  • Spin-on filter cartridge which can be easily disassembled to allow the replacement of a filter unit included therein
    Patent number: 11471801
    Abstract: A spin-on filter cartridge includes a flange with peripheral holes for entrance, and a middle hole for exit. The cartridge includes a container with a cylindrical side wall having a base at a first end, and an opening at a second end. The flange reversibly occludes the opening. The container reversibly connects to the flange by a bayonet. The cartridge includes a filter unit including a cylindrical side wall having a base at a first end, and an opening at a second end. The bases oppose each other, the filter unit opening opposing the flange. The filter unit rotates integrally with the container. A spring between the bases pushes the filter unit towards the flange, the filter unit dividing the space into a first compartment, outside the filter unit, accessible by peripheral holes of the flange, and a second compartment, inside the filter unit, accessible by the middle hole.
