Patent attributes
A connection piece for the articulate connection of a first and a second tube, in particular a first and a second tube of a hot air supply system fed from the power unit of an aircraft, with the possibility of compensating for tolerances, wherein an interval between a tube end of the first tube and a tube end of the second tube is enclosed by a sealing mechanism. The tube ends each have a support ring, wherein the support rings are connected to each other by at least two connection elements arranged outside the sealing mechanism. At least two metal bellows are preferably used as the sealing mechanism, which enable almost maintenance-free operation. Steel ropes are preferably used as connection elements. In particular, tubes with a diameter of up to 160 mm, which are intended, depending on the material used, to conduct media with temperatures of up to 8500 C and pressures of up to 20 bars, can be connected in an articulate manner to each other by means of the connection piece.
