Abstract: An apparatus, system, and method for a quick-drain filter includes a filter housing, a clean fluid passage disposed axially in the housing, and a service drain passage disposed at an axial end of the housing and spaced radially away from the clean fluid passage. A protrusion extending radially from a stand pipe defining the clean fluid passage, disposed axially in the housing, defines the inner radius of the drain passage, and a housing member defines the outer radius. A plug extends axially from a filter cartridge to plug the drain passage when the cartridge is installed in the housing.

Abstract: A fluid filter housing for receipt of a fluid filter element and for threaded attachment to a mounting base includes a unitary, molded plastic shell, an annular, threaded nutplate, and a plastic weld ring. The plastic shell defines a hollow interior for receipt of the fluid filter element. The plastic shell also defines one side of an O-ring groove. The threaded nutplate includes a groove-side surface that defines a second side of the O-ring groove. The weld ring is securely joined to the threaded nutplate by co-molding and is securely joined to the shell by a spin weld process. The weld ring provides a third surface for the O-ring groove. As such, three separate components are used to create an inwardly opening three-sided annular groove for receipt of an annular seal for sealing an interface between the fluid filter housing and the mounting base.

Abstract: An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure and is adapted for securing to the machine. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the peripheral portion and central portion of the outer enclosure. Oil may pass through the pressure-actuated valve only when an oil pressure differential between the peripheral portion and the central portion of the outer enclosure exceeds a predetermined threshold pressure. A secondary filter has a second porosity greater than the first porosity, and is fixed fluidly between the pressure-actuated valve and the central portion of the outer enclosure.

Abstract: The invention concerns a filter insert (1) that is provided as an exchangeable insert in a filter, in particular an oil filter, fuel filter or the like of an internal combustion engine. The filter comprises a filter housing (3) that can be separated along a separating plane (2) and the exchangeable filter insert (1) extending in an axial direction (18). Two housing parts (4, 5) of the filter housing (3) are sealed relative to one another along the separating plane (2) by means of a seal (6). The seal (6) is secured slidably and captively in the axial direction (18) on the filter insert (1).

Abstract: A filter assembly including first and second mating parts and a seal received in a groove of the first mating part. The seal includes a main body and a resiliently flexible, sloping skirt that extends from one side of the main body to a distal end spaced from the main body. The seal is sized so that the resiliently flexible skirt normally extends out of the groove of the first mating part when the skirt is not biased towards the main body. When the first mating part is slid against the second mating part, the second mating part causes the distal end of skirt of the seal to be biased into the groove and towards the main body of the seal.
