US Patent 8377160 Cyclonic dust collector with vee-shaped cyclone

A cyclonic dust collector arrangement employs a cyclone that has a conic body formed of a conic wall. An upper divider plate closes off the upper end of the conic body, with a vortex tube descending from a central passage in the divider plate. The conic body has a narrow nose at a lower end so that the upper divider plate and the lower nose define a cyclonic chamber within the conic body. The inlet conduit penetrates the conic wall below the divider plate. The fan chamber of the separator is mounted above the divider plate, and serves to induce air flow from the inlet conduit into the cyclonic chamber, and through said vortex tube into the fan chamber. The air is discharged through a final filter. This construction has reduced manufacture costs and improved dust separation.
