ABSTRACT:
An aerator for use on water faucets having a metal casing and a one-piece plastic insert that includes both the diaphragm for directing a large number of water jets in a downstream direction and a ledge for holding a screen to mix said water jets with air. The one-piece molded plastic insert is held in the casing due to compression between the downstream end of the faucet and an inturned ledge or lip at the downstream end of the metal casing. The one-piece insert defines air intake passageways passing along the inside wall of the casing and entering the mixing space between the diaphragm and the screen. The plastic material is soft enough so that the upper end of the one-piece plastic insert makes a substantial seal with the faucet. If some water does pass this seal, it enters the air intake passageways and passes out the downstream end of the casing. Slits are provided in the side wall of the insert to enhance the molding of the insert.
