The contacts are flexible from a first position to a second position when a mating portion of the one or more contacts engages a mating connection surface of the filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact mating portions are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

An assembly system for components of a pressurized fluid supply system for an agricultural vehicle includes a body having at least one fluid duct connectable at one end to a pressurized fluid supply and having a socket at the other end. A detachable component such as an accumulator or oil filter is connectable in releasable mechanical engagement with the body to receive pressurized fluid from the at least one fluid duct. The engagement results from insertion of at least a portion of the component into the socket and rotation of the component to a locked position. The body has at least one discharge duct extending therethrough. In a partially rotated position of the component portion within the socket, the component remains mechanically attached to the body and the fluid duct and discharge duct are in fluidic connection, discharging accumulated pressure in the fluid duct.

Disclosed is a filter coupling device having joint members, a base plate, a filter holder, a rotation shaft, and a leg. The filter holder allows support of a first filter and a second filter. The rotation shaft is connected with the filter holder. The filter holder takes a first attitude and a second attitude by rotating around the rotation shaft. The filter holder includes a first filter holder configured to support the first filter in the first attitude, and a second filter holder configured to support the second filter in the second attitude.

A quick change oil filter includes a filter canister and filter base that may be installed and removed manually from an engine adapter on an internal combustion engine. The filter canister and filter base may hold at least about one third of the required engine oil supply when removed from the engine adapter. The engine adapter includes an oil inlet passage, an oil outlet passage, and a filter base mounting cavity. A check valve is biased to close an oil outlet opening from the filter canister, trapping oil inside the filter canister when it is removed from the engine adapter.

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 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.

A filter cartridge for use in the interior of a water tank of a household appliance, the wall of which separates a housing internal side from a housing external side. A filter inlet opening which in the operation of the filter cartridge is open in relation to the external environment of a filter housing. A device for water conduction comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet opening for suctioning water from the filter cartridge in the interior of the filter housing, downstream of the filter inlet opening relative to the flow direction of the water during operation. A filter port has an annular filter sealing face for the connection of the filter cartridge in a water tank. The filter sealing face has a separately disposed filter-proximal guide structure for receiving a centering element for centering the filter cartridge.
