ABSTRACT:
A liquid filter assembly is provided including a roll filter disposed within a casing. A contaminated liquid is supplied to a space adjacent to one end face of the roll filter for passage therethrough. A filter member formed of a material such as non-woven fabric covers the end face of the roll filter where the liquid is supplied, and the filter member is in turn covered by a filter retaining disc so that the filter member is normally urged against the roll filter. The retaining disc is formed with a number of openings to pass the liquid therethrough, thus preventing the liquid pressure from being directly applied to the roll filter.
