ABSTRACT:
A self-cleaning pressure filter system including a housing having an unfiltered liquid inlet and a filtered liquid outlet, a filter element of substantially constant cross section having an interior communicating with the unfiltered liquid inlet and an exterior communicating with the filtered liquid outlet for filtering solids from the liquid and wherein filtered out solids are left in the interior of the filter element. A cleaning unit is moved axially along the interior of the filter element and carries at least one radially expansible, substantially annular cleaning member movable in an axial path along the interior face of the filter element for removing solids accumulated thereon. In an least one embodiment of the invention, the radially expansible cleaning member is a split ring circumferentially exhaustible by a spring member. In at least one embodiment of the invention, axial reciprocation of the cleaning member is achieved without need to reverse a rotating member.
