Abstract
A filter housing (14) has a first inlet (16) for receiving a first fluid such as oil from a machine such as an internal combustion engine (12), a first outlet (20) returning the first fluid to the machine, a second inlet (24) selectively receiving a second fluid from a source of cleaning fluid (28), and a second outlet (30) exhausting the second fluid. The filter housing has a first flow path therethrough from the first inlet through a filter element (40) in one direction to the first outlet, and a second flow path therethrough from the second inlet then through the filter element in the opposite direction then to the second outlet. The first and second inlets and the first and second outlets are all provided at the same axial end of the housing, for modularity. First and second common flow channels (58 and 68) in the housing each carry the first and second fluids in opposite directions. First and second valves (84 and 86) in the housing enable switching between filtration and cleaning modes.
