Device for connecting two duct elements and a baffle in an aircraft air conditioning system
View Patent ↗A device ( 10 ) for connecting two duct elements ( 12, 14 ) and a baffle ( 34 ) in an aircraft air conditioning system may include first ( 30 ) and second ( 32 ) connecting flanges each connected to one of the two duct elements ( 12, 14 ), and at least one connecting element ( 38 ) formed on the first connecting flange ( 30 ) which interacts with at least one corresponding connecting element ( 40 ) formed on the second connecting flange ( 32 ) to establish the connection of the two duct elements ( 12, 14 ) and the baffle ( 34 ). The first ( 30 ) and/or second connecting flange ( 32 ) has/have an opening ( 44 ) for receiving the baffle ( 34 ), which is substantially disc-shaped and formed with at least one air passage ( 46, 48 ). The baffle ( 34 ) serves to control the flow of at least one air stream flowing through the connected duct elements ( 12, 14 ).
1. A device configured to connect two duct elements and a baffle in an aircraft air conditioning system, the device comprising:
the baffle, wherein the baffle is formed to control the flow of at least one air stream flowing through the connection,
a first connecting flange configured to be connected to a first of the two duct elements to be connected, and
a second connecting flange configured to be connected to a second of the two second duct elements,
wherein at least a first connecting means is formed on the first connecting flange, which first connecting means interacts with at least a second connecting means formed on the second connecting flange to establish a connection of the two duct elements and the baffle,
wherein the baffle is substantially disc-shaped and formed with at least one air passage, wherein at least one of the first and the second connecting flange has an opening for receiving the baffle,
and wherein the second connecting means comprises at least one fastening strap.
2. The device according to claim 1 , further comprising a seal which is disposed between the first and second connecting flanges.
3. The device according to claim 2 , wherein the seal is made of a resiliently elastic material.
4. The device according to claim 1 , wherein the first and second connecting flanges axially overlap at least partly in an overlap area.
5. The device according to claim 4 , wherein a seal is disposed in the overlap area between inner and outer circumferential surfaces of the first and second connecting flanges.
6. The device according to claim 1 , wherein the first connecting means comprises at least two pins which are disposed on the first connecting flange and lie substantially opposite one another.
7. The device according to claim 1 , wherein the second connecting means has at least one opening for receiving the first connecting means.
8. The device according to claim 1 , wherein the second connecting means is formed so as to be resiliently deformable.
9. The device according to claim 1 , wherein the baffle has a terminal edge which has a cross-sectional profile which is formed to engage in a sealing manner with a mating profile which corresponds in cross section and is formed in the area of the opening of the at least one of the first and second connecting flame.
10. The device according to claim 9 , wherein the terminal edge of the baffle has a fastening means with a locking element which engages in a corresponding recess which is applied in the area of the opening receiving the baffle.
11. The device according to claim 10 , wherein the fastening means is formed so as to be at least partly resiliently deformable.
