AIR DISTRIBUTOR Russian patent published in 2005 - IPC

FIELD: air ventilation systems, possibly in rooms.

SUBSTANCE: air distributor includes housing with outlet openings. Said housing is secured to air duct by means of cylindrical inlet branch pipe with ejection windows in its surface. Converging insert is mounted in inlet branch pipe. Housing is diverging one and it is provided with perforated damper mounted in housing in parallel relative to its bottom with possibility of axial rotation. Discharge openings are formed in bottom of housing. The last discharge opening and perforated damper are in the form of spherical segments whose convex portions are turned to inlet branch pipe. Cylindrical inlet branch pipe has two formed in press spherical grooves arranged in parallel relative to bases of cylindrical inlet branch pipe (one groove is arranged over and other groove is arranged under ejection windows). Inlet branch pipe itself is embraced by cylindrical collar spaced by minimum gap from its surface. Said collar has openings identical to ejection windows and arranged at the same level. Cylindrical collar also has formed in press spherical grooves having diameter slightly less than diameter of grooves of inlet branch pipe and arranged at the same level. Such structure provides rotation of cylindrical collar around inlet branch pipe on its surface. Cylindrical collar is provided in addition with gear wheel secured to its surface and engaged with pinion of actuating mechanism. The last is electrically connected to air temperature controller and air temperature pickup. Perforated damper mounted at minimum gap relative to bottom of housing has shaft secured to it, passing with gap through bottom of housing and having in its lower end thread engaging with pinion of other actuating mechanism. The last is electrically connected with air stream speed regulator and pickup of said parameter.

EFFECT: possibility for automatic control of temperature and speed of inlet air streams.
