Rotating spray systems and related methods for enhancing spray performance can include one of more rotating spray assemblies formed of a plurality of individual, linear distribution manifolds to define a rotary cage. The rotary cage is fluidly coupled to a rotating distribution block on a distribution valve, with each linear distribution manifold being fluidly coupled to one of a plurality of distribution conduits defined in the rotating distribution block. The distribution valve further includes a fixed distribution block having an arcuate aperture defined therein. The rotating distribution block rotates relative to the fixed distribution block to individually and sequentially engage each distribution conduit with the arcuate aperture. When the individual distribution conduits are fluidly engaged with the arcuate aperture, pressurized fluid supplied to the distribution valve is supplied to the corresponding linear distribution manifold for spraying by one or more spray nozzles fluidly connected to each linear distribution manifold.

The fluid-ejection device (100) comprised a first member (110) having an inlet suitable for being connected to a source of fluid (120); a second member (130) that can be moved relative to the first member (110); and a control member (150) arranged to be at least in a first condition, in which the control member (150) is at least substantially inside the second member (130) preventing the flow of fluid through the second member (130) to define a first stroke (51) of the second member (130) where no discharge of fluid is allowed out of the device (100); and a second condition, in which the control member (150) is at least substantially outside the second member (130) allowing the flow of fluid through the second member (130) to define a second stroke (S2) of the second member (130) along which discharge of fluid is allowed out of the device (100).

A device that intermittently coats a moving surface with a paste containing electrochemically active particles including a nozzle having a slot-shaped delivery opening, a paste reservoir from which paste being supplied to the delivery opening via a transport channel, a rotary valve having a rotatably mounted control axle that enables the paste supply to the delivery opening in a first switching position and, in a second switching position, blocks the transport channel and disconnects a section of the transport channel extending as far as the delivery opening from the paste supply, and a reduced pressure source in communicating connection with the rotatably mounted control axle via a reduced pressure channel, wherein the rotatably mounted control axle comprises a passage via which the paste reservoir is in communicating connection with the delivery opening in the first switching position and via which the delivery opening is in communicating connection with the reduced pressure source in the second switching position.

A water sprinkler includes a base configured to rest on a surface, a barrel assembly, a primary fluid inlet, and a plurality of nozzle structures. The barrel assembly is rotatably supported by the base and defines a plurality of fluid channels, each fluid channel extending from a corresponding fluid inlet of a plurality of fluid inlets to a corresponding fluid outlet of a plurality of fluid outlets. The primary fluid inlet is supported by the base and is configured to be fluidly coupled to a selected fluid inlet by rotating the barrel assembly to a position that aligns the selected fluid inlet with the primary fluid inlet. The plurality of nozzle structures is supported by the barrel assembly. Each nozzle structure (i) is configured to sealingly engage at least one fluid outlet of the plurality of fluid outlets, and (ii) defines an outlet opening configured to emit a fluid flow.

A delivery tube and cap are configured to be connected to a container that houses fluid to be delivered to a nasal cavity. The delivery tube includes an inner cannula that is positioned within an outer cannula. Each of the cannulas includes an outlet. The delivery tube and cap are configured to provide relative axial movement between the cannulas. The cannulas are positionable between a first axial position that aligns the outlets to deliver the fluid out of the device in a lateral direction and a second axial position that misaligns the outlets to impede the fluid from being delivered out of the device in the lateral direction.
