摘要： A reinforcing assembly for air ducts includes a helical reinforcement with an outer circumference and at least one connecting element for fixing a pitch of a helix formed by the helical reinforcement. The at least one connecting element may be fixed to the helical reinforcement by a plurality of joints with mutually arranged spacing. The reinforcing assembly may be combined with an air duct to form a duct system for transmitting and distributing air that retains its shape regardless of the system's internal air pressure.

摘要： A duct for air transport comprises an inner jacket having an inlet end for connecting the duct to an air supply and an outlet end for connecting the duct to a duct for a further transport or distribution of air, and an outer jacket made of an impervious material and surrounding the inner jacket spaced therefrom. An insulating chamber is formed between the inner jacket and the outer jacket. The inner jacket and the outer jacket are adapted to conduct from the interior space of the inner jacket through the insulating chamber into the ambient atmosphere, namely in an amount of 0.02 to 100% of the total volume of air fed into the inner jacket. The area for conducting air into the insulating chamber and the area for conducting air away from the insulating chamber are spaced from each other during the operation of the duct.
