First Claim
Patent Images
1. A valve assembly for use with an electronic faucet, the valve assembly comprising:
- a valve housing having a cavity;
a magnetic field sensor supported by the valve housing; and
a valve member disposed within the cavity and including a magnet, the valve member being movable between a first position relative to the sensor to generate a first signal, and a second position relative to the sensor to generate a second signal, wherein the magnet is positioned further from the sensor when the valve member is in the second position than when the valve member is in the first position.

12. An electronic faucet assembly comprising:
-
a water inlet conduit;
a delivery spout;
a valve body in fluid communication with the water inlet conduit and the delivery spout;
a manual valve member supported by the valve body and configured to move between an open position and a closed position for controlling fluid flow from the water inlet conduit to the delivery spout;
a sensing element supported by the manual valve member and configured to move with the manual valve member;
a position sensor located in spaced relation to the sensing element and configured to detect the relative position of the sensing element and in response thereto provide a signal indicative of the position of the manual valve member;
an actuator driven valve in fluid communication with the manual valve member;
a proximity sensor having a detection zone, the proximity sensor being configured to generate a proximity signal when the proximity sensor detects the presence of an object within the detection zone; and
a controller in electrical communication with the position sensor, the actuator driven valve, and the proximity sensor, the controller being configured to deactivate the proximity sensor when the position sensor indicates that the manual valve member is in the closed position. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A valve assembly for use with an electronic faucet, the valve assembly comprising:
-
a valve housing having a cavity;
a movable valve member disposed within the cavity, the valve member including a ball having a hot water inlet, a cold water inlet, a mixed water outlet and a connecting passageway providing fluid communication between the hot water inlet, the cold water inlet, and the mixed water outlet;
a holder supported within the connecting passageway of the ball; and
a magnet operably coupled to the holder. - View Dependent Claims (20, 21, 22, 23, 24)
