    Abstract: A cyclonic separation device (20) is provided having improved pressure loss characteristics. A fluid supply conduit (46) in flow communication with an inlet (32) to a cyclone (30) is located and configured to extend longitudinally through a central portion of the cyclone (30), whereby the sharp bending of the conduit may be reduced, thereby reducing pressure losses in the device, without unduly interfering with the cyclonic flow within the cyclone. The present invention may be adapted for use with cyclonic separation devices of all types, including single- and multi-stage cyclonic separators. The cyclonic separation device may be incorporated in a vacuum cleaner such as an upright vacuum cleaner. A three dimensional conduit which is optionally used with a cyclonic separator is provided.

    Abstract: A plate (10) supports a venturi (11) within a conduit (20) and divides the fluid flow stream into a first stream which flows through the venturi tube (11) and a second stream which bypasses the venturi tube (11). A variety of adjusting mechanisms are disclosed for varying the cross-sectional area of the bypass flow. The apparatus is adapted to allow the back pressure within the venturi tube (11) to force an increasing proportion of the flow stream to bypass the venturi tube (11) in order to maintain a relatively constant aspiration rate within the venturi tube. The adjustment mechanisms disclosed include a second plate (12), similar to the first plate (10), which is manually rotated and a blocking ring (60) which moves responsive to changes in rate of flow of the fluid flow stream. Helical passages (605) may also be provided at the outlet to promote mixing.

    Abstract: An apparatus and method for filtering a dirty air stream in a vacuum cleaner to obtain a clean air stream comprises subjecting the dirty air stream to a first cyclonic separation stage (32) to obtain a partially cleaned air sream and subjecting the partially cleaned air stream to an electronic filtration stage (50) and optionally a second cyclonic separation stage (60) to obtain the clean air stream. The electronic filtration stage (50) is optionally removable with a cyclonic cleaning stage from the vacuum cleaner. The electronic filtration stage (50) is optionally an electrostatic precipitator which utilizes air flow through the vacuum cleaner to generate the voltage used by the electrostatic precipitator.
