Abstract
A device to separate particles from a gas stream. The device may be a vacuum cleaner (10) or an industrial dust extraction device. The vacuum cleaner (10) includes a rotor assembly (20) to which the gas stream is delivered, the rotor assembly (20) having a plurality of gates (42) that collect dust and open to deliver dust to an outlet chamber (23). The gates (42) include Cone or more gates (42) that may include a resilient deflectable flange that is movable between an open and a closed position to provide for passage of the dust to the chamber (23).

1-10. (canceled)
A device to separate particles from a gas stream, the device including:
- a chamber having an inlet and an outlet between which the gas stream flows;
- a rotor mounted in the chamber for rotation about a rotation axis, the rotor including a longitudinal passage extending through the rotor along which the gas stream passes in moving from the inlet to the outlet of the chamber;
- a plurality of gates located radially outward of the passage which collect the particles from the gas stream passing through the passage, each of the gates being operable to move between a closed position for collecting the particles at the gate, and an open position providing for delivery of the collected particles from the gate;
- and
- a cavity into which the particles are delivered from the plurality of gates.
