Abstract
574,128. Air filters. BRITISH FILTERS, Ltd., and ALLEN, R. G. Jan. 17, 1942, No. 723. [Class 8 (ii)] An air cleaner comprises a tubular member j receiving air to be cleaned and delivering the air, after mixing with particles of oil &c. to separating means such as a filter, the oil being supplied to the air through a series of pipes or ducts communicating with the interior of the tubular member at points of reduced pressure and depending at their other ends into an oil or reservoir. Fig. 2 shows apparatus in which dusty air enters at the annular base of a casing and rises in the'axial passage j, oil being drawn by Venturi action through tubes from an annular trough n. The air flows down an annulus in the outer part of the casing and up through a filter w of matted fibres or knitted wire to the'outlet. Oil containing the collected dust is deposited on the casing interior and in the filter and flows back to the trough through openings in its cover. A window y is provided. Fig. 3 shows apparatus in which air entering by ports 7 flows into a tubular port j perforated or formed of wire mesh. Part of the air strikes the cover 4, and part flows directly outwards through the perforations and the filter surrounding the tube. Oil is drawn into the air stream through tubes from an annular trough, and oil and dirt return to the trough through tubes 6 from the cover 4 and through openings in the lower filter cover 8. The filter and the cover 4 form a unit held in place by a spring 11 abutting on the removable cover 9 and by a supporting outer wall 13 of the oil trough.
