A water filter cartridge has an end cap with separate inlet and outlet nozzles connected to the end of a cylindrical tube that extends from the end cap. The nozzles are slanted and laterally offset from the cylindrical tube. A cam surface on the outer side of the nozzles actuates valves in a mating manifold. The passage in the nozzles is conical, expanding toward the nozzle end and opening onto a portion of the nozzle side to form a sharper tip. Expanding ice pushes itself out of the conical passage and facilitates ice removal. The narrow end of the conical passage facilitates breakage and removal of ice from the nozzle.

A self-back flushing filtration assembly includes an inner container, an outer container, and a filter cartridge. The inner container is configured to receive treated water by way of a filter cartridge. The outer container is configured to hold untreated water and sleeve the filter cartridge and the inner container. The inner container and the filter cartridge are moveably positioned within the outer container to compress and draw the untreated water through filter media within the filter cartridge by way of a filter cap. The filter cap is movably positioned within a cavity of the outer container to draw treated water from the inner container through the filter media of the filter cartridge.

A fuel filter assembly includes a filter housing defining a cavity, a center stack having a base component and a top portion. The center stack is positioned within the cavity of the filter housing and attached to the housing, the center stack having an axial aperture in the top portion, the axial aperture having a circumferential surface, and a fuel filter. The fuel filter includes a filter base, an end cap having a top surface and a bottom surface opposite the top surface, an axial extension that extends from the bottom surface, and at least one prong attached to the axial extension, the at least one prong having an axial surface facing away from the top surface that axially locates the fuel filter in the housing against the circumferential surface, a filter element attached to the bottom surface of the end cap, and a pin attached to a filter base.

A water providing station having a housing that supports a basin. A water dispensing mechanism is associated with the basin and is coupled to a water supply line located within the housing. A filter is also coupled to the water supply line. Mounted to a portion of the housing is a door that is moveable between open and closed positions. The filter is mounted to and supported by the door for movement moved with the door between the open and closed positions.

A fluid filter for a motor vehicle includes a filter housing and a filter cartridge which is fixable on the filter housing by rotating around a longitudinal axis of the filter cartridge. A holding element having a web is disposed on an end plate of the filter cartridge where the web protrudes from a wall of the holding element and where the wall is formed as a spiral shape. The web of the holding element is engageable behind a holding web of a counter bearing disposed on the filter housing that is spiral shaped. The holding web has an incline in a rotational direction in comparison to an abutment region of the filter housing on which a sealing element of the filter cartridge abuts.

A filter cartridge including catches for ejecting the filter cartridge from a filter housing as the filter cartridge and filter housing are removed from a filter base is provided. The catches are configured to engage corresponding catches of the filter base to limit axial motion of the filter cartridge as the filter cartridge and filter housing are threadedly removed from the filter base.
