Abstract: An adjustable orifice for use in an aircraft air conditioning system includes a first orifice element which has an orifice frame as well as a first orifice area. When the orifice is assembled at a duct, the first orifice area of the first orifice element leaves open a part of a cross section of the duct. The orifice also includes a second orifice element with a second orifice area. When the orifice is assembled at the duct, the second orifice area of the second orifice element leaves open a part of the cross section of the duct. The second orifice element is rotatable about an axis, so that the second orifice area is rotatable relative to the first orifice area in order to set a desired flow cross section in the duct.

Abstract: A shower drainage outlet for a shower tub in an aircraft is stated, which shower drainage outlet comprises three parts that can be displaced, angled or rotated in relation to one another. In this way horizontal, vertical and angular tolerances can be compensated for. Furthermore, the shower drainage outlet is designed to be inserted through an opening in the floor region of the aircraft.

Abstract: An adapter for coupling connecting pipes for a commercial aircraft comprises an adapter top and an adapter bottom. The adapter bottom has a first adapter pipe that can be positioned within a recess in a floor of the aircraft. An attachment flange is formed to the external circumference of the first adapter pipe, through whose central flange opening the first adapter pipe is led, which attachment flange is positioned on the first adapter pipe end of the first adapter pipe and is attached by one flange side to a bottom floor region of the floor. The adapter top has a second adapter pipe to which a tubular supporting flange is joined. The pipe end region reinforced with said supporting flange of the second adapter pipe is inserted into the pipe cross section of the first adapter pipe.

Abstract: An adjustable orifice (10) for use in an air conditioning system, in particular an aircraft air conditioning system, comprises a first orifice element (18) which has an orifice frame (20) as well as a first orifice area (22), wherein when the orifice (10) is assembled at a duct (12) of the air conditioning system the first orifice area (22) of the first orifice element (18) leaves open a part of a cross section of the duct (12) The orifice (10) also comprises a second orifice element (32) with a second orifice area (34), wherein when the orifice (10) is assembled at the duct (12) the second is orifice area (34) of the second orifice element (32) leaves open a part of the cross section of the duct (12).

Abstract: An adapter for coupling connecting pipes for a commercial aircraft is suitable for efficient installation in the floor. Furthermore, said adapter will be able to implement leakage-free connecting of pipes of a system for liquids. The adapter comprises an adapter top and an adapter bottom which may be implemented with a tubular adapter body. The latter is intended for connection to a connecting pipe through which a flow-through medium containing sewage and/or other liquids is conveyed. The adapter bottom may comprise a first adapter pipe that can be positioned within a recess in the floor. An attachment flange may be formed to the external circumference of the first adapter pipe, through whose central flange opening the first adapter pipe is led, which attachment flange is positioned on the first adapter pipe end of the first adapter pipe and is attached by one flange side to a bottom floor region of the floor. The adapter top may have a second adapter pipe to which a tubular supporting flange may be joined.

Abstract: An adapter that is used for connecting pipelines of a system for liquids installed internally in an aircraft and for floor-bridging installation in an aircraft is improved to such an extent that the adapter arrangement is carried out with less labour and fewer difficulties being experienced in the installation. Preinstallation of the adapter on floor panels implement leakage-free (non-dripping and pressure-proof) connecting pipes The connecting pipes are integrated in an aircraft's internal system for liquids and are separately laid out in the interior of the aircraft, above and/or below a floor. The adapter comprises an adapter top and an adapter bottom, which are both implemented with a pipe-shaped adapter body. The latter is intended for connection to the aircraft's internal system for liquids, such as potable water or waste water. The adapter bottom comprises a first pipe that can be positioned within a recess in the floor.
