Abstract
A faucet control device comprising (a) a hollow sleeve member having one outlet and two, axially spaced and opposite each other, inlets capable of being connected with hot and cold water conduits, the latter having separate control handles, and (b) a piston slidable in the sleeve for movement between a first inserted position in which said inlets are blocked and a second retracted position in which said inlets communicate with said outlet, so that the flow can be regulated independently of the hot and cold water controls. As said piston moves between either of said positions the flow of water varies depending on the amount of its movement. Said outlet acting in this case as a flow passage, can be connected with a spout provided with a valve for selectively diverting the flow of water between two outlets for tub and shower use.
Claims2
Apparatus comprising a hollow sleeve member having hot and cold water inlets for connection to hot and cold water supplies, and one outlet, and piston means slidably mounted in said sleeve for movement between a first position in which said inlets communicate with said outlet, and a second position in which said inlets are blocked,
- said sleeve having a cylindrical bore,
- said inlets being axially located at different levels,
- said inlets being provided with oblong holes,
- said outlet being coaxial and coextensive with said bore,
- said piston means in its movement between the first and the second position gradually opening or closing the inlets to increase or reduce the rate of flow through said inlets to said outlet,
- said piston means comprising first and second axially spaced piston portions, confined for sealed slidable movement in said cylindrical bore,
- said piston portions provided with O-ring seals,
- said piston means comprising a stem on which said first and second piston portions are secured,
- said stem being of smaller diameter than said first and second piston portions,
- said stem having an inlet between said first and second piston portions and a central flow passage bored axially in said stem and communicating with said outlet.
