  • Patent number: 10737203
    Abstract: A compact shower water filter assembly for holding a water filter element therein. The water filter element is easily changeable by unscrewing two halves of a body forming the filter assembly. The body halves are easily gripped and turned, so as to be opened or closed. The upper half of the body is internally threaded to engage the shower arm, and may pivot about the shower arm. The bottom half of the water filter assembly may include a showerhead, converting the shower water filter assembly, into a filtered showerhead assembly. The shower water filter assembly may be easily and quickly adapted to be held on any shower arm, and to replace any existing shower water filter without taking up as much room as currently existing shower water filters.

  • Patent number: 7617996
    Abstract: A spraying head for bathing comprises an outer housing and an inner housing. In a center of a top edge of the outer housing is mounted a locking seat having plural water outlet openings and outer threads, and an engaging section mounted with a water-stop ring is formed on a lower end of the locking seat. The inner housing is mounted in the outer housing, and the inner housing is combined with a water outlet panel and is mounted with a locking assembly having inner threads and an abutting flange. The inner threads of the locking assembly are threaded with the outer threads of the locking seat in such a manner that the abutting flange is abutted against the water-stop ring, so as to form a sealing condition. And a bolt cooperates with a spacer and a nut enabling the water outlet panel to fix in the locking seat.

  • Patent number: 7578453
    Abstract: A handshower is disclosed providing two different radial spray patterns that can be selectively operated. There is a handle adapted for connection to a water supply, a nozzle head having an outer sleeve and an inner chamber connected to the handle, and an axially extending waterway positioned in an inner chamber of the nozzle head. On the sleeve there is an array of outlets running from the inner chamber to an outer radial face. The waterway has an axially extending channel and multiple sets of radially extending orifices. The sleeve is rotatable relative to the waterway from a first position where the channel is in communication with a first group of outlets to a second position where the channel is in communication with at least some of the outlets that are not in the first group.

  • Patent number: 7481381
    Abstract: A compressed natural gas fuel injector including a housing, an inlet, an outlet, a seat, a closure member, and an attached nozzle. In a preferred embodiment, the inlet and outlet communicate a flow of gaseous fuel regulated by the closure member. The gaseous fuel passes through the seat, which is coupled to a rim surface of a retainer portion of the attached nozzle, and into a flow passage that further communicates the flow of gaseous fuel into one or more flow channels. The orientation of the flow channels within the attached nozzle greatly affects the discharge pattern and mixing characteristics of the gaseous fuel within an intake manifold. A method of flowing gaseous fuel through the fuel injector is also described.

  • Publication number: 20080203197
    Abstract: Disclosed is a shower head comprising a housing-type first part (T1) inside which a water duct extends. One end of said water duct communicates with a water inlet. The first part (T1) is connected to a second part (T2) that is embodied as a discharging element. The receiving space of the discharging element communicates with the other end of the water duct in at least one mode of operation of the shower head. In said mode of operation, the external edge of the second part (T2) forms an overflow edge in one region, via which water can flow off. The second part (T2) forming the discharging element is composed of a top portion and a bottom portion, between which an interior space is located that communicates with the second end of the water duct in a second mode of operation of the shower head. A plurality of nozzle-type discharge ports (A2) are arranged in the bottom portion of the second part (T2).

  • Patent number: 7389951
    Abstract: A misting spray nozzle includes a hollow body having an interior wall descending from an upper end to a lower end. The interior wall tapers toward the lower end to form a choke. A channel section provides two fluid paths descending from an upper central aperture. A turbine is sized and shaped to fit closely within the choke and has spiral grooves on its outer surface. The turbine attaches to the body at its upper end and has a cone-shaped opening at its lower end. A conical core is sized and shaped to fit closely within the cone-shaped opening and has grooves spiraling in an opposite direction on its outer surface. The core is attached at its upper end to the turbine. The two sets of spiral grooves define a pair of intersecting fluid control paths that meet at the lower end of the body to create a dense mist.
