Modulated stream pattern spray head

A spray head for connection to a faucet for expelling water, comprising:

• a spray head housing comprising an inlet, an outlet, and an intermediate section positioned between and in fluid communication with the inlet and the outlet;
• a movable pathway control stem attached to a pathway control seal, the pathway control seal having an inlet configured to receive a water flow and a passage configured to allow the water flow to exit the pathway control seal;
• a flow pathway disk assembly comprising:
• a first opening corresponding with an aerated stream flow path and a shower spray flow path;
• a second opening corresponding with a cone stream flow path;
• and
• a third opening corresponding with a straight beam stream flow path;
• a first control for selection between a shower spray mode for expelling a shower spray of water and a modulated stream mode for expelling a stream of water;
• a second control for modulating between patterns of the stream of water when in the modulated stream mode, the second control configured to receive an actuation force from a user, wherein the actuation force causes the second control to drive movement of the pathway control stem and the pathway control seal to:
• a first position where the passage of the pathway control seal is aligned with the first opening in the flow pathway disk assembly;
• a second position where the passage of the pathway control seal is aligned with the second opening in the flow pathway disk assembly;
• or
• a third position where the passage of the pathway control seal is aligned with the third opening in the flow pathway disk assembly;
• a central manifold positioned between the flow pathway disk assembly and a nozzle assembly, the central manifold comprising:
• a first port for receiving the water flow via the first opening in the flow pathway disk assembly;
• a second port for receiving the water flow via the second opening in the flow pathway disk assembly;
• a third port for receiving the water flow via the third opening in the flow pathway disk assembly;
• a fourth port for receiving the water flow received in the first port when the first control is in an unbiased position;
• a diverter chamber configured to receive a piston connected to the first control, wherein actuation of the first control to a biased position causes the piston to close the fourth port and open a fifth port;
• and
• the fifth port configured to receive the water flow received in the first port when the first control is in the biased position;
• and
• the nozzle assembly comprising:
• a swirl nozzle for producing a cone stream as the water flow received via the second port in the central manifold exits the outlet of the spray head;
• a nozzle for producing a straight beam stream as the water flow received via the third port in the central manifold exits the outlet of the spray head;
• an aerator subassembly for producing an aerated stream as the water flow received via the fourth port in the central manifold exits the outlet of the spray head;
• and
• a spray outlet for producing a shower spray as the water flow received via the fifth port in the central manifold exits the outlet of the spray head.
