A rotating sprinkler includes a housing and a movable core. The core can assume retracted and extended states relative to the housing and incudes a cover, an impact member and a stream deflector. In the extended state, both the cover and the impact member can pivot between pivoted and non-pivoted states about a hinge defining an axis H generally orthogonal to axis X and the stream deflector is fixed against rotation about the hinge.

A specialty nozzle is provided having a pattern adjustment valve that may be adjusted to irrigate a substantially rectangular irrigation area. The nozzle may be further adjusted to irrigate three different substantially rectangular irrigation areas. The nozzle is adjustable to function as a left strip nozzle, right strip nozzle, and side strip nozzle. The strip irrigation setting may be selected by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a flow reduction valve to set the size of the rectangular irrigation areas and may be adjusted by actuation of an outer wall of the nozzle. Other specialty nozzles are provided having a fixed pattern template to irrigate a rectangular area, such as left strip, right strip, or side strip.

An irrigation device includes a body defining a fluid passage; a slider movably coupled to the body, wherein the slider includes a body defining a plurality of apertures and a plurality of projections extending away from the body; a plurality of flexible jets coupled longitudinally to the body, wherein the plurality of flexible jets receive fluid from the fluid passage, and wherein each jet is received by an aperture in the plurality of apertures of the slider; and a toggle rotatably coupled to the body and to the slider, wherein the toggle is rotatably coupled to the body in substantial alignment with the plurality of jets, and wherein rotation of the toggle in a first direction moves the slider to cause at least one projection of the slider to engage with at least one jet to adjust a position of the at least one jet.

A rotating sprinkler is configured with only three components without need of any other manufactured component. The three components are constituted by abase component connected to a water source, a rotating head component from which a water stream is emitted which is rotatably mounted on an element of the base component, and a gravitating hammer component pivotally mounted on the head component that causes intermittent rotary motion of the head component about a vertical rotation axis by intermittently engaging the emitted stream and providing in response a reaction force. The hammer component is configured to intercept the emitted water stream within an interior space between a deflecting surface and a ramping surface when downwardly pivoted and to urge the intercepted water stream to flow upwardly along the ramped surface and to impinge upon the deflecting surface, causing the hammer component to pivot upwardly prior to being gravitated.

A pressure regulator for controlling flow of a fluid therethrough is provided. An upper housing member and a primary diaphragm define an upper chamber and a lower housing member and the primary diaphragm define a lower chamber. The pressure regulator further includes: a valve assembly provided within the upper chamber for controlling the flow of the fluid from an inlet body into the upper chamber; a secondary diaphragm provided within the lower chamber and defining a secondary diaphragm driving chamber; and a passageway connecting the inlet body and the secondary diaphragm driving chamber. During operation, the secondary diaphragm driving chamber is filled with the fluid at the inlet pressure, thereby subjecting the secondary diaphragm to the inlet pressure and generating the force for actuating the valve's disengagement from the inlet body. The pressure regulator functions to maintain the outlet pressure at a value that is a predetermined fraction of the inlet pressure.

Rotary nozzles and deflectors for use with rotary nozzles are provided. The deflector includes a number of flutes that deliver fluid streams radially outwardly from the deflector. Fluid striking the flutes of the deflector cause the deflector to rotate, and the flutes subdivide fluid impacting deflector into multiple fluid streams that are distributed radially outwardly to surrounding terrain as the deflector rotates. Each of the flutes have the same curvature, although they may have different inclinations to distribute fluid streams at different trajectories. The flutes may also include blocking and downward-facing features at the ends of the flutes to improve the evenness of the fluid distribution in the irrigation coverage area.

A driving structure for a garden sprinkler comprising: a main body, a sprinkler unit, at least one adjusting base, and at least one driving member. The main body has a main base and an upper cover corresponding to each other, the main base being hollow and having an assembly opening at an end configured to accept the sprinkler unit and for connection to a hose connector; the main base having a recess and a streaming surface, a plurality of first through apertures disposed on the streaming surface corresponding to a plurality of second through apertures with longer lengths disposed on the upper cover; the recess accepting the adjusting base and forming an enclosure with the upper cover; at least one through hole disposed in a middle portion of the main body and defined by integrating the main base with the upper cover, the through hole provided with a positioning baffle.

Implementations of a decorative rotating lawn sprinkler are provided. In some implementations, the decorative rotating lawn sprinkler comprises a rotating sprinkler head, a figurine, piping, and a support.

In some implementations, an example method of use of the decorative rotating lawn sprinkler comprises anchoring or otherwise supporting the decorative rotating lawn sprinkler on a lawn or other surface, connecting the decorative rotating lawn sprinkler to a water source, and operating the decorative rotating lawn sprinkler to disperse water from the connected water source over a circular or semi-circular area of the lawn or other vegetation.

An irrigation nozzle is provided with a grit diversion feature to divert grit away from the interior of the nozzle. The nozzle includes a pattern template that defines the irrigation pattern produced by the nozzle. The pattern template includes one or more flow channels that may be susceptible to clogging with grit. The grit diversion feature includes one or more grit vents to redirect grit away from the interior of the nozzle and may further include an inner wall about the central hub that helps protect the central hub from intrusion by grit.
