1. A faucet comprising:
- a delivery spout including an outlet; and
a pull-out spray head fluidly coupled to a flexible water conduit extending through the delivery spout, and removably coupled to the outlet of the delivery spout, the spray head includinga valve housing having an inlet, an outlet, and a compartment positioned intermediate, and in fluid communication with, the inlet and the outlet,a volume control movably supported within the compartment for providing continuous variable adjustment of fluid flow rate between the inlet and the outlet from a low flow to a high flow, the volume control configured to be set and maintained in a first position relative to the valve housing to provide the low flow, in a second position relative to the valve housing to provide the high flow, and in a plurality of positions intermediate the first position and the second position to provide fluid flow rates intermediate the low flow and the high flow,the volume control including a rotatable valve member having at least one opening in fluid communication with the inlet and in selective communication with the outlet,the valve member including a rotatable valve plate having at least one opening,the outlet including a first outlet and a second outlet spaced from the first outlet,wherein rotation of the valve plate such that the at least one opening is in fluid communication with the first outlet defines a stream mode of operation, androtation of the valve plate such that the at least one opening is in fluid communication with the second outlet defines a spray mode of operation.

Abstract
A faucet spray head having a volume control mechanism allowing the user to adjust the flow of water through the spray head from a full-spray to full-stream and to a paused flow and flow levels therebetween. The volume control mechanism illustratively includes a spring-activated safety mechanism that prevents the user from inadvertently leaving the faucet head in an off position, thereby preventing the mixing or backing up of hot water into the cold water supply.

1. A faucet comprising:
-
a delivery spout including an outlet; and a pull-out spray head fluidly coupled to a flexible water conduit extending through the delivery spout, and removably coupled to the outlet of the delivery spout, the spray head including a valve housing having an inlet, an outlet, and a compartment positioned intermediate, and in fluid communication with, the inlet and the outlet, a volume control movably supported within the compartment for providing continuous variable adjustment of fluid flow rate between the inlet and the outlet from a low flow to a high flow, the volume control configured to be set and maintained in a first position relative to the valve housing to provide the low flow, in a second position relative to the valve housing to provide the high flow, and in a plurality of positions intermediate the first position and the second position to provide fluid flow rates intermediate the low flow and the high flow, the volume control including a rotatable valve member having at least one opening in fluid communication with the inlet and in selective communication with the outlet, the valve member including a rotatable valve plate having at least one opening, the outlet including a first outlet and a second outlet spaced from the first outlet, wherein rotation of the valve plate such that the at least one opening is in fluid communication with the first outlet defines a stream mode of operation, and rotation of the valve plate such that the at least one opening is in fluid communication with the second outlet defines a spray mode of operation. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A spray head for use with a faucet, the spray head comprising:
-
a housing including an inlet, a first outlet, and a second outlet, wherein fluid flow through the first outlet defines a first mode of operation, and fluid flow through the second outlet defines a second mode of operation; a control interface supported by the housing, wherein the same actuating movement of the control interface simultaneously selects at least one of the first mode of operation through the first outlet and the second mode of operation through the second outlet, and the rate of fluid flow from a low flow to a high flow through at least one of the first and second outlets in the selected mode of operation; a valve member operably coupled to the control interface and supported within the housing, the valve member including at least one opening in fluid communication with the inlet and in selective communication with the first and second outlets; and wherein rotation of the valve member to a first angular position causes the at least one opening to be in fluid communication with the first outlet for defining the first mode of operation, rotation of the valve member to a second angular position beyond the first angular position causes the at least one opening to be in fluid communication with the second outlet for defining the second mode of operation, and the rate of fluid flow varies as the valve member is rotated from the first angular position to the second angular position. - View Dependent Claims (10, 11, 12, 13, 14, 15, 23, 24, 25)

16. A spray head for use with a faucet, the spray head comprising:
-
a housing including an inlet, a first outlet, a second outlet, and a compartment in fluid communication with the inlet and the first and second outlets, wherein fluid flow through the first outlet defines a spray mode of operation, and fluid flow through the second outlet defines a stream mode of operation; a valve member movably supported within the compartment upstream from the first and second outlets, the valve member including a rotatable valve plate having at least one opening alignable with the first outlet in a first angular position and alignable with the second outlet in a second angular position, such that rotation of the valve plate intermediate the first and second angular positions further controls the flow rate of fluid from the inlet to at least one of the first and second outlets; and a user interface operably coupled to the valve member and supported for rotation relative to the housing, wherein rotation of the user interface causes rotation of the valve plate to adjust the flow rate of fluid supplied to the first outlet in the spray mode of operation and to the second outlet in the stream mode of operation. - View Dependent Claims (17, 18, 19, 20, 26)

21. A spray head for use with a faucet, the spray head comprising:
-
a housing including an inlet, a first outlet, a second outlet, and a compartment in fluid communication with the inlet and the first and second outlets; a first valve seat operably coupled to the first outlet; a second valve seat operably coupled to the second outlet; a valve plate positioned upstream of the first and second outlets of the housing, the valve plate configured to sealingly engage the first and second valve seats and rotatably supported within the compartment, the valve plate including at least one opening in fluid communication with the inlet and in selective fluid communication with the first and second outlets based upon the rotational position of the valve member; a rotatable stem operably coupled to the valve plate and extending in a direction outwardly from the housing; a rotatable knob operably coupled to the stem; and a spray face fluidly coupled to the housing and including a stream outlet in fluid communication with the second outlet of the housing and a plurality of spray outlets in fluid communication with the first outlet of the housing and surrounding the stream outlet, wherein a spray mode of operation is defined when the valve plate is rotated to a first angular position such that the at least one opening is in fluid communication with the first outlet of the housing and a stream mode of operation is defined when the valve plate is rotated to a second angular position such that the at least one opening is in fluid communication with the second outlet of the housing. - View Dependent Claims (27, 28, 29)
