created from differential pressure between each side of the porous restriction.

摘要： A casing for a rotating machine includes a first fixed segment, and a second segment rotating along an axis of rotation (X-X). The first segment and the second segment are in contact along an interface provided with a sealing element. The sealing element is positioned in a housing connected to the internal volume of the casing, and also to the surrounding medium. The connection between the housing and the surrounding medium is made via a duct. The first casing segment or the second casing segment has a planer positioned at an outer end of the duct.

摘要： A sliding component includes a pair of sliding members being slidable relative to each other on sliding surfaces of the sliding members. One of the sliding surfaces includes a dimple group in which dimples are arranged in a radial direction and a circumferential direction, each of the dimples having an opening portion whose shape has a long axis and a short axis orthogonal to the long axis. A dimple angle formed by a radial axis passing through an intersection of the long axis and the short axis of the dimple and a rotational center of the sliding surface and the long axis changes in at least one of the radial direction and the circumferential direction of the one of the sliding surfaces.

摘要： A sliding component has an annular mating ring and an annular seal ring opposite to each other and causing respective sliding surfaces thereof to slidably rotate relative to each other, to seal a sealed fluid present on radially inner or outer side of the sliding surfaces. In the sliding surface of the seal ring, a plurality of dynamic pressure recesses is formed separately arranged in a circumferential direction, the dynamic pressure recesses generating a dynamic pressure by a relative sliding rotation between the mating ring and the seal ring. In the sliding surface of the mating ring, a plurality of static pressure recesses is formed in the circumferential direction at positions where the static pressure recesses cooperate with the dynamic pressure recesses to enable the sealed fluid to flow the static pressure recesses to the dynamic pressure recesses. The static pressure recesses is deeper than the dynamic pressure recesses.

摘要： The disclosure relates to a mechanical seal for sealing a fluid-conducting channel and/or space extending in a stationary component and/or a rotating component from the environment, having a slide ring which is supported in the axial direction against a counter ring in a sealing manner and, to compensate for wear on its front-end seal face or on a counter face, is supported against the counter ring elastically and movably in the axial direction with this seal face;
having a position sensor to detect the position of the slide ring in the axial direction. The disclosure is characterized in that a temperature sensor is provided on a leakage side of the seal face facing away from the channel and/or space, which sensor at least indirectly detects a temperature which is dependent on the magnitude of a leakage flow passing from the channel and/or space via the seal face.
