A connecting structure connects a filter housing to a filter housing retaining structure. The connecting structure conducts a liquid that is to be cleaned to the filter housing and discharges a purified liquid. The connecting structure includes a filter housing cover that connects to the filter housing and that receives a filter medium. The filter housing cover has attachment elements that connect to corresponding attachment elements of the filter housing retaining structure to establish an exchange of fluids between the filter housing retaining structure and the filter housing. Filter housing cover guides are on opposing sides of the filter housing cover; and guides on the filter housing retaining structure engage the filter housing cover guides when connecting the attachment elements of the filter housing cover with the attachment elements of the filter housing retaining structure to support and linearly guide the filter housing cover during the connection process.

A filter device has a filter housing and a clamping bracket engaging around the filter housing. The clamping bracket includes a bracket and a clamping collar that are swivelably coupled by a hinge, the bracket and the clamping collar being positively connected adjacent to the hinge through the engagement of a projection into an engagement window.

A filter assembly that includes one or more features that enhance installation, inspection, and replacement of the filter is provided. In one exemplary aspect, the filter assembly includes a manifold and a filter media assembly that includes a filter media and an end cap attached thereto. The end cap and manifold include features that provide for secure mounting of the filter media assembly with the manifold so as to facilitate inspection, installation, and removal of the filter assembly.

A filter insert for a filter for filtering a fluid having] an inflow surface, and outflow surface, and a main throughflow direction. A filter body of the insert has a filter medium with pleats forming a pleated bellows, are arranged perpendicular to the main throughflow direction. A first number of the pleat edges form the outflow surface and a second number of the pleat edges on a pre-filtration side of the filtration body form the outflow surface. A first seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration on a surface formed by a first number of of end face of the pleats. A second seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration side on a surface formed by a second number of end faces of the pleats.

A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.

Certain embodiments include a screen assembly of a vessel, where the screen assembly includes a plurality of fixed elements and a retainer, and the retainer includes a ring, a plurality of wedges disposed about the ring, and a plurality of keyholes at spaced locations about the ring.

Each keyhole includes a bore and a slot extending from the bore into an adjacent wedge of the plurality of wedges, the slots have a width less than the bores, and the retainer may receive the fixed elements through the bores and may be rotated in a relation with the plurality of fixed elements to bring the plurality of fixed elements into simultaneous engagement with the wedges.

A water tank for a domestic appliance, having a connection for a filter cartridge, wherein an annular tank sealing surface is provided on the tank base for the sealed connection of the filter cartridge and the tank sealing surface encloses a tank passage opening for the water to flow out of the filter cartridge through the wall of the tank base to the domestic appliance, wherein the tank sealing surface has a varying radius along its circumference in relation to a central axis, such that the tank sealing surface comprises radial indentations and/or radial protuberances, wherein the radial protuberances and/or radial indentations of the tank sealing surface have a round profile.

A filter cartridge for the use in the interior of a water tank of a domestic appliance having a filter housing of which the wall separates in a watertight manner a housing internal side from a housing external side, wherein a filter inlet opening which in the operating position of the filter cartridge is disposed on the lower end region of the latter and is open in relation to the external environment of the filter housing is provided, wherein provided downstream of the filter inlet opening in terms of the flow direction of water during operation, in the interior of the filter housing, is a device for water conduction which comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet line for suctioning water from the filter cartridge.

An oil filter adapter device may be used to enable an engine or other machine that was manufactured for using cartridge oil filters to use spin-on oil filters. In some examples, the oil filter adapter may have a docking collar for coupling with an engine, a cylindrical base for coupling with an oil filter housing, and an attachment piece for coupling with a spin-on oil filter. The oil filter adapter may also have a spring disposed between the docking collar and the cylindrical base such that the docking collar is compressible relative to the cylindrical base to allow the oil filter adapter is able to couple to a variety of oil filter housings ranging in size and shape.
