Ceiling or wall air outlet with air feed pipe - which has internal nozzle tube, forming annular gap and radial air distributor with collar-like adjusting ring

摘要

The air feed pipe(1) contains a nozzle tube (2), forming an annular gap (S). The nozzle tube has a radial air distributor (3) and a central nozzle (4). The pipe and tube are connected air-tightly at the intake end (5) of the nozzle tube. The latter also contains an adjusting ring (6), which is axially adjustable until it completely covers the air distributor. The air distributor is formed as a nozzle tube section, with radial air outlets (7), e.g. perforations, or a sieve-like structure. The ring is adjusted by a rod, which is guided axially and centrally in the nozzle tube. USE/ADVANTAGE - For air conditioning systems,with variable depth of feed air in a simple and effective design.
