ABSTRACT:
A rotor adapted for use in a hydrodynamic device comprising a cylindrical screen having a circumferentially continuous apertured zone. The rotor has an axis of rotation and includes a substantially cylindrical outer surface adjacent the cylindrical screen surface. The rotor further includes a plurality of sets of a plurality of adjacent vane members supported above a substantially cylindrical outer surface of a rotor by a plurality of brackets. The rotor has an axis of rotation and is mounted within and co-axial with the cylindrical screen to define an annular screening chamber between the rotor and the screen. The sets are equally spaced apart in a direction circumferential to the rotor axis, and the vane members extend the length of the screening chamber parallel to the rotor axis.
