A FULL-FLOW MICROFILTRATION DEVICE AND METHOD FOR FILTERING FLUIDS

摘要

A full-flow microfiltration device ( 12 ) and method for filtering fluid in a hydraulic system ( 10 ) is provided. The filtration device ( 12 ) includes a housing ( 22 ) and a filter medium ( 24 ) sealingly coupled to and contained within the housing ( 22 ). The housing ( 22 ) and the filter medium ( 24 ) define a central chamber ( 26 ) and a concentric chamber ( 28 ). The central chamber ( 26 ) directly communicates with an entry port ( 34 ) and an exit port ( 36 ) formed within the housing ( 22 ) for directing a first flow through the filter device ( 12 ). The concentric chamber ( 28 ) directly communicates with an inlet port ( 38 ) and an outlet port ( 40 ) formed within the housing ( 22 ) for directing a second flow through the filter device ( 12 ). A portion of the second flow is drawn from the concentric chamber ( 28 ) through the filter medium ( 24 ) into the central chamber ( 26 ) and into the first flow.
