  • Patent number: 12447669
    Abstract: A fluid conduit for aircraft, the conduit having a pipe made from thermoplastic material having a connection end which extends along a pipe axis and a connector which is intended to be mounted in the connection end by a translational movement along the pipe axis in a downstream direction, the connector having a joining portion which extends longitudinally along the connector axis and which is configured to extend into the connection end, the joining portion having a free longitudinal end which is chamfered, the free longitudinal end being configured to be radially deformed after the connector is mounted in the connection end, which has been thermally expanded beforehand, so that the conduit has an internal surface which has an internal radius which is substantially constant at the interface between the connector and the pipe.

  • Publication number: 20240280198
    Abstract: A fluid circuit, in particular for an aircraft, comprising at least one first duct (1) and a first connecting member (5), at least one second duct (2) and a second connecting member (6), a connector piece (3), for joining the two connection ends of the ducts (1, 2) in a leaktight manner, comprising a central sleeve (4) configured to cooperate, at a first end, with the first connecting member (5) and, at a second end, with the second connecting member (6), the central sleeve (4) having a plurality of flexible teeth (41) in order to correct any error in alignment between the first axis (X1) and the second axis (X2).
