Double control mechanism for climate control flaps in vehicles

摘要

The two valve flaps (1 and 2) of the climate control system of a vehicle are controlled by separate device. The primary control (3) operates on both the primary valve (1) and the secondary valve (2). The second control (4) operates on the second valve (2).The pull knob (3) operates to control the angular position of both valves, which pivot around the central axis. The rotary knob (4) operates by means of a stopped bearing (13), which is mounted on the drive plate (12), and by means of the toothed sector plate (10) and screw drive (11), to control the angular position of the second valve (2).
