Abstract
A dual-levered faucet assembly which allows user to reduce water usage by 50% when needed while operating the faucet in habitual preferred manner of using swift single motion of hand. When any one lever is operated in this manner, the water outflow is 50% of a conventional single-levered faucet. When both levers are operated in this manner, water outflow is same as that of a conventional single-levered faucet.
Claims14
A faucet assembly, comprising:
- a body having at least one inlet for introduction of fluid into the faucet assembly and an outlet for releasing fluid;
- a pair of devices to operate the faucet assembly, said pair of devices being operable by a first method and, selectively, a second method;
- a fixed-plate being a flat plate having a bottom surface and a top surface, with said bottom surface having at least one inflow aperture, wherein each said inflow aperture bifurcates into two inflow apertures at said top surface for fluid communication, and wherein said top surface having two outflow apertures converging into one outflow aperture at said bottom surface for fluid communication;
- a pair of movable-plates, positioned sealingly over the top surface of said fixed-plate, such that rectilinear movement of said pair of movable-plates varies flow rate of at least one fluid, and that rotational movement of said pair of movable-plates varies ratio mixture of the fluids;
- a coupling mechanism comprising two parts, such that each said part receives activation from corresponding device of said pair of devices and engages corresponding movable-plate of said pair of movable-plates;
- a housing positioned securely inside the body such that said housing sealingly encases members selected from a group consisting of the fixed-plate, the pair of movable-plates and the coupling mechanism, and
- whereas in operation using the first method, said pair of devices operate independent of each other and wherein each device of said pair of devices activates corresponding part of said coupling mechanism, whereby said part of the coupling mechanism conveys rectilinear movement to corresponding movable-plate of said pair of movable-plates, and
- whereas in operation using the second method, said faucet assembly has a means to constrain said pair of devices to operate together, and said pair of devices activates said coupling mechanism, whereby said coupling mechanism conveys rotational movement to said pair of movable-plates.

A faucet assembly, comprising:
- a body having at least one inlet for introduction of fluid into the faucet assembly and an outlet for releasing fluid;
- a pair of levers to operate the faucet assembly, said pair of levers being operable about a first axis and, selectively, a second axis;
- a fixed-plate being a flat plate having a bottom surface and a top surface, with said bottom surface having at least one inflow aperture, wherein each said inflow aperture bifurcates into two inflow apertures at said top surface for fluid communication, and wherein said top surface having two outflow apertures converging into one outflow aperture at said bottom surface for fluid communication;
- a pair of movable-plates, positioned sealingly over the top surface of said fixed-plate, such that rectilinear movement of said pair of movable-plates varies flow rate of at least one fluid, and that rotational movement of said pair of movable-plates varies ratio mixture of the fluids;
- a coupling mechanism comprising two parts, wherein each part is connected to corresponding lever of said pair of levers and said part engages corresponding movable-plate of said pair of movable-plates;
- a housing positioned securely inside the body such that said housing sealingly encases members selected from a group consisting of the fixed-plate, the pair of movable-plates and the coupling mechanism, and
- whereas in operation about the first axis, said pair of levers move independent of each other, wherein each lever of said pair of levers activates corresponding part of said coupling mechanism, whereby said part of the coupling mechanism conveys rectilinear movement to corresponding movable-plate of said pair of movable-plates, and
- whereas in operation about the second axis, said faucet assembly has means to constrain said pair of levers to move together about the second axis and said pair of levers activates said coupling mechanism, whereby said coupling mechanism conveys rotational movement to said pair of movable-plates.
