Abstract
A coupling is disclosed providing fluidic continuity between first and second orifices of two portions of an air circuit which includes a flexible sleeve, a first frame connected in fluid-tight manner to a first end of the flexible sleeve and having a first opening, and a second frame, connected in fluid-tight manner to a second end of the flexible sleeve and having a second opening. The coupling is deformable so that the flexible sleeve may adapt to the variable spacing between two avionics racks and is able to compensate for a misalignment between the orifices of two portions of an air circuit.

A coupling for connecting a first orifice of a first portion of an air circuit opening onto a first wall and a second orifice of a second portion of an air circuit opening onto a second wall, wherein the coupling comprises:
- a flexible sleeve,
- a first frame having a first face,
- the first frame having a second face connected in fluid-tight manner to a first end of the flexible sleeve and a first opening connecting the first and second faces,
- the first frame being configured to collaborate with a first coupling system having a first slide-way connection to allow the first frame to move with respect to the first wall in a first direction of introduction parallel to the first wall,
- a second frame having a first face,
- the second frame having a second face connected in fluid-tight manner to a second end of the flexible sleeve and a second opening connecting the first and second faces, the second frame being configured to collaborate with a second coupling system having a second slide-way connection to allow the second frame to move with respect to the second wall in a second direction of introduction parallel to the second wall.
An aircraft avionics rack coupling, comprising:
- a first frame;
- a second frame;
- a flexible sleeve having a first end and a second end;
- the first frame having a first face and a second face connected to the first end of the flexible sleeve, and a first opening connecting the first and second faces;
- the second frame having a first face and a second face connected to the second end of the flexible sleeve, and a second opening connecting the first and second faces;
- a first coupling system having a first slide-way connection allowing the first frame to move relative to a first wall of a first air circuit portion in a direction parallel to the first wall;
- and,
- a second coupling system having a second slide-way connection allowing the second frame to move relative to a second wall of a second air circuit portion in a direction parallel to the second wall.
