Various methods and systems are provided for an oil filter system for a vehicle system. In one example, an oil filter system comprises a housing within which a plurality of oil filter elements are disposed and a frame supporting the housing, the frame including one or more mountings configured to support one or more vehicle sub-assemblies.

A solvent reservoir filter for a liquid chromatograph system includes a first screen extending in a first plane, the first screen configured to filter solvent received through the first screen, a second screen extending in a second plane that is parallel to the first plane, the second screen configured to filter solvent received through the second screen, a main body extending between and connecting the first screen and the second screen, and a fluid outlet configured to expel solvent filtered by the first and second screens from the solvent reservoir filter. Methods of use and assembly of the solvent reservoir filter for a liquid chromatograph system are further disclosed.

The invention relates to a filter unit, a filter system (44b) with at least two filter units, and to a motor vehicle with a filter system (44b). A filter bowl (12d-e) of the filter unit is formed by a base and a cover. Embodied in a side wall of the base are at least two access openings to an antechamber or collection chamber (34a-b) in the filter bowl (12d-e). Embodied integrally with the cover is a collection line segment or supply segment (26d-e) that leads from a clean chamber or an unfiltered side antechamber in the filter bowl (12d-e) to at least two open ends (28l). The inventive filter system (44b) has at least two inventive filter units, and fluid may flow through their filter elements (30, 30a-d), which are switched in parallel. The invention facilitates the space-saving arrangement of filter units and filter systems (44b) in constricted and/or complexly shaped installation spaces, especially in motor vehicles.

A filter assembly for a fluid to be filtered, in particular fuel or oil, has a filter housing having a housing lower part that is configured as a single piece and has at least one fluid inlet for the fluid to be filtered and a plurality of filter pots that are arranged next to one another side by side in a shared plane and are fluidically connected to one another via side wall passages An upper housing part closes the filter pots and has a fluid manifold that has at least one fluid outlet for the filtered fluid flowing out from the filter pots. At least two filter elements, one being arranged in each of the filter pots of the filter housing. The filter assembly is a more inexpensively-manufactured and as configured for installation even in confined installation spaces, so as to accommodate a sufficiently large filter surface for a predetermined volume flow of a fluid to be filtered.

A filter element for filtering a fluid has a first filter medium arranged in annular shape and surrounding an interior. A second filter medium is provided, wherein the first filter medium and the second filter medium separate a clean side of the filter element from a raw side of the filter element. The first filter medium and the second filter medium are arranged such that a fluid to be filtered flows from the raw side of the filter element to the clean side of the filter element in parallel through the first filter medium and the second filter medium. The first filter medium is liquid-permeable and gas-impermeable and the second filter medium is liquid-impermeable and gas-permeable.
