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) that is 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 regulating member (11a) is arranged to act on said first and second damper shafts (8a, 8b) so as to achieve a rotation of either damper (7a, 7b) by rotation of one damper shaft at a time.
