Abstract
A closure unit for a ventilation device having at least two pivotally arranged flaps for closing a respective ventilation channel. The two flaps can be moved by a common shaft which defines a pivot axis. The two flaps are thus positively coupled and can be actuated simultaneously by a single motor. The closure unit allows the use of two heat exchangers operated in parallel without an additional bypass channel.
