The device has a flap body (3) supported in a housing (1), and another flap body (4) fixed directly or indirectly at a shaft (6). The latter flap body is supported parallel to another shaft (5) in the housing. The shafts are swivelable together via an actuator. The latter flap body is fixed eccentrically directly or indirectly at the former shaft. The flap bodies extend from the shafts in a closed condition in a common level at opposite directions, where rotation of the shafts takes place synchronously in same direction via the actuator. Toothed wheels are arranged on ends of the shafts. |
