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 is fixed to the first damper shaft; a second damper shaft, which is rotatable relative to the valve housing; a second damper, which is arranged in the second flow channel and is fixed to the second damper shaft; and a regulating arrangement for regulating the rotational position of said damper shafts and thereby the rotational position of said dampers, which regulating arrangement comprises an actuator and a regulating member, which is rotatable relative to the valve housing and which is arranged to be rotated by the actuator, wherein the regulating arrangement further comprises: a first motion transfer member, which is rotatable relative to the regulating member and relative to the first damper shaft and is arranged to transfer a rotary motion of the regulating member into a rotary motion of the first damper shaft; a second motion transfer member, which is rotatable relative to the regulating member and relative to the second damper shaft and is arranged to transfer a rotary motion of the regulating member into a rotary motion of the second damper shaft, the respective motion transfer member being in engagement with a guiding of the regulating member so that the rotational position of the motion transfer member and thereby the rotational position of the associated damper shaft is controlled by the rotational position of the regulating member via this guiding, and said guiding comprises one or several guide tracks, the respective motion transfer member being provided with a protrusion received in the associated guide track of the regulating member.
