ABSTRACT:
In a stream-controlling device for faucets, water from the faucet passes through a first flow-restricting orifice in a circular flow restrictor mounted in a casing secured to the faucet, the restrictor having a conical wall portion sloping downwardly and inwardly toward the orifice. From the latter water enters a chamber between the restrictor and the casing's bottom wall, the latter having opposite the orifice a recess with a conical surface which deflects the water radially outward through an annular second flow-restricting orifice formed by the bottom wall and the lower end of the restrictor's conical wall. From this second orifice, which has a larger throughflow area than the first orifice, water enters an annular subchamber having a substantially enlarged volume due to the restrictor's conical wall. The water is then divided so that part of it discharges through a radially inner set of holes in the bottom wall and the remainder through an outer set of holes, these holes collectively constituting a third flow-restricting orifice having a larger throughflow area than the second orifice.
