An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure air stream and passes the fluid through an electrode inside a nozzle assembly to charge, such as negatively charge, droplets of the atomized fluid. The system uses a unique nozzle design that is configured to optimally atomize the fluid into various sized droplets.

An aquarium includes a container that contains a liquid. A spout includes a first leg that extends along a first axis from an inlet positioned in a bottom portion of the aquarium space to a bend, and a second leg that extends along a second axis from a flow aperture formed adjacent the bend to an outlet. The spout is arranged to direct a portion of the liquid from the inlet to the outlet. A cap is coupled to the spout and is rotatable between a first position and a second position. The cap includes a seal element positioned to form a seal between the cap and the spout, and a flow control member fixedly attached to the cap and sized to completely block the flow aperture when the cap is in the first position and to completely uncover the flow aperture when the cap is in the second position.

A pump for dispensing a fluid, has a pump head , a piston body with a piston, a pump chamber limited by a pump chamber body, an inlet valve and an outlet valve, the piston being moveable by respective movement of the pump head between an upper starting position and a lower end position. A return stroke force for a return stroke from the lower end position into the upper starting position is provided by a bellows, formed by two bellows arranged one above the other, Each of the bellows is folded up, when moving the pump head into the lower end position, by exerting a compression force on the pump head, the first bellows receiving the compression force by direct engagement with the pump head, the second bellows receiving the compression force only by engagement with the first bellows.

An aerosol actuator has a main body member, a nozzle member defining an outlet opening, and a selector member. The outlet opening defines a fluid flow direction. The selector member is moved to obtain different fluid spray patterns. The selector member is distal to the nozzle member and the fluid flow direction.

A sprinkler riser extension kit for elevating a sprinkler head and maintaining a fixed constant pressure at an outlet end in an existing pop-up sprinkler is disclosed. The extension kit comprises a gripping head having a channel defined therethrough and a riser stem extension enclosing a pressure regulator assembly, the extension stem being slidable through the channel of the gripping head. The gripping head engages a cap of an existing sprinkler and the extension stem engages the sprinkler riser of the existing sprinkler. The pressure regulator assembly defines an internal hollow channel. A valve assembly is integrally connected to a spring circumvolving the channel. The spring exerts a constant downward force on the valve assembly. When under pressure, the valve assembly exerts an opposing force against the spring and the two forces cooperate to maintain a constant pressurized release of fluid at the outlet.

A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser (100), configured to draw fluid up from a container. A nozzle assembly can include a nozzle (160), and a nozzle slide (112). The nozzle slide can be configured to slide and/or rotate relative to the shroud (102) to provide different dispensing modes. In alternative examples, the nozzle (160) can be configured to rotate in 30 degree increments relative to the shroud (102) to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.
