摘要： A restricting device (800) is positioned in the flow duct (893) leading from the main inlet (111) to the cleaning head (100) 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 (800) is movable by the passage of debris along the flow duct (893).
摘要翻译：限制装置（800）位于从主入口（111）引导到真空吸尘器的清洁头（100）的流动管道（893）中，并且可在限制位置之间移动，限制装置用于限制十字排出口的截面以及打开位置，其中排放出口的横截面在较小程度上限制。限制装置（800）可通过沿着流动管道（893）的碎片通过而移动。

摘要： A vacuum cleaner comprises a cyclone separator having a cyclone chamber (15) for separating matter contained in the airflow, An inlet duct (14) for the flow of fluid (5) extends tangentially into the upper end of the cyclone through the sidewall 10 thereof. The upper end of the cyclone chamber (15) is closed by an upper end wall (11) and a tubular outlet duct or so-called vortex finder (12) extends into the cyclone chamber (15) from the upper end wall (11). A cross member (13) extends across the upstream end of the vortex finder (12) between circumferentially-spaced wall portions 10 thereof. The cross member (13) mechanically stiffens the vortex finder (12) and helps to reduce noise-generating vibrations. The cross member also serves to disrupt the airflow at the inlet to the vortex finder, (12) thereby preventing any airflows which may induce resonance.
