A spin-on fluid filter with improved attachment and sealing with the filter head. The filter has a gasket positioned at the end of threads used to connect the filter to a filter head. The described design protects the gasket from excessive engine heat, cat or tear damage during installation, and the roll out effect of installation torque. In addition, the described attachment provides gasket protection and uniform compression of the gasket. The gasket can be any type that provides a seal which keeps external threads on the filter and the filter head dry.

The present invention relates to a filter device for separating debris from a fluid. The filter device includes a housing having at least one inlet, at least one first outlet, and a second outlet. The filter device further includes a filter cartridge that allows fluid to pass therethrough but prevents passage of debris therethrough. The filter cartridge is positioned within the housing so as to define an upper chamber and a lower chamber within the housing. The at least one inlet is positioned so as to allow contaminated fluid to enter the lower chamber of the housing. Fluid must pass through the filter cartridge in an upward direction to reach the upper chamber, and the first outlet is positioned so as to allow filtered fluid to exit the upper chamber. The second outlet is positioned to allow debris accumulated within the lower chamber to be discharged.

A filter cartridge assembly for an ice making appliance having a rectilinear filter cartridge with a plurality of partitions that are positioned within an internal chamber, form multiple sub-chambers, and create a non-linear pathway for the flow of water through the filter cartridge. Filter media positioned in the sub-chambers of the filter cartridge are configured to remove dissolved solids from water travelling through the filter cartridge and used by the appliance to create ice, including clear ice.

A beverage dispenser comprising: a cartridge receiving chamber 108, the chamber comprising a water inlet 112 and a treated water outlet 114 configured to connect to a cartridge water inlet and a treated water cartridge outlet of a water treatment cartridge, respectively; a cartridge seat 116, slidingly displaceable within the cartridge receiving chamber 108 between a cartridge operative position in which the cartridge water inlet and the treated water cartridge outlet establish a fluid communication with the water inlet and the treated water outlet of said chamber, respectively, and a cartridge extraction position in which the cartridge water inlet and the treated water cartridge outlet are disengaged from the water inlet and the treated water outlet of the chamber, respectively, the cartridge seat configured to engage a seat-receiving location formed at an external wall portion of said cartridge when received within the cartridge receiving chamber; and a user accessible actuation member 120 switchable between a locked position and an unlocked position, the actuation member being configured to slidingly displace the cartridge seat between said cartridge operative position, corresponding to said locked position, and said cartridge extraction position that corresponds to said unlocked position.

A filter system for liquid has a filter head with drainage channel and stop element. A filter cartridge is mounted by screw-in movement at the filter head and has a support ring rotatably fastened to its housing part. The support ring has an eccentric closure element and a first positioning element guided toward the stop element by the screw-in movement to position the support ring at the filter head in a rotational position for axially aligning closure element and drainage channel. The closure element is transferred axially into a sealing seat at the filter head to close the drainage channel when screwing on the filter cartridge. The support ring has a second positioning element holding the support ring in a rotationally fixed position at the filter head when unscrewing the filter cartridge so that the closure element is moved out of the sealing seat only in an axial direction.

A water filtration system and water filtration system head provide interchangeable water inlet and outlet ports, so that a direction of a flow of water through the water filtration system can be reversed by configuring a valve provided in the water filtration system head that attaches to a cartridge housing containing a water filter cartridge. The head has a first fluid channel communicating with a fluid volume between the cartridge housing and the outer surface of a water filter cartridge, a second fluid channel in communication with an inside of the cartridge, and a multi-position valve that either conducts inlet water from a first port to the first fluid channel and conducts outlet water from the second fluid channel to the second port, or conducts inlet water from the second port to the first fluid channel and conducts outlet water from the second fluid channel to the first port.

Provided is a filter-attached cartridge which is inexpensive and has high productivity. This filter-attached cartridge has: a first resin mesh which is an integrally molded body having a plurality of ribs arranged therein in a lattice shape; and a cylinder formed in a cylindrical shape so as to surround the first mesh.

A filter for hydraulic fluids including a container defining inside a housing compartment fluidically communicating with an inlet and an outlet associated with and a filtering cartridge, and partitioning the compartment in first and second chambers. The cartridge is configured and positioned for determining the filtering of the hydraulic fluid from the inlet which flows from the first to the second chambers. The container exhibits an engagement portion projecting inside the housing compartment and defining a collar having an outer coupling lateral surface, while the filtering cartridge exhibits a respective engagement portion defining a respective collar exhibiting an inner coupling lateral surface configured for engaging outside the outer coupling surface of the container. The coupling surface of the engagement portion of the container exhibits a polygonal cross-section; the inner coupling surface of the engagement portion of the cartridge is at least partially countershaped to the coupling surface of the container.

A reverse osmosis prefilter system includes a recirculation chamber for accommodating one or more prefilter cartridges. The recirculation chamber is communicably interconnected to an inline water source and an RO filtration membrane. The recirculation chamber has a recirculation outlet and inlet which are communicably interconnected by an offline pump that recirculates prefiltered water repeatedly through the recirculation chamber and prefilter cartridges to remove particulates from the source water prior to delivery to the reverse osmosis filter membrane.

A mechanical interlock system for a fluid filter is described herein. The mechanical interlock system may include a filter cartridge and a filter cartridge manifold for receiving the filter cartridge. The filter cartridge may include a filter body, a fluid inlet and outlet, and an integrated locking head. The integrated locking head may include a key extending radially outward from the integrated locking head and channels on an outer surface of the integrated locking head. The filter cartridge manifold may include an insertion and extraction tube for receiving the key and latching mechanisms. The insertion and extraction tube may include a primary keyway and a secondary keyway. The key, keyways, latching mechanisms, and/or channels may interact to maintain alignment of the filter cartridge during insertion of the filter cartridge into an appliance including the filter cartridge manifold.
