ABSTRACT:
An aerator, that includes jet-defining slots and jet-fragmenting surface therein, formed in molded plastic parts, is provided with both self-cleaning character by using a movable valve member and a flow-directing washer of shape-retaining character upstream thereof, and with a noise reduction feature obtained by providing on the movable valve member a centrally located conical projection that, in the non-flow condition, extends through and upstream of the flow directing washer.
