Abstract:
A pressure regulator includes a housing having an inlet cap with an inlet flow passage and an outlet cap with an outlet flow passage. A plunger is reciprocally mounted in the housing. A stationary regulator valve seat is disposed between the inlet flow passage and an inlet to the plunger. A drain check shuttle is disposed in the inlet cap and positioned downstream of the regulator valve seat to prevent water from draining out of the regulator when an inlet water pressure is below a predetermined threshold.
Abstract:
A sprinkler module is cooperable with a sprinkler nozzle unit supporting a sprinkler nozzle to define a sprinkler configuration. The sprinkler module includes a cage attachable to the sprinkler nozzle unit and including a pair of struts, a cap connected to the cage via the pair of struts, and a deflector plate cooperable with the sprinkler nozzle and rotatably secured between the cap and the cage. The deflector plate includes a hub extending through the cap. A plate gear with gear teeth is secured to the hub and is rotatable with the deflector plate, and a cover assembly is connected to the cap. The cover assembly includes a brake gear coupled with a brake assembly, where the brake gear is disposed in a path of the gear teeth.
Abstract:
A sprinkler nozzle is configured for a sprinkler positioned at a distal end of a center pivot irrigation system. The sprinkler nozzle includes a connection part securable to the sprinkler, and a nozzle opening downstream of the connection part. A nozzle opening downstream of the connection part is part-toroidal shaped and partially blocked or skewed to control water flow to portions of the deflector plate according to a desired wetted area. The part-toroidal shape spans an arc less than 360 degrees. The nozzle enables a custom designed water application to complement the other sprinklers that are on the pivot and can be shaped to also apply water a distance beyond the end of the pivot pipe to match the application rate of the sprinklers along the pivot pipe.
Abstract:
A gooseneck pipe includes a first pipe half having a first radiused centerline curve, and a second pipe half fixed to the first pipe half and having a second radiused centerline curve. The first and second pipe halves define a flow path. Cross-sectional diameters of the first and second pipe halves vary along the flow path. The varying diameters of the first and second pipe halves serve to mitigate pressure losses due in part to Dean vortices or secondary flow patterns in the flow path when a fluid is turned in the gooseneck pipe.
Abstract:
A pressure regulator (10, 90) including: a housing (12, 14, 100) including an inlet flow passage (24, 106) and an outlet flow passage (26); a plunger (30, 92) reciprocally mounted in the housing and including a plunger flow passage (34) having an axis (36) offset from an axis (42) of the inlet flow passage; and a stationary valve seat (32, 102) fixed to the housing and positioned between the inlet flow passage and an inlet to the flow passage of the plunger, wherein the valve seat is configured to receive and abut the inlet to the flow passage of the plunger.
Abstract:
A sprinkler assembly includes a sprinkler body with a water flow passage connected to a water source. The sprinkler body includes a recess. A nozzle insert is received in the recess and is positionable in the recess in multiple positions. The nozzle insert includes a nozzle bore extending therethrough and alignable with the water flow passage in at least one of the multiple positions. The nozzle insert may also include a handle with an opening therein. A nozzle clip has a proximal end securable in the handle opening, and in one embodiment, a spare nozzle is secured to a distal end of the nozzle clip. In some versions, a spring insert supports a spring in the recess.
Abstract:
A stream redirecting device for a sprinkler comprising a shell-shaped body having a generally semi-circular shape in plan, with opposite inlet and outlet side edges, said body extending outwardly and upwardly from a base at a lower end and then upwardly and inwardly to a distal, arcuate edge at an upper end, with a maximum radius between said base and said arcuate edge; an inside surface of said shell-shaped body formed with a plurality of grooves between said inlet side edge and said outlet side edge, extending in a generally radial direction with entry ends adjacent said base and exit ends at said distal, arcuate edge; and wherein said grooves are formed with circumferential exit angles that vary substantially uniformly in opposite directions from a center one of said plurality of grooves to first and last of said plurality of grooves at said opposite inlet and outlet side edges, respectively.
Abstract:
A rotary, nutating sprinkler head includes a housing supporting a nozzle tube extending in a downstream direction, concentric with a vertical center axis of the sprinkler head; a spool assembly loosely supported on the starter tube, the spool assembly including a double- flanged spool and a water-deflection plate carried by the spool, the water-deflection plate formed with one or more grooves shaped to cause the spool assembly to rotate when impinged upon by a stream emitted from the starter tube, wherein one of the starter tube and the spool is provided with ac least one tilting lug located to maintain the spool assembly in a tilted or angularly offset orientation relative to the vertical center axis, thereby facilitating a wobbling action of the spool assembly during rotation.
Abstract:
A sprinkler head (10) includes a base (12) adapted to be secured to a component supplying water under pressure; an arc adjustment ring (22) rotatably mounted on the base (12); a nozzle (26) and a stream deflector (156) supported by an elongated stem (14) carried by the base (12), the nozzle (26) and the stream deflector (156) cooperating to define an (20) in the stem (14) and located downstream of the nozzle (26); the stem (14) and the nozzle (26) axially moveable relative to the base (12); and a drive train operative connected between the arc adjustment ring (22) and the nozzle (26) to rotate the nozzle (26) relative to the stream deflector (156) to thereby adjust the nozzle orifice between a pair of limit positions.
Abstract:
A sprinkler head (10) includes a fixed nozzle (20); and a rotor plate (40) spaced from the nozzle and mounted for rotation about an axis extending through the nozzle (20), and mounted for tilting movement about a horizontal axis. The rotor plate (40) has adjacent water distribution grooves (42) therein, selectively alignable with the nozzle (20), the grooves shaped and arranged to cause the rotor plate (40) to rotate in opposite directions. A flow reaction member (64) is secured to the rotor plate (40).
