A turbomachine casing () comprising an endoscopy port () and a member () mounted on and fixed to the casing and comprising a duct () that communicates with the port and that comprises an internal thread into which a cap () can be screwed, and means () for fixing the member to the casing, characterised in that it further comprises a cover () mounted on the member and at least partially covering the fixing means in order to hinder, or indeed prevent, access to same when the cover is mounted on the member, the cover being arranged to allow free access to the duct when the cap is not screwed into the duct.

A turbomachine bearing housing comprising a fixed wall, a rotating shaft, first and second seals between the wall and the shaft, and a chamber between the fixed wall and a stator element supplied with air via an opening close to the shaft. An air guide is arranged along the surface of the wall of the housing, outside same, such that at least a portion of the air exiting the guide passes between the first seal and the shaft, the air guide being supplied with air by an air intake separated radially from the shaft, the air from the air intake being at a higher pressure than at the shaft.

Turbomachine bearing housing

A turbomachine element includes a stator, a rotor, and a first sealing means for sealing between the rotor and the stator. The element is arranged to be active when the rotor is in the operating position of same around the axis of rotation thereof. The element includes an auxiliary pressure sealing means, sealing between the rotor and the stator and is arranged so that the two sealing means are active when the rotor is placed along the axis of rotation thereof during an assembly operation in a test position. In the test position, the rotor and the stator form an enclosure between said two sealing means.

An extraction sleeve for extracting two rotationally symmetrical parts that are joined together by interference fit, the extraction sleeve including: a head having a conical part; a cylindrical body, the internal part of the cylindrical body having a screw thread suitable for the screwing of an extraction screw; the conical part of the head of the extraction sleeve forming a friction component suitable for coming into contact with one of the rotationally symmetrical parts, the friction component being designed so as to determine a limit slipping torque greater than the friction torque generated at the screw thread of the sleeve by screwing of the extraction screw.

Extraction sleeve

A device for suspending a turbojet casing, the device including a shouldered pin extending through aligned orifices of two lugs of a clevis secured to the casing. A protection piece for providing protection against wear is mounted on each lug of the clevis and has the shouldered pin passing therethrough, the protection piece being prevented from moving in rotation on the lug by co-operating shapes.
