Abstract: A filter device has a filter housing (14) with a housing pot (12), which accommodates a replaceable filter element (16) and is closed by a removable lid part (32). The element material (20) of the filter element (16) separates an unfiltrate chamber (22) from a filtrate chamber (18, 43). A measurement sensing device (108) senses pressure values from at least one of the chambers (18, 22, 43), is disposed on a lid inner side (45) of the lid part (32), is at least partially guided in the lid part, and projects into the filter housing (14). At least parts of a measurement value evaluator (78) are connected to the measurement sensing device (108) and are disposed on the opposite lid outer side (42) facing the environment.

Abstract: A filter element including a canister, media, and a spinning disc element is provided. The canister circumscribes a central axis. A tap plate is at an end of the canister having a central threaded opening along the central axis of the canister. The tap plate includes a first outer opening radially spaced between the central opening and a periphery of the tap plate. The disc element is supported for rotation on the tap plate. A first keyed protrusion projects outwardly from the disc element. The keyed protrusion defines a first flow opening. The spinning disc element is rotatable about the central axis. The first outer opening is in fluid communication with the first opening of the first keyed protrusion such that fluid can into or out of the canister. Filter systems including a filter head to which the filter element may be mounted are also provided.

Abstract: A filter element has a first follower element with a first traction surface and a second follower element with a second traction surface provided for interacting with first and second mating surfaces of the filter housing, respectively. The first and second traction surfaces interact with the first and second mating surfaces to pull out the filter element from the filter housing. The first and second traction surfaces are spaced apart from each other along a longitudinal axis of the filter element and project radially into the interior of the filter element. At least one of the first and second follower elements has a stop surface adjoining circumferentially the respective traction surface. In a position of use, the stop surface interacts with a counter stop surface of the filter housing to form an at least unidirectional rotational degree of freedom blocking about the longitudinal axis relative to the filter housing.

Abstract: A removable filter apparatus for a laundry treating appliance includes a lifter cover defining a generally trapezoidal prism shape with an open rectangular bottom. The lifter cover is configured to be slidably attachable along the rectangular bottom to a lifter base attached to an inner circumferential surface of a drum of the laundry treating appliance. The lifter cover defines through openings to allow for free flow of water. The apparatus further includes a filter element attachable to the lifter cover and sized to fit within the lifter cover to allow the filter element to capture particulate within the water flow.

Abstract: A top load liquid filter assembly includes a filter lockout mechanism to ensure that the filter base and cover are not connectable unless there is a proper filter cartridge installed therein. The filter system can also include an automatic drain mechanism and a cartridge retention mechanism. One example embodiment further includes an air bleed vent. A filter cartridge usable in the topload liquid filter assembly includes first and second protrusions and cover-gripper members. Methods of use, installing, servicing, and retaining can be practiced.

Abstract: A filter device may include a filter housing with a filter housing pot and a cover screwable onto the filter housing pot, and an annular filter element arranged in the filter housing and having an axially protruding pin for closing a run-off channel. The annular filter element may be connected to the cover via a first thread, which may have a dome protruding centrally and axially from an upper end disc of the annular filter element, with an outer thread interrupted by free passages, and hollow cylindrical spring elements, which may protrude axially from the cover and on which an inner thread portion designed to complement the outer thread may be arranged. Each inner thread portion may extend over a longer circumferential portion than one of the free passages. The first thread may be designed running counter to a second thread arranged between the filter housing pot and the cover.

Abstract: 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.
