Abstract: A side spray diverter valve with anti-siphoning and flow regulation of the water diverted to the spray head. A ported valve plunger sliding in a sleeve admits water from the inlet to the spout in one position while a lower O-ring seals the spray outlet. In the other position, the sleeve has axially directed ports which screen and trap particulates in the water over a predetermined size. The flow rate of screened water to the spray is regulated by the lower O-ring pressing against grooves in the wall of the sleeve.

Abstract: A water spout end device for producing laminar flow of the water emitted therefrom comprising a generally cylindrical housing containing a cylindrical plastic component formed with a plurality of annular passages divided by annular spoke-like walls and characterized in that the plastic component is molded from ingredients including an anti-microbial agent.

Abstract: Coupler/diverter has housing with an aerator at the bottom and an inner barrel having rotary valving stem serving to distribute supply water, brine and overflow from RO filter. Depending on the setting, the stem permits flow through the housing to issue in the usual aerated stream. At this setting it also shuts off all other flow for decoupling. In diverting setting it sends supply to filter, shuttles return brine flush to the outside of the housing and lets reservoir overflow pass through the aerator. In a working setting the stem also can control volume of brine return to a varying degree to optimize the operation of the RO filter.
