  • Publication number: 20070278444
    Abstract: A wear resistant component for a faucet valve includes a substrate comprising a base material and a strengthening layer provided above the substrate in an amount sufficient to improve abrasion resistance of the substrate. The strengthening layer includes at least one material selected from the group consisting of tantalum, chromium, zirconium, and tungsten. The wear resistant component also includes a layer that includes amorphous diamond provided above the strengthening layer, the amorphous diamond having sp3 bonding of at least about 40%, a hardness of at least about 45 GPa, and an elastic modulus of at least about 400 GPa.

  • Publication number: 20070181843
    Abstract: A valve component for a faucet includes a substrate, a first layer of material provided above the substrate in an amount sufficient to improve abrasion resistance of the substrate, and a second layer of material provided above the first layer of material. The second layer of material includes amorphous diamond having sp3 bonding of at least about 40%, a hardness of at least about 45 GPa, and an elastic modulus of at least about 400 GPa.

  • Publication number: 20070029404
    Abstract: A sprinkler is disclosed for improved flow characteristics. The sprinkler has a sprinkler head rotatably supported for distributing water and defining a flow channel for directing water flow therethrough with reduced head loss. The flow channel has a smoothly tapered portion for receiving water and channeling the water towards an outlet in communication with a first nozzle for distributing the water. The flow channel with reduced head loss produces a greater throw distance at a lower trajectory with a lower flow rate and pressure. The flow channel may be formed within a flow channel member positioned within the sprinkler head. The flow channel member may cooperate with the sprinkler head to define a cavity allowing water to pass through the cavity from the flow channel for emission from a plurality of other nozzles.
