1. A spray head comprising:
- a body including a fluid port configured to be coupled to a water supply; and
a cartridge received within the body, the cartridge including an inlet in fluid communication with the fluid port, a first outlet in fluid communication with the inlet and configured to produce from the spray head a water stream, a second outlet having a longitudinal axis and a fluid contact surface extending around the longitudinal axis and in fluid communication with the inlet, a whirl member configured to impart rotational movement about the longitudinal axis to water passing from the inlet to the second outlet, such that centrifugal force causes the water moving toward the second outlet to follow the fluid contact surface, and a reflector positioned intermediate the whirl member and the fluid contact surface to reverse the direction of water supplied from the whirl member, the direction of water again reversed from the reflector to the fluid contact surface to assist in providing uniform water flow to the fluid contact surface, wherein a continuous shield of water extends outwardly from the spray head in a sheet-like layer around the water stream and is spaced apart from the water stream, the water stream produced from the spray head by the first outlet having a substantially laminar flow.

13. A spray head comprising:
-
a body including a fluid port; a mount removably received within the body; a flow straightening member operably coupled to the mount and in fluid communication with the fluid port, the flow straightening member being configured to assist in removing turbulence from water; a nozzle operably coupled to the straightening member and including an outlet orifice configured to produce from the spray head a center water stream; and a whirl member operably coupled to the mount and extending around the flow straightening member, the whirl member including a body having a plurality of slots, a fluid passageway defined between the body of the whirl member and the flow strengthening member and in fluid communication with the fluid port, wherein the slots of the whirl member are configured to impart rotational movement to water supplied to a serpentine passageway between the whirl member and a fluid contact surface, such that water from the whirl member follows the fluid contact surface for producing from the spray head a continuous shield of water extending around the center water stream and spaced apart from the center water stream. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method of generating a water pattern comprising the steps of:
-
supplying water to a cartridge assembly having a first outlet and a second outlet; producing from the first outlet a center water stream having a substantially laminar flow; and producing from the second outlet an outer continuous shield of water extending outwardly in a sheet-like layer around the center water stream and spaced apart from the center water stream, including the steps of imparting rotational movement to the water, providing substantially uniform flow to the water by reversing a plurality of times the direction of water flow, and causing the rotating water to follow a fluid contact surface within the second outlet. - View Dependent Claims (22, 23)

24. A method of generating a water pattern with a water delivery device comprising the steps of:
-
dividing a supply of water provided to the water delivery device into at least a first portion and a second portion; and supplying from an exterior of the water delivery device a stream of water based on the first portion and a continuous shield of water based on the second portion, the stream of water having a substantially laminar flow and the continuous shield of water rotating about a longitudinal axis of the stream of water and spaced apart from the stream of water, the continuous shield of water having a substantially uniform flow by reversing a plurality of times the direction of flow. - View Dependent Claims (25, 26, 27, 28)
