Abstract: A cyclonic separation device for a vacuum cleaner including a cylindrical separation container, an inlet tube parallel to the axis of the chamber having a vortex vane disposed axially in the inlet tube. Air rotates in one direction in the inlet tube, and preferably in the opposite direction in the separation chamber tube. The separation chamber includes a cylindrical sidewall with an upper central outlet tube and a closed bottom for collecting separated dirt. A disrupter ring located on the inside wall of the middle portion of the separation chamber includes a curved surface and sharp edge for lifting air flow off the chamber wall. A outlet tube disc spaced from the inlet of the outlet tube is located in the chamber below the disrupter ring.

Abstract: A cyclonic separation device for a vacuum cleaner including a cylindrical housing, an inlet tube parallel to the axis of the housing having a vortex vane disposed axially in the inlet tube. Air rotates in one direction in the inlet tube, and preferably in the opposite direction in the housing. The housing includes a cylindrical sidewall with an upper central outlet tube and a closed bottom for collecting separated dirt. A disrupter ring located on the inside wall of the middle portion of the housing includes a curved surface and sharp edge for lifting air flow off the housing wall. An outlet tube disc spaced from the inlet of the outlet tube is located in the housing below the disrupter ring.
