Abstract
Within a cylindrical barrel to be secured to the water faucet are a basket surrounding a mixing chamber, a diffuser overlying the mixing chamber and forming a diffusing chamber, having peripheral openings for flow of water to the mixing chamber, and a flow restrictor disc having a control opening for admitting water from said faucet to the diffusing chamber, the diffuser having resilient detents allowing the disc to be snapped into position on a seat of the diffuser where the disc is releasably retained by the detents. Preferably, a ring surrounds and supports the diffuser and forms therewith a passage for flow of water from the diffuser openings to the mixing chamber, the ring being supported on part of the basket.
