Abstract: Mounting plates used to mount filter elements within cylindrical canisters are made from sintered powdered materials, such as sintered powdered metal in order to reduce engineering and tooling lead time as well as to reduce costs. By making a mounting plate of sintered metal, the mounting plate can have a varying thickness which is an advantage not obtainable with a mounting plate stamped from steel sheet.

Abstract: A filter assembly includes a bowl assembly and a head member enclosing a filter cartridge. A filter center tube is permanently fixed to the bowl but allowed to rotate within a pocket in the bottom of the bowl. The top of the center tube is threaded for fastening to a stud on the filter mounting head. The center tube cannot be threaded onto the stud without the filter assembled over the center tube and into the bowl. In order to assemble the bowl to the head, the operator must turn the outside of the bowl. If a filter is not present, the bowl will turn independently of the center tube and no torque is transmitted to the threads. When the filter is properly installed, a series of tabs or features spaced around the inner perimeter of the wall of the bowl interlock with corresponding grooves or features in the outside diameter of the end cap of the filter. Tabs or features on the outer diameter of the center tube also interlock with grooves or features in the inside diameter of the end cap.

Abstract: A high pressure spin-on filter cartridge utilizes an end plate which is strengthened by four substantially triangular shaped gussets which project from an annular U-shaped bridge that supports an internally threaded hub member. The internally threaded hub member provides an outlet for the filter cartridge while a plurality of radially positioned inlet openings are positioned between the gussets. The gussets extend radially past a sealing gasket that seals the spin-on filter canister with a machine on which it is mounted.
