Abstract
Member elements as an alternative for blade wheels and blower rotors such as those used in axial-flow and radial-flow blowers. The member head has rotating, chain-like, mobile members which extend during operation due to centrifugal force and, upon standstill, collapse upon themselves due to gravity.
