A spray and aerator faucet appliance is provided by a construction wherein the selection of water discharge is effected by merely rotating the water discharge head portion of the appliance until the desired water discharge from the appliance appears. Selectivity is achieved by providing two abutting internal parts, each with a flow passageway located eccentric of the axis of the appliance, with seal means for the eccentric flow passageway provided between the abutting parts, for permitting selection either of flow only through the eccentric flow passageways when aligned, or no flow through the eccentric passageways when not aligned, thereby permitting discharge of flow through an alternate flow path. Each of the two abutting internal parts is locked internally of the appliance to one of the two portions of the appliance between which relative rotation is effected by rotating the discharge head. All parts of the appliance, except for the seals and screens, are inexpensively executed in plastic.

In a spray-or-aerator appliance that includes an upstream axially elongated adapter means through which flowing liquid is introduced into the appliance from a source under pressure, and a downstream discharge head shaped and arranged to provide, at the discharge end thereof, two concentric flow passageway means including a relatively large central passageway with an aerator construction therein, and an outer annulus of circumferentially spaced, smaller, spray apertures; the improvement comprising, in combination: the upstream adapter means having relatively non-rotatable character and being shaped to provide adjacent its downstream end an internal, non-circular, socket means surrounding a central flow passageway; the discharge head being axially positioned upon the downstream end of said adapter means and being rotatable relative to said adapter means, the discharge head providing therein an upstream facing central disc with an eccentric aperture therein, said upstream facing disc being operative to substantially close off liquid flow to the large central passageway except through said eccentric aperture; an internal diverter member positioned between said upstream adapter means and the discharge head, said diverter member being shaped to provide: (a) an upstream non-circular means for interfitting engagement with the non-circular socket means of the upstream adapter means; (b) an eccentrically apertured, central disc adapted for abutment with a portion of the central disc of the discharge head; and (c) laterally apertured flow means positioned in a flow path between said eccentrically apertured central disc of the diverter member and the circumferentially spaced spray apertures of the discharge head; and compression seal means positioned between portions of the central discs of the internal diverter and of the discharge head, and surrounding the eccentric aperture in the central disc of the discharge head, for isolating downstream liquid flow in the discharge head either through only the pair of aligned eccentric apertures of the two discs, so that said flow will be directed through the large central passageway of the discharge head, or through an alternate flow path, that includes said laterally apertured flow means of the diverter member when the eccentric apertures are not aligned, that communicates with the outer annulus of smaller spray apertures in the discharge head.
