An irrigation sprinkler spray nozzle is provided that includes a first deflector surface defining a first configuration to project a fluid spray having a first distribution pattern, and a second deflector surface defining a second configuration to project a second fluid spray having a second, different distribution pattern. To select the fluid spray, the nozzle further includes a selector having a first position to select the first deflector surface and a second position to select the second deflector surface.

What is claimed is: 1. A spray nozzle assembly comprising: a base configured to communicate with a supply of fluid; a nozzle coupled to the base, the nozzle defining a first fluid passage for the passage of fluid; a first deflector surface to deflect fluid received from the nozzle with a first spray pattern, the first deflector surface having a first position in fluid communication with the first fluid passage and a second position not in fluid communication with the first fluid passage; a flow-control device between the nozzle and the first deflector surface, the flow-control device defining a second fluid passage configured for fluid communication with the first fluid passage; the first fluid passage having a first diameter and the second fluid passage having a second diameter, the first diameter being smaller than the second diameter such that a pressure drop at an interface between the nozzle and the flow-control device is formed from a fluid flowing therethrough to minimize fluid leakage at the interface; and wherein the flow-control device includes a second deflector surface to deflect fluid received from the nozzle with a second spray pattern, the second deflector surface having a third position in fluid communication with the first fluid passage and a fourth position not in fluid communication with the first fluid passage. 2. The spray nozzle assembly of claim 1, wherein the second deflector surface extends radially from the second fluid passage to an outer edge of the flow-control device. 3. The spray nozzle assembly of claim 2, wherein the second deflector surface is a recess defined by an upper wall and facing side walls at an underside of the flow-control device, the upper wall being curved to focus a fluid spray close to the spray nozzle assembly. 4. The spray nozzle assembly of claim 1, wherein an outer edge of the second fluid passage defines an occlusion extending inwardly thereto from the second deflector surface, the occlusion redirecting a portion of the fluid flowing through the second fluid passage into the second deflector surface.
