Water faucet with joystick cartridge
First Claim
1. A water faucet comprising:
- a faucet having 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;
a cartridge assembly positioned within the main body portion, the cartridge assembly including;
a housing defining an internal chamber;
a lower disk positioned within the chamber, the lower disk having a cold water inlet, a hot water inlet and a mixed water outlet;
an intermediate disk positioned adjacent the lower disk within the chamber, the intermediate disk having a recessed mixing cavity extending inward from a lowermost wall that slidingly contacts the lower disk, the intermediate disk further having a dual lobe sealing element that extends radially inward from the lowermost wall to provide the mixing cavity with an arcuate configuration, the intermediate disk having a diameter that is less than a diameter of the lower disk;
an upper disk positioned adjacent the intermediate disk within the chamber, the upper disk having a central aperture and at least one engaging member that operably couples the upper disk to the intermediate disk;
a seat positioned adjacent the upper disk within the chamber, the seat having a central opening;
a joystick having an shaft extending through the seat opening and through the housing for connection with handle, the joystick further having a depending actuator that is received in the upper disk aperture to operably connect the joystick to the upper disk; and
,wherein actuation of the handle and joystick results in movement of the upper disk and the intermediate disk whereby the position of the mixing cavity relative to the hot and cold water inlets and the water outlet is varied.

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.

10. A water faucet comprising:
-
a faucet body having a main body portion, a discharge segment and a handle that an operator actuates to deliver hot, warm or cold water at a desired volume through the discharge segment; a cartridge assembly positioned within the main body portion, the cartridge assembly including; a housing defining an internal chamber; a lower disk positioned within the chamber and having an X axis and Y axis that define four quadrants wherein the first and fourth quadrants are directed away from the discharge segment of the faucet body, and the second and third quadrants are directed towards the discharge segment, the lower disk having a cold water inlet in the first quadrant, a hot water inlet in the fourth quadrant and a water outlet hole in the second and third quadrants; an intermediate disk slidingly positioned on the lower disk within the chamber, the intermediate disk having an arcuate recessed mixing cavity and a sealing element that extends radially inward from an outermost wall of the disk and into the mixing cavity, wherein the intermediate disk has a diameter less than a diameter of the lower disk whereby the intermediate disk is slidable on the lower disk within the chamber; an upper disk having a central aperture and at least one engaging member that operably couples the upper disk to the intermediate disk; a joystick having a shaft extending through the housing for connection with the handle, the joystick further having a depending actuator that is received in the upper disk aperture to operably connect the joystick to the upper disk and the intermediate disk; and
,wherein actuation of the handle results in movement of the intermediate disk on the lower disk whereby the position of the mixing cavity and the sealing element relative to the hot and cold water inlets and the water outlet is varied, and wherein water at desired temperature and volume is discharged through the water outlet of the lower disk and the discharge segment of the faucet body. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
