ABSTRACT:
A liquid filter includes a filtering medium of a collapsed cylindrical form which defines cooperating accordian pleats that form contaminant collecting walls. The medium is self-supporting, and divides the filter into inlet and outlet chambers across the medium. When the restriction of the medium increases, thereby increasing the pressure differential across the medium, the accordian pleats collapse until corrugations on the pleats engage with one another, thereby resisting further collapse of the medium. As the pressure differential increases still further to the extent that the corrugations are collapsed, a part of each fold is kept apart by adjacent double thickness portion of the fold or pleat, so that a minimum flow of liquid through the filter is maintained.
