  • Apparatus for filtering impurities out of fluid
    Patent number: 6787033
    Abstract: Impurities contained in a fluid are removed by a filter having a housing containing a full flow filter, a bypass filter, and a conduit. The conduit includes a pressure reduction section. The full flow filter, bypass filter, and conduit are positioned such that the bypass filter is downstream of the full flow filter, and the pressure reduction section creates a pressure differential across the bypass filter that draws a predetermined portion of the fluid through the bypass filter. All of the fluid passes through the full flow filter. The predetermined portion of the fluid that passes through full flow filter is also filtered a second time by being drawn through the bypass filter.
