摘要： A filter arrangement includes a filter cartridge having a first filter element and a second filter element. The first filter element includes a first tubular section of filter media extending between first and second end caps and defining a first open filter interior. The second filter element includes a second tubular section of filter media operably oriented in the first open filter interior. The second tubular section of filter media extends between third and fourth end caps and defines a second open filter interior. The first end cap defines an inner container and an outer container circumscribing the inner container. The outer container is secured to the first tubular section of filter media. The inner container has an end wall axially spaced from the outer container. The third end cap has a media end secured to the second tubular section of filter media and a tubular wall axially extending from the media end. The tubular wall is circumscribed by the inner container of the first end cap. The filter arrangement further includes a housing for the cartridge, and can be either a spin-on or a bowl-cartridge filter. The filter arrangement is usable in a hydraulic system including a sump; an implement valve; a pump; and a filter head in fluid communication with the sump, implement valve, pump, and filter arrangement.

摘要： The present invention relates to a device having two or more separate filtration layers that can be independently tested for integrity yet which allow for serial filtration through the two or more layers to obtain the desired characteristics such as retention. The device is made of two or more filtration areas, each containing one filter layer. Each area has one filtration layer and a first endcap bonded to a first end of the filter and a second endcap bonded to a second end of the filter. The areas are arranged concentrically around each other such that the first area is inward of the second area which is inward of a third area and the like. Each area is formed separately and integrity tested separately before final assembly. The first area is slid into the inside of the second area and then the two endcaps are either bonded to each, bonded to a third overall endcap or overmolded by a third endcap.

摘要： A filter system having a filter element ejection device is provided. Filter systems according to the present invention may include a filter element that includes an ejection receiver for receiving actuation action from an ejector of a filter housing. The ejector engages the ejection receiver when a user desires to eject the filter element from the filter housing. Typically, the ejector extends through the filter housing and axially ejects the filter element from the housing.

摘要： A filter cartridge for use in filtering fluids, for example fuel, lubrication, hydraulic and other liquids, as well as air. The filter cartridge is a filter-in-filter design with an inner filter and an outer filter. The inner filter and the outer filter, for example the bottom end plates thereof, are connected to each other via a snap fit connection mechanism. During manufacture, the inner filter can be inserted into the outer filter, with the snap fit connection mechanism retaining the inner filter in the outer filter.

摘要： A fluid filtering apparatus and method may include keyed components to ensure that a correct filter element is being installed into a filter base. Keyed arrangements may occur between a filter element and a filter housing, a filter and a filter base, and a filter base and a filter housing. A locking arrangement may be provided to prevent undesired loosening of a filter relative to a filter base. The filter base may include a torsion lock insert that engages lock detents of a filter to prevent the undesired loosening. An adaptor may be provided to provide the lock detents that interact with a torsion lock insert.
