  • Method of assembling an improved bead-lock high-pressure filter utilizing a stamped metal cover, and filter obtained thereby
    Patent number: 6615989
    Abstract: An improved, spin-on, bead-lock filter which is particularly adapted for use in a high-pressure oil filter in a diesel engine is provided. The filter includes a housing containing a filter medium and having an inwardly deformed periphery, and a cover assembly including a cover plate and a retainer plate having mutually spaced apart outer edges for forming a recess that receives the inwardly deformed portion of the housing. A gasket whose outer diameter is less than the inner diameter of the undeformed housing is seated in the recess. The smaller outer diameter of the gasket relative to the inner diameter of the housing allows the cover assembly to be easily positioned in place over the top of the housing during manufacture. Both a mechanical connection and a seal is formed between the cover assembly and the housing when the periphery of the housing is inwardly deformed pursuant to a bead rolling step in conformance with the assembly method of the invention.
