Abstract:
1. A valve device comprising: a valve housing with a first flow channel and a second flow channel; a first damper shaft, which is rotatable relative to the valve housing; a first damper, which is arranged in the first flow channel and which is fixed to the first damper shaft, this first damper being spring-loaded into an open position by means of a first spring member; a second damper shaft, which is rotatable relative to the valve housing; a second damper, which is arranged in the second flow channel and which is fixed to the second damper shaft; a regulating member, which is rotatable relative to the valve housing and which is arranged to act on said first and second damper shafts so as to achieve a rotation of either damper by rotation of one damper shaft at a time; and an actuator for rotating the regulating member, characterized in that the regulating member by means of a second spring member is spring-loaded into a rotational position in which the regulating member by acting on the first damper shaft is arranged to keep the first damper in a closed position, the second spring member being designed with a stronger spring force than the first spring member.
