6. The spray assembly of claim 5 , wherein said lug has a hexagonal cross-section in a plane that is perpendicular to the axial direction.
7. The spray assembly of claim 5 , wherein said spray arm comprises an upper spray arm body mounted to a lower spray arm body in order to define the chamber therebetween, the upper spray arm body defining the opening and said lug mounted to the lower spray arm body.
8. The spray assembly of claim 1 , wherein the conduit of said bearing has an annular cross-section in a plane that is perpendicular to the axial direction.
9. The spray assembly of claim 1 , wherein said bracket has an outer surface and said spray arm has an outward surface that faces the outer surface of said bracket, the outer surface of said bracket spaced apart from the outward surface of said spray arm by less than about one inch.
10. The spray assembly of claim 1 , wherein said spray arm comprises an upper spray arm body mounted to a lower spray arm body in order to define the chamber, the upper spray arm body defining the opening and the lower spray arm body defining a plurality of spray ports for directing wash fluid out of the chamber.
11. A spray assembly for a dishwasher appliance, the spray assembly defining an axial direction and a radial direction, the spray assembly comprising:
a spray arm defining an opening and a chamber for receipt of wash fluid from the opening;
a bearing, said spray arm rotatably mounted to said bearing, said bearing comprising:
a conduit received within the opening of said spray arm;
a plurality of projections positioned on the conduit and projecting along the radial direction therefrom; and
a flange mounted to the conduit and projecting from the conduit along the radial direction, the flange being positioned within the chamber of said spray arm;
a bracket defining an aperture and a plurality of slots, the conduit of said hearing received within the aperture of said bracket and each projection of the plurality of projections of said bearing received within a respective one of the plurality of slots of said bracket; and
a support fixed to said bracket and extending away from said bracket along the axial direction, the support defining a notch that is configured for mounting the spray assembly to a dishwasher appliance.
12. The spray assembly of claim 11 , further comprising means for selectively rotating the conduit of said bearing within the aperture of said bracket with said spray arm.
13. The spray assembly of claim 12 , wherein said means for selectively rotating comprises:
a socket positioned within the chamber of said spray arm; and
a lug mounted to the conduit of said bearing and aligned with said socket along the axial direction, said lug receivable within said socket in order to enable rotation of the conduit of said bearing within the aperture of said bracket with said spray arm.
14. The spray assembly of claim 13 , wherein said lug has a hexagonal cross-section in a plane that is perpendicular to the axial direction.
15. The spray assembly of claim 13 , wherein said spray arm comprises an upper spray arm body mounted to a lower spray arm body in order to define the chamber therebetween, the upper spray arm body defining the opening and said socket mounted to the lower spray arm body.
16. The spray assembly of claim 12 , wherein said spray assembly defines an axial direction, wherein said means for selectively rotating comprises:
a socket mounted to the conduit of said bearing; and
a lug positioned within the chamber of said spray arm and aligned with said socket along the axial direction, said lug receivable within said socket in order to enable rotation of said bearing with said spray arm.
17. The spray assembly of claim 16 , wherein said lug has a hexagonal cross-section in a plane that is perpendicular to the axial direction.
