ABSTRACT:
A spray aerator essentially of simple plastic parts having a swivel faucet attachment, a water conduit pipe, lateral openings in the pipe wall above its closed lower end, a spray housing slidable on the pipe, first and second housing inserts within the spray housing and slidable on the pipe, a flanged flexible snap retainer having downwardly depending legs and snapped over the lower pipe end into a groove to retain the spray housing and housing inserts on the pipe, a spray insert snapped over a ledge at the lower end of the spray housing, the spray insert having outer spray holes and an inner cylindrical tube for an aerator housing, an aerator assembly mounted in the aerator housing and supporting the first housing insert thereabove, and the snap mounting of the spray insert and snap retainer being the only means holding the spray aerator assembled and retained in the conduit pipe. In the spray mode, water flows through the pipe lateral openings to a first chamber between the second housing insert and conduit pipe, then to a second chamber between the spray housing wall and first housing insert, then out the spray holes in the pray insert. In the aeration mode, water flows through the insert, then out through the aerator assembly. The snap retainer provides two stops for the vertically displaced spray mode and aeration mode, respectively. Beveled surfaces on the snap retainer and a collapsible notch in the lower pipe end facilitate snapping the snap retainer over the lower pipe end. Sealing rings are provided in the spray aerator at separate points. A very simple and fast assembly sequence is provided by the above construction.
