    Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid. Additional aspects include exchangeable filter cartridges or filter elements in single and multi-round configurations, embodiments with aspiration tubes and dip tubes and still others with hydrophilic/hydrophobic recovery filters that function as filters and as valves for the recovery port.

    Abstract: A fuel injector filter is disclosed. The filter may include an inner ring concentrically surrounded by an outer ring. The inner ring may radially extend between an inner ring inner perimeter and an inner ring outer perimeter, and comprise a first port radially extending between the inner ring inner perimeter and the inner ring outer perimeter. The outer ring may radially extend between an outer ring inner perimeter and an outer ring outer perimeter, and comprise a first aperture radially extending between the outer ring inner perimeter and the outer ring inner perimeter. The first aperture may be circumferentially offset from the first port. A filtration channel may radially extend between the inner ring outer perimeter and the outer ring inner perimeter and be configured to impede movement of a particle toward the first port.
