The present invention relates to a filter for liquids. More particularly it is concerned with providing a clog-resistant filter of the kind in which a filter element (usually of hollow cylindrical shape), having at least one 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.
