1. A spray head for a fluid distribution system comprising: a spray head base defining a fluid inlet passage;a spray head body connected to the spray head base;a first deflector extending outward from the spray head body and having a first inner surface;a second deflector extending outward from the spray head base and having a second inner surface, the first and second inner surfaces disposed in opposed, spaced relation defining a fluid outlet passage;a piston disposed in a chamber of the spray head body, the piston defining a variable orifice to control flow from the fluid inlet passage to the fluid outlet passage; anda diverter plate disposed on the second inner surface and within the fluid outlet passage defined by the first deflector and the second deflector, the diverter plate having a first end, a second end, and an inner deflector surface extending between the first and second ends opposing the variable orifice. 2. The spray head of claim 1, wherein the inner deflector surface has an inner curvature between the first and second ends. 3. The spray head of claim 2, wherein the diverter plate has an outer surface having an outer curvature equal to the inner curvature. 4. The spray head of claim 3, wherein the diverter plate has a top planar surface connecting the inner and outer deflector surfaces. 5. The spray head of claim 1, wherein the diverter plate has a wedge shaped cross-section. 6. The spray head of claim 1, wherein the diverter plate is integral with the second deflector and spray head base. 7. The spray head of claim 1, wherein the fluid outlet passage is disposed along a plane perpendicular to the fluid inlet passage, the piston having a dam portion that extends outwardly in an arc from a piston axis, the dam portion positioned between two side walls of the spray head body, wherein a lower surface of the dam portion, the two side walls, and the second inner surface of the second deflector define the variable orifice. 8. The spray head of claim 7, wherein a length of the inner deflector surface is coextensive with a length of the variable orifice between the two side walls. 9. The spray head of claim 7, wherein the dam includes a dam outer surface having an outer surface curvature, the inner deflector surface having a deflector curvature equal to the outer surface curvature. 10. The spray head of claim 9, further including a gap provided between the dam outer surface and the inner deflector surface that provides unrestricted flow between the fluid inlet passage and the fluid outlet passage as the piston moves toward an open position. 11. The spray head of claim 10, wherein the gap is between about 2 mm and about 10 mm. 12. The spray head of claim 10, wherein the gap is 10 mm. 13. The spray head of claim 1, wherein a height of the inner deflector surface is between 2 mm and 10 mm. 14. The spray head of claim 1, wherein a height of the inner deflector surface is about 5 mm and a maximum opening height of the variable orifice is about 19 mm. 15. A spray head for a fluid distribution system comprising: a spray head base defining a fluid inlet passage;a spray head body connected to the spray head base;a first deflector extending outward from the spray head body and having a first inner surface;a second deflector extending outward from the spray head base and having a second inner surface, the first and second inner surfaces disposed in opposed, spaced relation defining an elongated fluid outlet passage;a piston disposed in a chamber of the spray head body for controlled access between the inlet and outlet passages and defining a variable orifice;a diverter plate disposed on the second inner surface, the diverter plate having an inner deflector surface opposing the variable orifice; andan internal diverter joined to the piston, wherein the internal diverter is disposed within the inlet passage when the variable orifice is in a closed position. 16. The spray head of claim 15, wherein the fluid inlet passage is disposed perpendicular to the fluid outlet passage, the fluid inlet passage including a circular opening, the internal diverter having an elongated bottom surface aligned with a diameter of the circular opening transverse to the fluid outlet passage. 17. The spray head of claim 15, wherein the internal diverter has a wedge-shaped cross-section. 18. The spray head of claim 15, wherein the inner deflector surface has an inner curvature between the first and second ends. 19. A spray head for a fluid distribution system comprising: a spray head base defining a fluid inlet passage;a spray head body connected to the spray head base;a first deflector extending outward from the spray head body and having a first inner surface;a second deflector extending outward from the spray head base and having a second inner surface, the first and second inner surfaces disposed in opposed, spaced relation defining a fluid outlet passage, the fluid outlet passage disposed along a plane transverse to the fluid inlet passage;a piston disposed in a chamber of the spray head body, the piston defining a curved, variable-height orifice to control flow between the fluid inlet and fluid outlet passages; anda diverter plate disposed on the second inner surface, the diverter plate having a first end, a second end, and an inner deflector surface opposing the variable height-orifice across a gap, a curvature of the inner deflector surface corresponding to a curvature of the variable-height orifice. 20. The spray head of claim 19, further including an internal diverter joined to the piston, the internal diverter having an elongated bottom surface disposed across the fluid inlet passage and transverse to a centerline of the fluid outlet passage. 21. The spray head of claim 20, wherein the internal diverter has a wedge-shaped cross-section, one corner of the wedge being joined to the piston.
