Abstract
Faucets are disclosed which provide a gentle, gravity driven cascading flow of water. A mixing valve is positioned in a faucet body which permits exiting water to flow outside the mixing valve inside the faucet housing. The valve unit is thus partially submerged by the water that has passed through it. The pool of water helps to create a more gentle uniform flow of water. A flow regulator can be positioned in the fluid outlet of the valve.
Claims9
A faucet, comprising:
- a faucet body having a bore that is in communication with a fluid inlet and a spout;
- and
- a valve unit positioned in the bore for regulating fluid flow from the fluid inlet to the spout, the valve unit and the faucet body being constructed and arranged to allow fluid exiting the valve unit to flow between the outer periphery of the valve unit and the faucet body before flowing into the spout;
- wherein the valve unit is in the form of a cartridge positioned in a valve unit housing that allows fluid to pass out the valve unit housing and then rise outside of the valve unit between the valve unit housing and the faucet body;
- wherein the valve unit housing has a fluid outlet with a lateral passage for directing fluid against an inside wall of the valve unit housing before it exits the valve unit housing.
