Abstract:
A modular water filter assembly is disclosed. The modular water filter assembly includes a primary module having primary filter media for treating water; a secondary module having a first end and a second end; and a manifold defining an inlet connectable to a water source, and an outlet connectable to a water dispenser. The secondary module is removably coupled to the manifold at the first end thereof, and to the primary module at the second end thereof, the secondary module defining a flow path for carrying water therethrough. The water filter assembly is variably configurable for treating water passed from the water source through the inlet of the manifold and through at least one of the primary module and the secondary module and then through the outlet of the manifold. An appliance incorporating such a modular water filter assembly is also disclosed.
Abstract:
A system for removing sediment from water is disclosed. The exemplary embodiments described herein disclose a system comprising a filter chamber, having a deck positioned inside to divide it into an upper chamber and a lower chamber. The deck may have a plurality of holes to hold filtration elements and also may have a ridge or a skirt or both. An inlet line may be tangentially connected to the filter chamber and introduce influent liquid into the filter chamber below the deck and outside of the skirt.
Abstract:
The present disclosure pertains to a fluid filter having integral attachment means which may take the form of a threaded portion of a filter cartridge. The threaded portion threadably interacts with a complementary threaded portion of a filter mounting to retain the filter cartridge to the filter mounting. The disclosure also pertains to a fluid filter having a cartridge made from two plastic shells welded together. The disclosure also pertains to a fluid filter with filter media positioned within a filter cartridge by an end cap with extending ribs welded to one of the two shells which compose the filter cartridge.
Abstract:
A liquid filter suitable for motor vehicles which includes a filter head (11), a vessel (12) and a filter element (16) disposed within the vessel (12) sealingly separating an inlet (14) from an outlet (15) such that liquid from the inlet must flow through the filter element to reach the outlet. The filter element (16) has guide projections (27, 28) positioning the filter element (16) within the vessel (12). Prior to installation, the filter element (16) is preassembled into the vessel (12) and fixed in position by pushing the filter element (16) into an element guide (29), after which the preassembly is screwed onto the filter head (11). When the vessel (12) is unscrewed from the filter head (11), the filter element (16) slides out of the element guide (29) and moves axially upwardly to free a volume V. Liquid flowing into the vessel (12) from the higher regions of the liquid filter (10) can flow into this volume, thus enabling drip-free replacement of the filter element.
Abstract:
A filter assembly includes a head, a filter housing which can be connected to the head, and a filter element which can be received in the filter housing. The filter element includes a tubular wall provided with a filtration medium; a first end part provided at a first axial end of the filter element; and a second end part provided at a second axial end of the filter element. The second end part of the filter element is provided with a either a protrusion or an undercut opening, on the one hand, and the second end of the housing is provided with either an undercut opening or a protrusion, on the other hand. A side of the protrusion or opening is provided with a sloping face which slopes at a slope with respect to the axial direction of the filter element.
Abstract:
A filtration system is disclosed comprising a filter manifold and a filter cartridge. The filter manifold comprises a bracket, a valve, a manifold feed port, a manifold filtrate port, and a handle. The valve is held by the bracket and comprises a fixed portion attached to the bracket and a rotary portion. The handle is operatively connected to the rotary portion and comprises a cartridge lifter having one of a camming ramp or a camming lug lifter engagement feature. The handle is rotatable to a service position and a disengaged position, wherein the manifold feed port is blocked by the valve when the handle is in the disengaged position. The filter cartridge comprises a cartridge feed port, a cartridge filtrate port, and an external cartridge surface having one of a camming lug or a camming ramp for engaging the lifter engagement feature.
Abstract:
A filter with quick disassembly mechanism includes a hollow cylinder having an open top and an open bottom, the cylinder comprising a lower extension including a plurality of flanges equally spaced apart along an outer surface, each flange having an inclined top surface; and a funnel comprising a mouth adapted to receive the cylinder, a hollow stem extending downward and communicating with the mouth, a plurality of stop members equally spaced apart along an annular edge of an inner surface of the mouth, an annular platform projecting inward from the mouth to be adapted to support the cylinder, a plurality of gaps each defined between the stop member and the platform, the height of each gap being greater than one end of the flange but less than the other end of the flange. Clockwise turning the cylinder a predetermined angle will assemble the cylinder and the funnel.
Abstract:
An apparatus for filtering water has an interface and a filtration/purification canister removably mountable thereon. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly form the outlet port to the appliance instead. A flapper valve is provided in the canister to prevent back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface. The flapper valve also is provided with an actuating means to automatically open the flapper valve when the canister is mounted on the interface, which permits fluid to be drained from the canister when the fluid distribution system is being drained without disconnecting the canister from the interface.
Abstract:
A method of connecting filter cartridge 30 with filter cover 10 by using an intermediary element 20, wherein the intermediary element 20 includes a filter element retainer 25, an internal outlet connection 26 and a support 23. A first fastener A 22 is mounted at edge of the support 23, and a second fastener B 32 is fixed on an internal wall at the top of the filter cartridge 30. By means of fastening fastener A 22 to fastener B 32, the middleware 20 is firmly combined with the filter cartridge 30. A water outlet passage 16 disposed in the filter cover 10 is matched to the internal outlet connection 26. By connecting screw A 28 on the internal outlet connection 26 with screw B 18 on the water outlet passage 16, the intermediary element 20 is firmly fixed to the filter cover 10.
