Described are riser assemblies suitable for use with fluid dispensers. The assemblies include a container partially circumscribing a reservoir configured to contain a pressurized fluid, the container having a fluid inlet and a fluid outlet disposed therethrough. The assemblies may further include a signal processor situateable outside the container that is configured to receive a signal. The signal processor may be operatively connectable to a control valve that is operatively connectable to the fluid dispenser. The control valve may be configured to selectively control expulsion of the fluid through the fluid dispenser in response to the signal received by the signal processor. Embodiments of the riser assemblies include a utility conduit disposed at least partially within the reservoir and configured to enable secondary use of a resource from within the riser assembly and/or to accommodate transport and securing of the riser assemblies for use.

A rotor nozzle for a high-pressure cleaning apparatus is provided, with a housing having an inlet opening tangentially into the housing and an outlet arranged on an end wall and on which is arranged a pan-shaped, centrally broken recess. A nozzle body arranged in the housing, having a through channel, and supported with a spherical end in the pan-shaped recess has a longitudinal axis tilted toward the longitudinal axis of the housing. The nozzle body is brought into a revolving movement by liquid flowing through the housing and supported on a support surface, of which flow resistance elements, each having one baffle surface, are arranged downstream of on the wall of the housing. A guiding surface is arranged upstream of each baffle surface and is continuously adjoined by the baffle surface, wherein the guiding surface is aligned obliquely to a radial plane of the housing.

A shower head with alternating outlet function, includes: an inlet waterway with an inlet port, an outlet port, a waterway, an outlet terminal having at least two mutually independent outlet cavities rotatably distributed on a plane, and all have outlet holes, alternating inlet holes and synchronous inlets; the outlet holes are disposed on the outlet surface of the shower head; and an alternating cavity with alternating inlets, fixed to the outlet terminal. The alternating cavity is connected to all alternating inlet holes. The interior thereof is disposed with a hydraulic alternating device to make the alternating inlets to connect to the alternating inlet holes in alternating manner driven by water pressure. The synchronous inlets and the alternating inlets are switched to connect to the outlet port by a water diversion plate.

There is provided a turf cup assembly that attaches to a buried pop-up type sprinkler to blend a top of sprinkler both cosmetically and functionally with turf surrounding the sprinkler. The turf cup assembly includes a turf cup and a sleeve. The turf cup mounts to a riser of the pop-up type sprinkler. The turf cup contains soil and root structure of turf. The sleeve surrounds the turf cup and attaches to a top of a housing of a pop-up sprinkler. The sleeve can be at or slightly below grade, and the cup extends out of the sleeve during an irrigation cycle and retracts into the sleeve at the end of the irrigation cycle.

A liquid ejection apparatus for cleaning of a tank. The liquid ejection apparatus comprising: a base member having a first end for receiving the liquid from a liquid line, a rotary head that is rotatably connected to the base member and a rotary nozzle hub that is rotatably connected to the rotary head. The rotary nozzle hub comprises a primary liquid ejection nozzle for ejecting a liquid in a pattern towards an interior surface of the tank, and a secondary liquid ejection nozzle that is configured to, during at least a part of a revolution of the rotary nozzle hub, eject the liquid in a pattern towards an external surface of the base member.

A rotor nozzle structure has a chamber deployed with a rotor connecting to the water outlet and an adjusting element, wherein the rotor nozzle is capable of generating a directing stream and a wide-angle swirl stream, and the adjusting element is switchable by a rotational means for driving the rotor in a rotation or static status in the chamber.

A movable rack assembly for a washer having a generally rectangular frame. The frame includes a central hub connectable to a fluid source. A plurality of elongated tubular base members extends from the central hub and defines a bottom of the frame. A pair of spaced-apart elongated, tubular side members defines side portions of the frame and a space therebetween. Each of a plurality of spaced-apart transverse members has ends that are connected to one of the side members. The transverse members transverse the space defined between the side members. A rotary spray arm is attached to each of the transverse members. A plurality of corner spray nozzles on the frame directs fluid toward corners of the frame. The bottom members, the side members and the transverse members are fluidly connected with each other and fluidly connect the rotary spray arms and the corner spray nozzles with the central hub.

Disclosed is sprinkler system. The system comprises a gate valve. Further, a sprinkler frame is mounted on the gate valve. The sprinkler frame further consists of wires for connection. The system further comprises a generator. The generator is mechanically coupled with a rotor and a generator base. Further the system comprises of an electronic component. The system is housed in a sprinkler housing.

Irrigation nozzles are provided that irrigate a full circle coverage area with different maximum throw radiuses. The nozzle may include two bodies, one nested within the other, that acting together form the full circle coverage area. The two bodies collectively define an annular exit orifice with one of the bodies defining the inner radius and the other body defining the outer radius. A flow restrictable inlet may be used to adjust flow through the nozzle and to adjust the maximum throw radius. The nozzle may also include a flow reduction valve to reduce the throw radius from a maximum distance and may be adjusted by actuation of an outer wall of the nozzle. A deflector for use with an irrigation nozzle is also provided.
