ABSTRACT:
A vapor filter cartridge for use in a volumetrically controlled crankcase ventilation system, which utilizes a cylindrical frame of expanded metal surrounded by a vapor filter cloth. The bottom end of the cylinder is sealed by a shallow cup type closure, having a central opening. The closure is attached and sealed and attached to the cylindrical wall by means of a thermosetting rubber-like material. A support flange is provided of molded thermosetting rubber-like material which is molded to the second end of the cylindrical frame. The flange serves as a structural member to support the cartridge. Also, because of its compliant nature, it serves as a sealing gasket between the support and cover structure of the ventilation device, and the top edge of a jar which is used to catch the liquid and larger particles which are carried into the jar from the crankcase space of the engine.
