Abstract
An adjustable arc irrigation spray nozzle can include one or more features including a dual orifice, a multi-trajectory ramp, radial ribs, an impedance wall, and/or a variable orifice.
Claims20
An adjustable spray nozzle comprising:
- a lower member and an upper member rotatably coupled to the lower member to vary a length of an arc opening for water to exit the nozzle, the lower member and the upper member defining a path for the water to flow from a passage within the lower member to an exit of the nozzle, the path including an upstream orifice located downstream from the passage, a manifold located downstream of the upstream orifice, and a downstream orifice located downstream of the manifold, the upstream orifice defining a first gap, the downstream orifice defining a second gap, and the manifold defining a third gap, the third gap being sized greater than the first gap to cause a sudden expansion and drop in pressure of the water exiting the first gap and entering the manifold,
- wherein varying the length of the arc opening by rotating the upper member relative to the lower member varies both a length of the first gap and a length of the second gap.
An adjustable spray nozzle comprising:
- a lower member and an upper member rotatably coupled to the lower member to vary a length of an arc opening for water to exit the nozzle, the lower member and the upper member defining a path for the water to flow from a passage within the lower member to an exit of the nozzle, the path including a plurality of orifices and a manifold, the manifold being disposed between at least two orifices of the plurality of orifices, at least one of the plurality of orifices defining a gap upstream of the manifold, the gap being sized smaller than the manifold to cause a sudden expansion and drop in pressure of the water exiting the gap and entering the manifold,
- wherein another of the plurality of orifices defines a second gap, and wherein varying the length of the arc opening varies both a length of the gap and a length of the second gap.
An adjustable spray nozzle comprising:
- a lower member having an inlet;
- an upper member rotatably coupled to the lower member to vary a length of an arc opening for water to exit the nozzle;
- a flow path defined by the lower member and the upper member for the water to flow from the inlet to the arc opening;
- an upstream orifice disposed along the flow path and downstream from the inlet, the upstream orifice defining a first gap;
- a downstream orifice disposed along the flow path and downstream from the upstream orifice, the downstream orifice defining a second gap;
- and
- a manifold disposed along the flow path and between the upstream orifice and the downstream orifice, the manifold defining a third gap that is sized greater than the first gap to cause a sudden expansion and drop in pressure of the water exiting the first gap and entering the manifold,
- wherein varying the length of the arc opening varies both a length of the first gap and a length of the second gap.
