Abstract
A sprinkler body for a rotating sprinkler includes a base securable to a source of water under pressure, a plurality of support struts connected to and extending from the base, and a deflector plate support connected to the plurality of support struts and disposed spaced from the base by the support struts. At least one of the plurality of support struts is wedge-shaped with an inward-facing apex. The support struts are configured to create a void in the water spray pattern away from a center pivot pipe and to direct the water spray downward to limit the effect of wind on the spray pattern.
Claims15
A sprinkler body for a rotating sprinkler, the sprinkler body comprising:
- a base securable to a source of water under pressure, the base having a central axis;
- a plurality of support struts connected to and extending from the base;
- and
- a deflector plate support connected to the plurality of support struts and disposed spaced from the base by the support struts,
- wherein at least one of the plurality of support struts is wedge-shaped with an apex facing the central axis that is oriented to create a void in a water spray pattern, and
- wherein the at least one of the plurality of support struts comprises a plurality of deflection fins that are spaced from one another and positioned along a length and across a middle of the at least one of the plurality of support struts and that protrude from an inward-facing surface thereof, wherein the deflection fins are angled downward in a direction radially outward from the central axis, and wherein water that impacts the support struts is directed downward by the deflection fins.
A sprinkler body for a rotating sprinkler, the sprinkler body comprising:
- a base securable to a source of water under pressure, the base having a central axis;
- a pair of support struts connected to and extending from the base, the support struts being spaced 180 degrees apart;
- and
- a deflector plate support connected to the pair of support struts and disposed spaced from the base by the support struts,
- wherein each of the pair of support struts is wedge-shaped with an apex facing the central axis and two inward-facing surfaces extending outward from the apex that are oriented to create a void in a water spray pattern, each of the support struts comprising a plurality of deflection fins that are spaced from one another and positioned along a length and across a middle of the support struts and that protrude from each of the two inward-facing surfaces, and wherein the deflection fins are angled downward in a radially outward direction, wherein water that impacts the support struts is directed downward by the deflection fins.
