Mischdüse für eine motorunabhängige Heizung

摘要

The mixing nozzle has a controllable circulated air inlet opening that allows air from the vol. to be heated into the mixing chamber (2), a controllable fresh air opening and an air outlet opening for air from the mixing chamber to the heating system. The inlet openings are controlled to set the mixing ratio of fresh and circulated air. The mixing chamber is a cylindrical tube (3) with axial openings (4,6) forming fresh air inlet and air outlet openings and at least one radial opening (7) forming the circulated air inlet opening. The control arrangement consists of a cylindrical sleeve (12) with radial openings (13) movable between open and closed positions for the radial opening(s).
