A water filter cartridge assembly for fluid filtration which may be attached to, and removed from an appliance water filter manifold assembly of an appliance, typically by a push-actuated release. The water filter cartridge assembly has a filter housing, and an ingress port and egress port extending therefrom. Each of the ingress port and the egress port typically comprise a port portion having a varying radial diameter. The water filter cartridge assembly further comprises a connection assembly that is structured to establish an electrical connection between the connection assembly and a controller of the appliance. Both of said ingress and egress port have at least one aperture for the passage of fluid therethrough such that each of the at least one aperture is exposed in a direction facing away from the connection assembly.

A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a filter 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 housing assembly may be attached to, and removed from, a 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.

In a device for separating solid particles from liquids and gases in flexible disposable plastic containers, a plurality of filter elements, consisting of flat, elongate support grids with filtrate drain channels and a covering, all-round closed filter medium, are connected to form a filter package and enclosed by a flexible plastic container. This disposable filter system is operated in a pressure vessel and can be compressed there by applying an external pressure in such a way that the residual volume of the suspension is considerably reduced. As a result of the stable design, backwashing of the filter elements is possible, which prevents the build-up of a dense layer of solid particles and can therefore lead to increased filtrate flow. As a result of the completely sealed, sterile filter elements, the increased filter surface area and the resulting high filter efficiency and complete filtration with reduced residual volume shares, this system proves to be a cost-effective filtration device with high flow rates, minimized cleaning costs and short changeover times when changing products.

A valve unit has a plate-shaped valve body with a closure section and a connection section. The valve body has a cutout surrounded by a frame. The closure section has a closure tab that, beginning at a first fastening section at the frame, projects into the cutout. The connection section, beginning at a second fastening section at the frame, projects into the cutout and has a contact tab and a fastening point. The first and second fastening sections are arranged opposite each other at the frame along a longitudinal axis of the valve body. A filter head for the valve unit has a valve seat for a seal body of the closure section of the valve body. A fastening pin of the filter head fastens the connection section of the valve unit. A contact region of the filter head contacts a positioning region of the valve unit.

A pool filter system includes a filter housing with an open interior. A pleated filter container in the open interior of the filter housing has a pleated filter side wall and divides the interior of the filter housing into an pleated filter compartment and an particulate filter compartment surrounding the pleated filter side wall. The pleated filter side wall has a plurality of pleated filter container openings. A particulate filter medium is within the particulate filter compartment, and a pleated filter is within the open interior of the pleated filter compartment. A water inlet communicates with the particulate filter compartment, and a water outlet communicates with the pleated filter compartment. The pleated filter container openings in the pleated filter container side wall have a dimension that is less than the diameter of the particulate filter medium. A backwash assembly and a method of filtering pool water is also disclosed.

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.

A head made of metal is provided covering an opening of a filter case, and a filtration member having a tubular shape is provided in an internal space formed by the filter case and the head. A plate made of metal is provided near the opening of the filter case, and an IC tag is provided between the filtration member and the plate. The head is provided with an antenna unit including an antenna section including an antenna configured to communicate with the IC tag. The antenna unit includes a case having a rod shape and at least partially inserted into the head, the antenna section is provided adjacent to a first end corresponding to one end of the case, the case is provided in the head such that the antenna section is exposed when the head is viewed from a side of the filter case, and the plate is provided with an aperture from which the IC tag is exposed.

Both of said ingress and egress port have at least one aperture for the passage of fluid therethrough such that each of the at least one aperture is exposed in a direction facing away from the connection assembly.

One or more techniques and/or systems are disclosed for a vehicle fluid filter head. The filter head can be attached to two or more filters to filter vehicle fluid, and provide a variety of optional arrangements for coupling inlet and outlet hoses. A plurality of inlets and outlets can be disposed on the filter head at different sides of the filter head. A pair of filter headers can be disposed on a first side to receive filter. A first inlet and outlet can be disposed on a second side, and a second inlet and outlet can be disposed on a third side. Respective inlet are fluidly coupled with an inlet passage in the head, which is fluidly coupled with an intake portion of the filter headers. Respective outlets are fluidly coupled with an outlet passage in the head, which is fluidly coupled with an outflow portion of the filter headers.

A filter base for receiving a complementary mating filter housing assembly. The filter base includes a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the filter housing assembly. The wire harness assembly includes conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The connector housing has an upper surface and an oppositely facing lower surface and is dimensioned to receive a first end portion of the one or more contacts. The contacts are flexible from a first position to a second position when a mating portion of the one or more contacts engages a mating connection surface of the filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact mating portions are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.
