Abstract:
A filter includes a housing having a cavity. A media pack, which includes a filter media, is arranged within the cavity and includes a central opening extending between opposing ends of the media pack. A center tube is arranged within the central opening and extends out of the central opening beyond one of the ends to provide a first end. A relief valve is supported on the first end. The filter cartridge assembly is installed into the housing with the relief valve in sealing engagement with a tapping plate of the housing. The relief valve performs the function of a seal between the filter cartridge assembly and the tapping plate in addition to performing pressure relief functions.
Abstract:
A cooling system is provided that includes a cap secured to a degas bottle. A filter that includes a frangible area is arranged within the degas bottle near the cap to separate the degas bottle into first and second sides. The frangible area is breakable in response to a predetermined pressure differential to provide an opening in the filter and connect the first and second sides. The filter includes a housing that supports mesh which filters debris and prevents the debris from reaching a valve in the cap. The opening in the broken frangible area bypasses the mesh in the event the mesh becomes clogged with debris. In operation, the inventive filter provides a simple method of releasing pressure in the cooling system. A wall of the filter is fractured once the differential pressure reaches the predetermined differential pressure. The inexpensive filter can then be replaced.
Abstract:
An automotive fluid filter comprises a plurality of pellets that are sintered together and define a plurality of pores therebetween for passage of automotive fluid through the pores so as to filter the automotive fluid when the automotive fluid is advanced therethrough. An associated method is disclosed.
Abstract:
A method of manufacturing an oil filter module comprises directing a laser beam at a surface of an end cap but not at a rim of the end cap so as to fuse at least a portion of the end cap, spacing the end cap and the filter medium apart from one another during the directing step, inserting an end of the filter medium into the laser-fused portion so as to bond the end of the filter medium and the end cap together upon re-solidification of the laser-fused portion, and preventing flow of the laser-fused portion caused by the inserting step from reaching a peripheral diameter of the end cap by use of the rim.
