Abstract: A reverse osmosis filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with the raw water ingress, permeate egress, and reject water egress. The reverse osmosis filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

Abstract: The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator.

Abstract: A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

Abstract: A snorkel (10) having a double shell core (16, 26) that defines an annular gap (40) between the shells and that has an array of baffles (66) arranged in the annular gap to define a serpentine flow path for cooling gases that pass through the annular gap. In an embodiment, a snorkel includes a flange (12) that defines an internal passageway (84) such that the fluid pathway through annular gap (40) includes passage of cooling medium through internal passageway (84).

Abstract: A proportioning valve for a reverse osmosis system that controls the production of product water by the differential pressure across the purification membrane. By sensing increasing tank pressure to actuate the proportioning valve, the flow of waste water is restricted. Placement of seals within the cavity of the valve, as well as placement of waste water inlet and outlet ports, protects tension components that provide reverse tank pressure from waste water exposure. A needle valve assembly responsive to an actuating assembly that senses tank pressure removes the need for an inlet tank water port while restricting water flow.

Abstract: The present invention presents a removably secured seal for forming a second stage water-tight seal within a two stage cavity filter head assembly for mating with a complementary manifold having cylindrical (male) bayonet ports. The seal includes a base circumferential seal having a center aperture and sidewall members extending axially upwards from the base seal; the sidewall members being insertable within cavities or slots formed in the second stage recess cylindrical cavity sidewall.

Abstract: A stabilizer for suppressing vibration, shock, translational, and rotational forces, on a dual cartridge filter system. The stabilizer uses opposing curved surfaces which correspond with, and follow the curvature of, the diameter of each cartridge cylindrical housing. The stabilizer is formed having a stabilizer base with locking members or leg portions radially extending along a bottom portion of each opposing curved surface. The stabilizer is secured to each filter housing by having the locking members inserted within indents on a rim of the filter housing bottom end cap. In alternative embodiments, the locking member is a resilient tab that forms a friction fit with a complementary structure on the filter housing bottom end cap, or an interlocking snap-fit male/female clip complementary to a female/male clip or snap on the filter housing lower cap.

Abstract: Filters for use in conjunction with valves of the faucet or spigot type, and to filters for use in devices for withdrawing liquids from containers at relatively low pressures, such as gravity feed jugs or other gravity feed reservoirs. A ¼-turn attachment scheme for connecting a filter cartridge to a gravity feed reservoir, such as within a beverage making/dispensing device.
