Drive for closure device of air inlet of e.g. radiator for diesel engine of motor car, has cable wound around pulleys such that closure device is brought into closed position or opened position based on rotational direction of drive roller

摘要

The drive (11) has a motor (13) driving a fan wheel (12) and arranged at a rotational axis (121) of the fan wheel. The motor is held by a frame at which a cable system is provided. The cable system is actuated by a drive roller (5) rotating around the rotational axis. A cable (61) driven by the drive roller is wound around pulleys (71-74) supported on the frame such that a closure device of an air inlet (2) is brought into a closed position or an opened position based on a rotational direction of the drive roller.
