  • Combination full flow and bypass filter with venturi nozzle
    Patent number: 5695637
    Abstract: A combined full flow and bypass oil filter for internal combustion engines includes a generally cylindrical filter body and a generally cylindrical filter head which is threadedly attached to the filter body. The filter head includes an inlet and an outlet and the flow path between the inlet and outlet extends through the filter body. Disposed within the filter body is a generally cylindrical and hollow full flow filtering element and a generally cylindrical and hollow bypass filtering element. The incoming flow of lubricating oil passes through the outer diameter surfaces of the full flow and bypass filtering elements and exits from these filtering elements through their hollow interiors. Concentrically positioned in the exiting flow path of the full flow filter is a Venturi nozzle which creates a low pressure zone.
