Abstract
The present invention provides a liquid filtering apparatus wherein solids suspended in the liquid are accummlated to form a cake on the filter media as the liquid passes through the media. Upon the buildup of such solids, pressurization upon the liquid forces remaining liquid through the media. Such pressurization is inactivated upon excessive cake buildup, and a conduit helically wound about the outside of the filter media is expanded by air pressure. The conduit is attached at various points about its length so that it forms chord lines between such connection points. Such expansion and chording of the conduit breaks the cake from the media.
