    Abstract: A jet regulator includes a ring-shaped or sleeve-shaped jet regulator housing, the outlet face side of which is formed as a perforated, grate and/or mesh structure with throughflow openings bordered by flow-guiding walls. The perforated, grate and/or mesh structure on the outlet face side is produced at least in regions and at least on the surface from a manually deformable dimensionally elastic plastic material. The outlet face side of the jet regulator housing is in the form of an outlet disk which can be inserted into the jet regulator housing and which bears the perforated, grate and/or mesh structure. The separate configuration of the outlet disk on the one hand and the jet regulator housing on the other hand facilitates the separate production of said jet regulator constituents even from materials which cannot be welded or otherwise connected to one another, if appropriate in different production processes.

  • Patent number: 8398852
    Abstract: A drainless reverse osmosis (RO) water purification system provides relatively pure water for on-demand dispensing, while recycling brine to a domestic hot water system. The drainless purification system includes a pre-filter catalyst cartridge for removing chlorine-based contaminants from a tap water supply upstream from an RO membrane. The catalyst is regularly refreshed by a high through-flow of water to a conventional cold water dispense faucet, thereby significantly prolonging the service life of the RO membrane. The RO membrane is incorporated into a multi-cartridge unit adapted for facilitated slide-out removal and replacement as needed. A control valve recycles brine from the RO membrane to the hot water system during pure water production, and recirculates tap water through the RO membrane when a pure water reservoir is substantially filled. The multi-cartridge unit may further include an air filtration system for providing a flow of filtered air.

  • Patent number: 6926821
    Abstract: A totalization meter system for a water treatment device, the device having an inlet aperture and an outlet aperture, and a channel for channeling water between the inlet and outlet apertures. A flow reactive device is positioned in the channel and is exposed to the flowing water, and a signal generating member is positioned on the flow reactive device. A switch is positioned proximately to the flow reactive device, and is sensitive to the proximity of the signal generating member. The switch is able to communicate electric signals indicative of the motion of the signal generating member. A resettable processor having a performance threshold programmed therein and an output device is included. The microcontroller is in electrical communication with the switch for receiving electrical signals from the switch. The switch is capable of sensing the characteristics of the flow reactive device and communicates electrical signals representative of the characteristics to the microcontroller.

  • Patent number: 6923908
    Abstract: A filter apparatus for use in liquid chromatography systems includes a housing component having an open channel formed therethrough for operably receiving fluid transfer tubing in at least a first end thereof, a relatively thin mesh filter component, and a securement component configured to matingly engage with the housing such that the filter component is operably disposed and secured between the housing and the securement component adjacent to and superimposed over a second open end of the channel. The filter apparatus is thus adapted to operably filter chromatographic fluids being drawn through the channels from the second open end and into the fluid transfer tubing.

  • Patent number: 6848632
    Abstract: A frusto-conical strainer is mounted on the lower end of a pop-up riser for filtering out debris from water entering the lower inlet end of a surrounding outer housing to prevent clogging of the nozzle orifice or damage to mechanical components within a sprinkler. A cylindrical scrubber including a circumferential array of resilient arms is anchored at the lower inlet end of the outer housing. Wiper blades on the upper ends of the arms press against the outer surface of the strainer to scrape debris and algae therefrom as the riser extends and retracts. The strainer may have finer and coarser mesh sections for different levels of filtering in a sprinkler having multiple internal water flow paths. A plurality of circumferentially spaced projections on the strainer deflect past a plurality of circumferentially spaced ribs formed on the interior wall of the outer housing to provide a riser ratchet mechanism.

  • Patent number: 6797156
    Abstract: A water treatment unit is disclosed which can be mounted directly on the faucet or tap of the user's sink and which contains one or more water treatment media and an operating valve which permits the selection of several operating modes including service, spray and stream modes. In the service mode the water is treated by at least one if not all of the various water treatment media contained in the unit housing after which the water is discharged from the valve of the unit for service use, and the service discharge may be adjusted to direct the treated water as desired by the user. The valve of the treatment unit includes a housing, a stationary member, a slide member and a rotatable switch member unit and may also be operated in a backflush mode in which water may be directed in the reverse direction through at least one of the water treatment media to regenerate that media.

  • Patent number: 6709603
    Abstract: Embodiments of a method and filter apparatus (10) for filtering and/or treating water are shown and described, each embodiment being for multiple-stage processing of water or other liquid, with storage intermediate between the stages. Preferably, water is passed through a first zone (28) of a filter housing cavity and conducted through an intermediate port (16) to storage (24). When water is demanded by a usage device (22), water flows in reverse from storage back into the filter (10), to flow through the second zone (42) for a second stage of filtering/treatment, and then preferably out an outlet port (18) to the usage device. Water may also flow from the water source directly through the first and second zones (28, 42) and to the usage device (22), without intermediate storage. Preferably, both first and second zones are contained and axially arranged within a single filter housing (12).

  • Patent number: RE39142
    Abstract: A showerhead having a water filter element held therein. The water filter element is easily changeable by unscrewing two halves of a body forming the showerhead. The body halves are easily gripped and turned, so as to be opened or closed, and the showerhead preferably includes a massage-type head at the lower end thereof, which may be rotated to vary the streams of water exiting the showerhead. The water filter element cooperates with internal components of the halves of the body to direct the flow of water through the filter element, and then out of the massage head. The showerhead may be easily and quickly adapted to be held on any shower arm, and to replace any existing showerhead without taking up as much room as currently existing filter elements used with available showerheads.
