摘要： A centrifuge oil filter (52) for removing soot from oil in engines includes a centrifuge filter housing (54) and a replaceable centrifuge cartridge body (74). The top of the housing (54) includes a removable lid (60). The upper end of the body (74) is supported for rotation by a drive shaft (90), the upper end of the drive shaft (90) supporting a turbine (100). In the bottom of the housing is a centrifuge cartridge body lid (88) including a centrifuge hub (174), below the lid (88) is a housing bottom lid (62) including a set of bearings (94). The body (74) has a large surface area containment trap (114) which has several levels provided by concentric cylindrical walls and a plurality of partition walls in each level to provide for multiple compartment for soot agglomeration.

摘要： A filter assembly including a tubular filter housing and a removable filter element for use therein that employ a compressible seal element. The seal element connected to the rest of the filter element and located to sealingly engage the filter housing. In an aspect, a separate, rigid support member is disclosed that supports the seal element against the filter housing to improve the seal and prevent distortion of the compressible seal material. In another aspect, an end cap connecting the seal element to the rest of the filter housing includes an extending leg having improved features for retaining the seal element to the end cap. In another aspect, the seal element can be retentively received in a slotted member attached to the filter element.

摘要： A filter system using a filter cartridge adapted for disposal in an environmentally acceptable manner. The filter cartridge has no metal parts, and thus avoids the use of a metal center tube, or a center tube of any configuration. The housing itself carries a permanent center tube. A sealing arrangement formed between the filter cartridge and the housing provides a radial seal isolating the outer periphery of the filter cartridge from the remainder thereof. Filter and caps are in the lower pressure downstream zone, and thus any axial forces imposed on the filter place the filter media in tension to avoid the imposition of crushing loads on the unsupported filter.

摘要： A filter cartridge for use in a filter system, in which the cartridge has no structural metal or plastic parts and is adapted for environmentally acceptable disposal. A pleated paper filter media is formed into a cylinder, and potted end caps at the axial ends of the cylinder hold the shape of the filter. Sealing gaskets are associated with the end caps. At least one side has a radial seal formed at the outer periphery of the filter cartridge to protect the associated end cap from higher a pressure region found at the outer periphery. The other axial end can have a similar radial filter in some applications, or in other applications, where flow at that end of the filter is not desired, can utilize an axial seal specially configured to protect the associated end cap from higher pressure at the outer periphery. Maintenance of lower pressure at the respective end caps places any axial loads on the filter in tension, and thereby prevents the application of axial crushing loads on the filter cartridge.

摘要： A housing system for a removable filter cartridge in an automotive lubrication system. The housing is formed of a thin-walled sheet metal drawn cylinder, with end removed, to form an elongated cylinder with both ends open. A base end has a formed metallic base secured therein by a rolled flange in the sheet metal housing. A closure end has a formed threaded ring secured to the end thereof by another rolled and swaged connection between the sheet metal and formed ring. In the preferred embodiment, the base carries permanent center tubes, and the filter cartridge is of unsupported construction, containing no metallic supports, and adapted to be disposed of in an environmentally acceptable manner.
