Abstract: A restricting device is positioned in the flow duct leading from the main inlet to the cleaning head of a vacuum cleaner and is movable between a restrictive position, in which it serves to restrict the cross-section of the discharge outlet, and an open position, in which it restricts the cross-section of the discharge outlet to a lesser extent. The restricting device is movable by the passage of debris along the flow duct.
Abstract translation: 限流装置位于从主入口通向真空吸尘器的清洁头的流动管道中，并且可在限制位置之间移动，限制位置用于限制排出口的横截面和打开位置， 其中它将放电出口的横截面限制在较小程度。 限制装置可以通过沿着流动管道的碎屑通过而移动。

Abstract: A cyclonic separation apparatus comprising at least two series connected separation stages and a receptacle for collecting material separated by the separation stages is described. The first stage comprises a first cyclone separator, and the second stage comprises a plurality of parallel connected second cyclone separators. The first and second separation stages are connected by at least one transfer duct which extends through the receptacle and transfers fluid that has been partly cleaned by the first separation stage to the second separation stage.

Abstract: A vacuum cleaner includes a pair of low efficiency cyclones connected upstream of respective groups of high efficiency cyclones by respective elongate ducts. The high efficiency cyclones of each group can be arranged in a line or a cluster extending away from their respective low efficiency cyclone, such that at least a portion of one side of the low efficiency cyclone is exposed. The high efficiency cyclones can be connected to their respective elongate ducts at respective positions along the length thereof, with each cyclone comprising an inlet connecting to the duct. The inlets of each high efficiency cyclone can be stepped along the axis of the duct with respect to the inlet of each other cyclone of the group, in a direction which extends across the width of the duct.

Abstract: A cyclonic separation apparatus comprises a plurality of series-connected separation stages 50,51, each comprising a plurality of cyclone separators 16/23 connected in parallel and disposed in a generally annular arrangement about a main vertical axis of the apparatus, with their respective longitudinal cyclone axes extending parallel to the main axis. The successive separation stages 50,51 in the direction of fluid flow are disposed radially inwardly of each other with respect to the main axis of the apparatus and are also vertically staggered upwardly, so that the outlet 20 of one separation stage 50 leads directly into the inlet 22 of the next downstream stage 51. The multi-stage, series connected cyclone separators of the apparatus provide a high separation efficiency, yet the annular arrangement of the stages 50,51 makes the apparatus compact and enables the apparatus to be utilized in a vacuum cleaner.
