An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

The present application belongs to fluid control equipment, in particular, relates to directional controlling mechanism of fluidic sprinkler, comprising a rear reversing mechanism, a front reversing mechanism and a signal stream switching mechanism. A limiting shift rod of the rear mechanism rotate around a locating rod as the center after touching a limiting ring, then realize the reversing of the limiting shift rod. The reverse action of the limiting rod will finally lead a reversing arm to rotate by way of driving a reversing locating block, a rear reversing rod and a front reversing rod to rotate. The rear reversing mechanism, the front reversing mechanism and the signal stream switching mechanism act together, so as to switch a left-side signal stream nozzle and a right-side stream nozzle of a fluidic sprinkler, and bring about the reversing of the rotation direction of the fluidic sprinkler. Directional controlling mechanism of fluidic sprinkler is in a stepping state respectively in the clockwise and the counter clockwise working modes, so that the impact force on a rotary body is small, critical components tend to have a longer working life, an intermediate position does not exist during the reversing of the sprinkler, and the switching of the sprinkler is stable and reliable.

A fluid delivery system utilizes Bernoulli pressure differentials and kinetic forces is provided. The system includes a pressurized channel in fluid communication with a flexible pressurized line for translating pressurized fluids to a mixing chamber. The mixing chamber is also in fluid communication with a source channel receiving fluids from a flexible source line. The mixing chamber is configured for entraining the source fluids with the pressurized fluids 26 using Bernoulli principles. Kinetic valves may be used in conjunction with, or in lieu of, the Bernoulli siphoning.

A rudder-directed tube delivery sprinkler head. A rudder configured to direct water into a tube, triggering distribution of water around an axis. Adjustable stoppers contact a rudder assembly, causing the rudder to pivot, directing water into a different tube and changing the direction of rotation.

An irrigation sprinkler has a vertical axis (A) and is configured to emit a liquid jet. The sprinkler includes a base and a head operatively connected to the. A reciprocal element rotatably mounted to the head is configured to undergo reciprocal motion about the vertical axis (A), in response to being impacted with the liquid jet from a nozzle belonging to the head. The reciprocal element has a diffuser arm which carries a plurality of integrally formed, spaced apart diffuser posts which are configured to be hit by, and diffuse the liquid jet during the reciprocal motion.

The present invention relates generally to an improved rotating lawn sprinkler capable of precisely watering lawns with straight edges without over-spraying onto sidewalks and fences. More specifically, the invention relates to a rotating sprinkler with a plane of rotation is adjustable upwards or downwards from horizontal that will water in a triangle pattern when the plane of rotation is angled downwards from horizontal or a diamond pattern when the plane of rotation is angled upwards from horizontal. These watering patterns are possible because the axis of rotation is adjustable, which adjusts the plane of rotation. By adjusting the plane of rotation, the nozzle trajectory is being continually increased or decreased as the sprinkler rotates, which causes the watering pattern to form patterns with straight lines rather than traditional watering arcs.

An irrigation sprinkler including a base defining an axis, a pressurized water inlet mounted onto the base, a nozzle, communicating with the inlet, and providing a pressurized water stream which is generally outwardly directed relative to the axis and a water stream deflector for engaging the pressurized water stream and deflecting at least part of the water stream azimuthally with respect to the axis, the deflector including a first pressurized water stream engagement surface and a second pressurized water stream engagement surface downstream of the first engagement surface, the first engagement surface having a pressurized water stream directing configuration arranged to direct a first portion of the stream impinging thereon, which does not exceed a predetermined quantity, onto the second surface and to direct at least a second portion of the stream impinging thereon, which at least a second portion exceeds the predetermined quantity, not onto the second engagement surface.

An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

An impact sprinkler is provided. The impact sprinkler includes a stem; a first trip collar rotatably coupled to the stem, the first trip collar including a first trip flange; a second trip collar rotatably coupled to the stem, the second trip collar including a second trip flange; a nozzle body including a spray nozzle structured to emit a fluid stream, the nozzle body rotatably coupled to the stem; and a base coupled to an end of the stem opposite an end of the stem where the first and second trip collars are positioned such that the nozzle body is an intermediary between the base and the first and second trip collars.

A rotation limitation mechanism for an impact sprinkler is provided. The rotation limitation mechanism includes a nozzle body including a first protrusion, a second protrusion, and a spray nozzle structured to emit a fluid stream; a first trip collar including a first trip flange; a second trip collar including a second trip flange; and, a trip paddle including a first arm and a second arm, wherein the first arm is structured to selectively engage with each of the first and second trip flanges while the second arm is structured to selectively engage with each of the first and second protrusions to control a rotational amount and a rotational direction of the nozzle body about a first axis.
