Compact cyclonic separation device
First Claim
1. A cyclonic separation f device or a vacuum cleaner including a vacuum source, comprising:
- a cylindrical separation chamber having a central axis, an inlet at the upper portion, an outlet at the top and a closed bottom;
an inlet tube having an inlet opening and outlet opening positioned adjacent the separation chamber with an axis of the inlet tube substantially parallel to the central axis of the separation chamber;
a vortex vane positioned in the inlet tube causing inlet air to circulate;
a transfer region adjacent to the outlet opening of the inlet tube connected to the upper portion of the separation container for introduction of circulating air into the separation chamber;
a central outlet tube having an inlet in the separation chamber and an outlet communicating with the vacuum source; and
the separation chamber having a cylindrical sidewall with a disrupter ring located on the inside wall at a position below the inlet of the outlet tube.

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.
