摘要： A seal assembly for use in a gas turbine engine includes a first component, a second component, and a sealing unit. The first component is spaced apart from the second component to form a gap therebetween. The sealing unit is positioned in the gap between the first and second components to block liquids and/or gasses from traveling through the gap.

摘要： In sealing arrangement 41 between first and second relatively rotatable bodies of a machine such as a steam turbine, a relatively high pressure p0 exists on one side of the sealing arrangement and a relatively low pressure pf exists on the other side. The sealing arrangement comprises a series of sealing elements or units S1, S2, S3, at least one of which comprises a brush seal. A seal bypassing device, preferably comprising a pressure relief valve 42-44 limits the pressure drop across the brush seal.

摘要： Hydrogen gas is circulated to cool an electric rotating machine main body, and brush seals are provided to contact a predetermined position on the outer circumferential surface of a rotating shaft. As a result, contact of a sealing oil and the hydrogen gas, contact of a lubricating oil and the sealing oil in the bearing, and leakage of the hydrogen gas outside the machine are prevented.

摘要： A sealing arrangement for sealing a leakage gap between relatively moveable parts in a flow path between a region of high fluid pressure and a region of low fluid pressure comprises a sealing member having an upstream surface, a downstream surface, a radially outer surface and a radially inner surface, the sealing member being in communication with a housing via a resilient element. The resilient element is fixedly joined to the upstream surface of the sealing member such that during operation both the radial force induced on the sealing member by fluid flowing axially into and circumferentially over the radially inner surface and the axial force induced on the sealing member because of a pressure difference across the sealing member is resisted by the resilient element.

摘要： The present invention relates to a seal arrangement in which a substantially labyrinth type seal is utilised between a rotating component and a stationary component such as a housing. An edged fin of the seal arrangement incorporates a slot nozzle or a slot nozzle is associated with a fin in order that fluid flow through those slot nozzles either impinges upon opposed surfaces or at least narrows the available leakage gap width for greater sealing efficiency. Typically, several seal arrangements in accordance with the present invention and possibly in association with simple barrier fins are combined in an assembly to provide an appropriate acceptable combined operational sealing efficiency in a turbine engine.

摘要： This invention discloses an improved seal utilizing an optional air purge to assist in the elimination or removal of contaminants. The seal is most useful on spindles and utilizes a combination locking ring and diffuser ring to diffuse the air when utilized within the seal member itself. The pressurized air is passed from the diffuser into at least one cavity or chamber which is within the rotor of the seal and which, when the rotor is rotating it provides a centrifuging effect to efficiently and completely remove or eliminate contaminants, including the fluid, and thus preventing the contaminants from reaching the bearings which the seal or bearing isolator is protecting. The bearing isolator or seal element will operate efficiently with or without air pressure, but operates more effectively with requisite air pressure and volume applied to the diffuser and locking element.
