Blocking reverse motion in cross-flow fan - involves use of pre-sprung blocking elements

The arrangement is for blocking reverse motion in a cross flow fan impeller separable from the drive. There are at least two displaceably mounted blocking elements (8) are arranged on a face side of the impeller. The blocking elements are prestressed by springs (15) in the blocking position, in whic...

More Information
Summary:The arrangement is for blocking reverse motion in a cross flow fan impeller separable from the drive. There are at least two displaceably mounted blocking elements (8) are arranged on a face side of the impeller. The blocking elements are prestressed by springs (15) in the blocking position, in which they block a rotation of the impeller against the drive direction. USE/ADVANTAGE - Cross-flow fan for cooling a vehicle in which the impeller, when separated from the drive, can only turn in one direction.
