A seal device has a seal main body. The seal main body includes a plurality of holes arranged to be recessed from a facing surface facing a rotor which rotates around an axis, and an ejection flow path which guides a fluid to bottom portions of the holes and ejects the fluid from the bottom portions.

A seal assembly includes a seal arc segment that has first and second seal supports. A carriage has first and second support members. The first support member supports the seal arc segment in a first ramped interface and the second support member supports the seal arc segment in a second ramped interface such that the seal arc segment is circumferentially moveable with respect to the carriage. First and second opposed springs bias the seal arc segment toward a circumferential default position.

A sealing device for a turbine engine bearing oil enclosure including a rotor shaft; an annular cover secured to an engine casing and arranged around the rotor shaft to co-operate therewith to define an oil enclosure that is to receive a bearing rotatably supporting the rotor shaft relative to the engine casing; a labyrinth seal mounted on the rotor shaft facing one end of the cover; an annular rim mounted inside the cover; a dynamic annular gasket interposed radially between the rim and the rotor shaft; and a clip for axially blocking the rim inside the cover and including at least one latch passing radially through the rim and being received radially inside a groove formed in the cover, is provided.

A sealing system for sealing a shaft located under water includes a bush mountable on the shaft and fixed to the shaft, a housing fixed with respect to the bush and surrounding a first portion of the bush, a lubricant chamber and an air chamber in the housing and open to the bush, the lubricant chamber being sealed with respect to the air chamber by a seal ring, a mechanical seal outside the housing and surrounding a second portion of the bush, an air supply line and an air discharge line connected to the air chamber, and a quantity of lubricating oil in the lubricant chamber, the lubricating oil being in fluid communication with a lubricant tank via at least one oil line, wherein an air pressure in the air chamber is greater than an oil pressure in the lubricant chamber.

Leakage of a working fluid from a shaft sealing device of a turbomachine which handles a liquid as the working liquid is reduced and also unstable fluid force which acts on a rotor is reduced. For this purpose, the turbomachine has a rotor having an impeller, a bearing which rotatably supports the rotor, a casing which contains the rotor therein and forms a stationary flow passage, and the shaft sealing device which reduces the leakage of the working fluid through a gap part between the casing and the rotor. The working fluid is a liquid. A plurality of axial grooves which are intermittently arranged in axial direction and circumferential direction of the rotor with a land part being interposed are provided in an inner circumferential surface of the shaft sealing device.

Disclosed are an air conditioning indoor unit and an air conditioner. The air conditioning indoor unit includes a housing and a ventilator in the housing. The housing has a frame and a panel. The panel defines a first ventilation opening, and the frame defines a second ventilation opening corresponding to the first ventilation opening. The ventilator is communicated with the second ventilation opening. The air conditioning indoor unit further includes a sealer disposed at the second ventilation opening and configured to seal a gap between the frame and the ventilator and/or to seal a gap between the frame and the panel.

A segment seal is configured to seal an annular clearance between a housing and a rotary shaft in a state in which a pair of seal rings are attached in an unrotatable state between one end portion of the housing and a support member attached to the housing so as to be opposite to the one end portion in an axial direction. The segment seal includes an anti-rotation member placed not to rotate relative to the housing or the support member, provided with a pair of raised portions fitted to the pair of seal rings to prevent rotation of the pair of seal rings, and configured such that at least one of the raised portions has a shape fittable only to either one of the seal rings.

A hydrostatic advanced low leakage seal configured to be disposed relatively rotatable components includes a base. The seal also includes a shoe extending circumferentially. The seal further includes a beam operatively coupling the shoe to the base, the beam having a beam length that is substantially equal to or greater than a circumferential pitch of the shoe.
