    摘要: A reusable oil filter adapted to filter oil used in an engine includes a housing operatively connected to the engine, filter media disposed within the housing, a singular backwashing inlet operatively connected on the housing and an oil drain operatively connected with the housing. Pressurized air delivered through the backwashing inlet forces filtered oil to backflow through the filter media displacing contaminated oil from the filter media and creates an air-oil foam for further cleaning the filter media while the housing remains connected to the engine.

    摘要: A filter (102) for filtering fluid from a machine (104) includes a filter housing (106, 250) having a first inlet (114) receiving a first fluid from the machine, a first outlet (116) returning the first fluid to the machine, a second inlet (118) selectively receiving a second fluid from a source (120) of cleaning fluid, and a second outlet (122) for exhausting the second fluid and for exhausting the first fluid from the dirty side of the main filter element (124) in the housing backwashed by the second fluid. The filter housing has a first flow path (126) therethrough from the first inlet then through the filter element in one direction then to the first outlet, and has a second flow path from the second inlet then through the filter element in the opposite direction then to the second outlet, the first and second flow paths having common but opposite direction portions through the filter element. A second filter element (156) is provided in the second flow path.
