摘要： A spray nozzle and method are provided in which fluid flow through the nozzle is inverted and in which a portion of a nozzle body may be rotatable adjusted to distribute water in a desired arc of coverage. Water first flows upwardly through the nozzle body, into an adjustable arcuate chamber defined by a helical interface in the nozzle body, is inverted, and is redirected downwardly through the nozzle body. Water may flow upwardly through a first set of flow passages and downwardly through a second set of flow passages. Water is directed downwardly against a distribution surface having an uneven surface profile for improved water distribution to terrain near to and distant from the nozzle. The water is directed downwardly against the distribution surface in the nozzle body and outwardly to surrounding terrain. The flow passages may be adapted to provide a matched precipitation rate for nozzles with different throw radiuses.

摘要： A variable arc sprinkler may be set to numerous positions along a continuum to adjust the arcuate span of the sprinkler. The sprinkler includes a nozzle body and a valve sleeve that helically engage each other to define an arcuate slot that may be adjusted at the top of the sprinkler to a desired arcuate span. The sprinkler may include a flow rate adjustment device that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion may cause a throttle control member to move axially to or away from an inlet, or may cause one or more restrictor elements to open or close, to control the flow rate of the sprinkler.

摘要翻译： 可变弧喷头可以沿着连续体设置到多个位置，以调整喷洒器的弓形跨度。 喷洒器包括一个喷嘴体和一个阀套，它们彼此螺旋啮合以形成可以在喷洒器顶部调整到所需弓形跨度的弧形槽。 喷洒器可以包括可以通过喷洒器的外壁部分的致动或旋转来调节的流量调节装置。 外壁部分的旋转可以导致节气门控制构件轴向移动或远离入口，或者可以使一个或多个节流元件打开或关闭，以控制喷洒器的流速。

摘要： A pop-up irrigation device for use in a low pressure irrigation device is described. The device has a housing, a riser partially extensible from the housing and a nozzle body removably attached to an end of the riser in a non-threaded manner, such as using a snap-fit. One, two or more connection tubes or ports may extend laterally from the housing and can each be configured to be connectable to flexible irrigation tubing. An annular cap can be attached to the open end of the housing and may include an annular, radially-inward extending seal. The closed end of the housing may include a depending stake with a plurality of blades to facilitate mounting of the housing relative to the ground.
