Patent ID: 8118998

Claim:
A combination full flow media and bypass media filter cartridge for filtering fluid in an internal combustion engine, comprising: a venturi filter having a full flow media attached to and extending between a first endplate and a second endplate, the second endplate including an orifice; a stack of disks extending between a compression end and a venturi end, the stack of disks having a flow path defined by a plurality of openings wherein each disk includes at least one opening, the flow path extending between the compression end and the venturi end, the venturi end being substantially adjacent the second endplate of the venturi filter; and a compression mechanism connected to the venturi filter and applying a resilient biasing force on the stack of disks to bias the disks towards the venturi filter to maintain a minimum sealing force on the stack of disks, wherein the compression mechanism includes a longitudinal member and a resilient biasing member, the longitudinal member has a first end and a second end opposite to the first end and defines a fluid flow passageway, the fluid flow passageway is fluidly connected to the flow path of the disks, the resilient biasing member is connected to the longitudinal member at the first end, and the second endplate of the venturi filter is connected to the longitudinal member substantially adjacent the second end; and wherein the resilient biasing member extends from a first end portion to a second end portion, the first end portion is connected to the first end of the longitudinal member, and the second end portion abuts against the compression end of the disks.
