Air control device for heating, air-conditioning or ventilation systems in road vehicles - has air guide channel in which is pivotable air valve for controlling air throughput cross-section

摘要

The positioning bar (20) is connected via a second ball link (22) with a pivot lever (23) positioning the air valve (13) in the air flow direction. The pivot axis (24) of the pivot lever at right-angles to and at a distance from the air valve pivot axis (12) runs at an acute angle to the channel axis (11). The pivot lever is coupled to the positioning component (30). ADVANTAGE - The device is very compact, opposes no or very little additional flow resistance to the air flow in all air valve positions, and obviates air noise.
