Faucet with gear linkage mechanism

A dual control faucet system comprising:

• a cold water control comprising a cold water control system housed within the cold water control, wherein the cold water control system comprises a first bevel gear;
• a hot water control comprising a hot water control system housed within the hot water control, wherein the hot water control system comprises a second bevel gear;
• a faucet body;
• and
• a valve assembly comprising a third bevel gear coupled to one end of a cold water spindle, a first rotatable disk and a first stationary disk positioned at another end of the cold water spindle, a fourth bevel gear coupled to one end of a hot water spindle, and a second rotatable disk and a second stationary disk positioned at another end of the hot water spindle,
• wherein the first bevel gear is meshed with the third bevel gear and the second bevel gear is meshed with the fourth bevel gear,
• wherein, when the cold water control receives an input from a user, the cold water control causes the first bevel gear to rotate, causing the third bevel gear to rotate, such that the cold water spindle rotates the first rotatable disk relative to the first stationary disk in an opening direction or in a closing direction to control a flow of cold water from a cold water supply and into a cold water cartridge of the valve assembly, and
• wherein, when the hot water control receives an input from a user, the hot water control causes the second bevel gear to rotate, causing the fourth bevel gear to rotate, such that the hot water spindle rotates the second rotatable disk relative to the second stationary disk in an opening direction or in a closing direction to control a flow of hot water from a hot water supply and into a hot water cartridge of the valve assembly.
