Abstract

The invention relates to a valve device comprising a valve housing (2) with a first and a second flow channel (3a, 3b), and a first and second damper shaft (8a, 8b), which are rotatable relative to the valve housing (2). A first damper (7a) is arranged in the first flow channel (3a) fixed to the first damper shaft (8a) and a second damper (7b) is arranged in the second flow channel (3b) fixed to the second damper shaft (8b). A rotatable regulating member (13) is arranged to control the rotational position of the damper shafts (8a, 8b) via two motion transfer members (20a, 20b), the respective motion transfer member (20a, 20b) being in engagement with a guiding (21) of the regulating member (13) so that the rotational position of the motion transfer member and thereby the rotational position of the associated damper shaft (8a, 8b) is controlled by the rotational position of the regulating member via this guiding (21).
