Central Flow Path Patents (Class 239/448)
  • Patent number: 9855567
    Abstract: A water nozzle with a flow head is provided with at least two separate water supply devices that supply, in a controllable fashion, different water volume flows to the flow head. The flow head generates an annular jet from the different water volume flows. By controlling the water volume flows, alternatively a slim annular jet or a widened annular jet is generated by the flow head. A deflection element with a central outlet opening is provided, wherein the central outlet opening is arranged in a flow direction of the annular jet downstream of and spaced apart from the flow head. A deflection device surrounds the central outlet opening. A diameter of the central outlet opening is designed such that the slim annular jet is able to pass through the central outlet opening while the widened annular jet impacts on the deflection device surrounding the central outlet opening.

  • Patent number: 7000854
    Abstract: A spray head for a faucet or the like has a wand body defining a flow path from an inlet to first and second outlets. Diverter seats are provided so a face seal on a diverter spool can direct flow to the first or second outlet. The spool is positioned by a trigger acting on cam surfaces formed on a toggle. A spring biases the toggle to one of two stable states. Movement of the spool by the trigger causes the toggle to change states so subsequent actuation of the trigger causes the spool to move in the opposite direction. The wand body also has a pause button that reciprocates in a chamber that is part of the flow path. The chamber includes a valve seat and the pause button has a spool having a face seal that is engageable with the valve seat to shut off flow through the spray head. A return spring causes separation of the pause button's face seal upon release of pressure on the pause button.
