SPIN-ON FILTER AND METHOD OF MANUFACTURING SAME

摘要

A spin-on filter including an improved baseplate preferably die cast from aluminum and an improved seaming lid preferably stamped from sheet steel. The baseplate includes a hub joined to a rim by ribs. The rim includes slots that receive tabs from the stamped seaming lid to provide for torque transfer between the canister and baseplate. The baseplate provides a seat for the seaming lid interfit with the baseplate to form a outer gasket groove. The baseplate provides the groove inner wall, while the seaming lid provides the groove outer wall and base. The inventive design in the baseplate and seaming lid provide for a groove for receiving an outer gasket and for torque transfer without complex or costly manufacture.
