A filter device having a filter housing (14), consisting of a housing pot (12), which accommodates a replaceable filter element (16) and is closed by a removable lid part (32), wherein the element material (20) of the filter element (16) separates an unfiltrate chamber (22) from a filtrate chamber (18, 43), and having a measurement sensing device (108) for sensing pressure values from at least one of the chambers (18, 22, 43) is disclosed, which is characterized in that the measurement sensing device (108) is disposed on a lid inner side (45) of the lid part (32) and at least partially guided therein, projects into the filter housing (14) and in that at least parts of a measurement value evaluator (78) connected to the measurement sensing device (108) are disposed on the opposite lid outer side (42) facing the environment.

The disclosed filter element is configured for use within a housing of a filter assembly. The filter element includes an obround ring of filter media extending between an upper and lower endcaps and defines a dirty wet fuel region. The upper endcap of the filter element defines an inlet for receiving the dirty wet fuel, which flows into the dirty wet fuel region and radially outward through the filter media. The upper endcap may include an insert to define a flow chamber to distribute fuel into the dirty wet fuel region. A clean wet fuel region is defined outside the filter element and within the housing. After flowing through the inlet and the filter media clean wet fuel fills the clean wet fuel region. A water separator is disposed external to the filter media and defines a clean dry fuel region in communication with an outlet defined by the upper endcap.

An IC tag is attached to a filter element and a contact of the IC tag with liquid is avoidable. An IC tag is provided inside an upper plate provided so as to cover an upper end surface of a filter medium in a filter element. A lid body is provided on the case into which the filter element is inserted, and an antenna is provided on the lid body.

A filter element having a central axis includes a first endplate having a first central aperture, a second endplate having a second central aperture, a filter material positioned between the first endplate and the second endplate and having an axial passageway extending therebetween and along the central axis, the axial passageway axially aligned with the first central aperture and the second central aperture. The filter element includes a plurality of fingers attached to the first endplate and positioned circumferentially about the central axis and extending parallel therewith, each finger having a lip that extends from a surface of its respective finger for axial engagement with a respective nodule, of a plurality of nodules, of a filter head.

A filter device, in particular for lubricating oil filtration, includes at least two filter inserts (27), in each of which a filter material (43) is accommodated. The filter inserts are provided with fluid passage points (37, 39) and can be stacked on top of one another with the formation of a stack. A back-flushing device (55,57) is movably arranged along the inner side of the filter inserts (27). The individual filter inserts (27) are designed as identical parts at least with respect to their housings.

A filter device with a removable termination part (81; 82) and a housing (3) that receives a replaceable filter element (5) having two end caps (25,47). Between the end caps, a filter material (12) extends. A positioning device (65) is arranged between the termination part (81; 82) and one end cap (47). The positioning device positions the filter element (5) within the housing (3), at least when viewed in the circumferential direction of the filter element, in interaction with at least one corresponding positioning element (71) of the end cap (47).

A bearing housing assembly featuring a bearing housing having a bearing housing wall portion with a bearing assembly chamber for receiving a bearing assembly and a shaft to be rotated, an oil sump for receiving and containing oil for lubricating the bearing assembly when the shaft is rotated, an oil path channel formed as an oil path for receiving dirty oil from the bearing assembly chamber for traveling down the oil path, and a filter assembly wall portion forming a filter assembly cavity coupled fluidically between the oil sump and the oil path channel; and a filter assembly arranged in the filter assembly cavity, to couple to the filter assembly wall portion, receive the dirty oil traveling down the oil path, filter the dirty oil and provide filtered oil to the oil sump, so the filtered oil can be recirculated to lubricate the bearing assembly when the shaft is rotated.

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. 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 portions of the outer enclosure.
