Abstract

The means has a channel system (40) with variable openings in relation to the ventilated rooms and an air transport means (30), preferably a blower. In the channel system, preferably adjacent to the blower, a throttle flap (33, 46) is arranged in such a manner that its axis of rotation is arranged at the flap edge or outside an opening (36) of the ventilation channel (40), which opening is influenced by the throttle flap. The throttle flap (33, 46) is arranged in such a manner, possibly with the aid of a weight (35) on an arm (39), that the centre of gravity (37) of the throttle flap lies at least approximately on the plane of the axis of rotation (34) when the throttle flap is in the closed position. These means bring about a greater pressure reduction over the throttle flap with small flows than with large flows. As a result, a blower curve is produced, which rises from small to large volume flows. <IMAGE>
