Patent number: 5076942Abstract: The present invention relates to a method for filtering liquids. More particularly it is concerned with providing a clog-resistant filter of the kind in which a open end and with walls of metal, plastic or other suitable material bearing numerous perforations, is placed within a housing in such a manner that the liquid entering the housing must flow from the inside of the filter element out through the perforations in the latter, before it can leave the housing, with the result that solid material strained from the liquid flowing through the filter is retained within the filter element.Type: GrantFiled: October 29, 1990Date of Patent: December 31, 1991Assignee: Amiad U.S.A., Inc.Inventors: Geoffrey Goodman, Uri Cagan, Yitzhak Orlans

Patent number: 4710284Abstract: A cyclonic separator for separating solid particles from a fluid comprises a housing including a chamber, a first deflector between the chamber and its inlet for deflecting the fluid flowing from the inlet to a radially-extending passageway before reaching the chamber, and a second deflector between the radially-extending passageway and the chamber for deflecting the fluid in the circumferential direction before entering the chamber to produce a vortex therein for separation of solid particles from the fluid before the fluid reaches the chamber outlet. The housing further includes a dirt-purging outlet at the bottom of the chamber for purging the solid particles settling therein.Type: GrantFiled: October 25, 1985Date of Patent: December 1, 1987Assignee: AmiadInventor: Meir Amit
