Abstract:
A combination full flow media and bypass media filter cartridge for filtering fluid in an internal combustion engine. The apparatus includes a venturi filter having a full flow media attached to and extending between a first endplate and a second endplate. The second endplate includes an orifice. The apparatus further includes a stack of disks extending between a compression end and a venturi end. The stack of disks has a flow path defined by a plurality of openings wherein each disk includes at least one opening. The flow path extends between the compression end and the venturi end. The venturi end is substantially adjacent the second endplate of the venturi filter. The apparatus further comprises resilient compression member connected to the venturi filter for maintaining a minimum sealing force on the stack of disks.
