Abstract
A torsion damping mechanism for a rotary blower is provided that includes an input hub adapted to engage a first end of a torsion spring and an output hub adapted to engage a second end of the torsion spring. An intermediate hub is fixed for rotation with a first drive member. A bearing member includes an inner portion connected for rotation with the intermediate hub and an outer portion connected for rotation with the output hub. The bearing member may be a one-way bearing that permits torque to flow from the output hub into the intermediate hub and the first drive member when the output hub is driven in a first rotational direction, and permits the output hub to rotate relative to the intermediate hub with no substantial torque transfer therebetween when the output hub is driven in a second rotational direction.
