ABSTRACT:
This invention discloses a device usable as a pump or a compressor or a flow meter that includes a plurality of flaps having a substantially "comma-shaped" cross section assembled in a parallel arrangement wherein the flaps are respectively pivotable about a plurality of pivoting axes axisymmetrically positioned about the central axis of the assembly of the flaps. The outer boundary of the cross section of the assembly of the flaps takes a substantially circular configuration when all of the flaps are pivoted to the fully retracted position. The assembly of the flaps is rotatably disposed eccentrically within a cylindrical cavity having a cross section of a circle or ellipse or other configuration of smooth perimeter which cylindrical cavity includes a fluid inlet and outlet disposed at two substantially diametrically opposite positions across a plane including the central axis of the assembly of the flaps and the central axis of the cylindrical cavity.
