Disclosed herein are a spray nozzle for an attemperator and an attemperator including the spray nozzle. An attemperator according to an embodiment includes: a steam transfer pipe through which steam is transferred; a fixed pipe which is fixed to an outer surface of the steam transfer pipe; and a spray nozzle, which is coupled to the fixed pipe, disposed in the steam transfer pipe and configured to spray cooling water into the steam transfer pipe. The spray nozzle includes, on an outer circumferential surface thereof, at least one support that protrudes toward the fixed pipe. The spray nozzle is spaced apart from the fixed pipe.

A liquid dispersion device comprising an elongated dispersion body comprising a first end extending in a first direction and forming an elongated dispersion body comprising a first end positioned at an acute angle relative to a longitudinal axis of the elongated dispersion body, a second end positioned at an obtuse angle relative to the longitudinal axis of the elongated dispersion body, a plurality of nozzles extending outwardly from a forward surface of the dispersion body and a source connector on a rear surface of the dispersion body, the source connector in fluid communication with the plurality of nozzles. A first nozzle among the plurality of nozzles is positioned on the forward surface of the dispersion body at the first end of the dispersion body and a second nozzle is positioned on the forward surface of the dispersion body at the second end of the dispersion body.

A rain simulation system that replicates realistic raindrop characteristics for controlled testing is invented. The rain simulation system can be used as a stand-alone system with wind using a blower fan or in a wind tunnel, and without wind to create wind-driven and vertically falling rain droplets, respectively. In addition, methods to simulate rainfall for stationary and moving objects such as a road passenger vehicle are proposed. The rain simulation system is fully adjustable for a range of droplet size, impact velocity, rain intensity, rain coverage via the use of dripping nozzle devices and positioning of system components. The rain simulation system dispenses distinct droplets or continuous streams that can be broken down into droplets by wind. A rain nozzle device is coupled with a rain reservoir, and multiple nozzles are used to create a rain matrix, the full matrix is integrated with a rain rack and rainwater flow control strategy.

A rotatable sprinkler comprises a base with a continuous curved surface and a rotation element disposed rotatably and relatively to the base. The rotation element has an outlet that connects to a water source. A decorative unit is disposed on a support, part of which is located on the rotation element and the free end of which is in contact with the continuous curved surface of the base. Therefore, the decorative unit may rotate relatively to the base, or move up and down when the free end of the support is pressed against the continuous curved surface.

The subject matter of this specification can be embodied in, among other things, a fuel delivery component, a substantially rigid, unitary structure formed as a single piece of material, and at least a first seamless lumen defined by the unitary structure as a first loop.

The method can include: sampling measurements of a vehicle in-situ, generating a model based on the measurements, and determining a wash path based on the model. The method can optionally include washing the vehicle according to the wash path.

The present application discloses a faucet head that controls pressure to lock its associated faucet into a fixed position. The basic structure may comprise an inlet, a faucet head body, an outlet and at least one internal water channel. The faucet head may adjust the faucet pressure to allow for the faucet head to become fixed in numerous positions, or to be used as a spray head. The faucet head would allow for a faucet acting in a flexible spray manner to become rigid and fixed in place at a user chosen position. The faucet head would also allow for the user to transform the faucet from fixed position to a flexible spray operation.

A liquid flow-focusing apparatus for droplet atomization may include a dispensing body, including a liquid duct and a gas duct defined therein. The apparatus may include a plurality of nozzle wells defined in the dispensing body. The apparatus may include a plurality of flow-focusing nozzle inserts. Each nozzle well of the plurality of nozzle wells may be shaped to house a flow-focusing nozzle insert of the plurality of flow-focusing nozzle inserts. Each flow-focusing nozzle insert of the plurality of flow-focusing nozzle inserts may be housed in a corresponding nozzle well of the plurality of nozzle wells. Each flow-focusing nozzle insert of the plurality of flow-focusing nozzle inserts may be in fluid communication with the liquid duct and the gas duct.

According to some embodiments, an oscillating sprinkler system is provided that includes: a central tubular portion having at least one row of flexible nozzles; a cam plate located inside a peripheral wall of said central tubular member, said cam plate having a plurality of cam slots for adjusting positions of said flexible nozzles upon rotation of said cam plate within said peripheral wall; and said peripheral wall including a window via which an edge of said cam plate is observable during rotation of said cam plate such as to designate an extent of angular displacement of the nozzles based on the positioning of the cam plate within the window.

A handheld pet spray wand may be configured for use in washing or bathing a pet, for example, a dog. The handheld pet spray wand may be configured for attachment to a hose that is further attached to a water supply source. The handheld pet spray wand may be operable to have a number of spray modes to assist in the cleaning of the pet. The handheld pet spray wand may further be configured to provide selective nozzle array sizes designed for both small and large pets. The form factor of the spray wand may further be ergonomically formed to provide a spray pattern conforming to the body of the pet.
