Water faucet with joystick cartridge

Abstract

The invention provides a water faucet including a novel joystick mixing cartridge with internal structures that provide a direct path for water to be discharged from the faucet. The faucet includes a main body portion, a discharge segment and a handle that an operator actuates to deliver water at a desired temperature through the discharge segment. The cartridge includes a housing defining an internal chamber and a lower disk positioned within the chamber. The lower disk has a cold water inlet, a hot water inlet and a mixed water outlet. An intermediate disk is positioned adjacent the lower disk and includes a recessed mixing cavity extending inward from a lowermost wall. The intermediate disk includes a dual lobe sealing element that extends radially inward from the lowermost wall to provide the mixing cavity with an arcuate configuration. An upper disk is positioned adjacent the intermediate disk and a seat is positioned adjacent the upper disk within the chamber. A joystick extends through the seat and the housing for connection with a faucet handle. When an operator actuates the handle and joystick, the intermediate disk is moved within the chamber whereby the position of the mixing cavity relative to the hot and cold water inlets and the water outlet is varied to deliver water at the desired temperature.
