An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit configured to atomize the liquid to generate an aerosol; a discharge port configured to discharge the generated aerosol to the outside of the aerosol supply device; and a volatilization preventing part (solenoid valve or duckbill valve) capable of opening and closing a passage (first passage or second passage) through which at least one of the liquid or the aerosol flows between the accommodating part and the outside of the aerosol supply device.

This aerosol supply device is provided with: an accommodating section (cartridge) that accommodates a liquid; an atomizing unit that atomizes the liquid to generate an aerosol; and an atomizing amount adjusting unit (gyro sensor and control unit) that adjusts the atomizing amount of the atomizing unit. The aerosol supply device is characterized in that the atomizing amount adjusting unit (gyro sensor and control unit) stabilizes the atomizing amount regardless of the inclination of the aerosol supply device within at least a certain range.

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit having a storing part to store the liquid, the atomization unit being configured to generate an aerosol by atomizing the liquid; and a temperature control part configured to control the temperature of the liquid at a given location between the accommodating part (cartridge) and the storing part.

The present invention provides unique pressure actuated valves and related methods that may be used in applications where a plurality of fluid emission devices are provided on a plurality of lines containing fluid under pressure, in order to prevent fluid from escaping from the fluid emission devices until a consistent threshold or predetermined level of fluid pressure is obtained in the lines, without causing significant water pressure and/or flow loss through the valves. Valves of the present invention include a housing having an upper body and a lower body that may be coupled together to form an inner chamber, the lower body having an inlet in communication with a source of fluid under pressure, the upper body having an outlet in communication with a fluid emission device. A hollow movable fluid transmission piston is provided in the chamber for communicating between the inlet and outlet. The chamber formed between the upper and lower bodies may be provided with cup seals at opposite ends of the chamber to reduce friction and prevent fluid from entering therein, and a side air vent. A wider lower end of the piston is urged toward the lower housing body using a biasing mechanism, which pushes an O-ring at the lower end against a stop to prevent fluid from entering into the hollow center of the piston. When fluid with a sufficient pressure is provided from the source, it pushes the O-ring away from the stop and against the urging of the biasing member, allowing fluid to flow around the stop, through the center of the piston, and out through the upper body into the fluid emission device. The vent in the chamber allows air inside the chamber (surrounding the biasing mechanism) to escape so that there is no added air pressure within the chamber to be overcome by the fluid pressure.

A fire extinguisher discharge nozzle is provided and includes sidewalls and a biasing element. The sidewalls define an aperture through which a medium(s) is dischargeable and are adjustable between multiple first and multiple second positions associated with dilated and constricted conditions of the aperture, respectively. The biasing element is configured to bias the sidewalls toward assuming one of the multiple first or multiple second positions. The sidewalls are drivable toward assuming the other one of the multiple first or multiple second positions in opposition to bias applied by the biasing element in accordance with a characteristic of the medium(s).

The invention relates to a switching apparatus for high pressure tools, comprising a holding device and two or more high pressure tools for cleaning purposes, a drive device, and a rotary body that is rotatable relative to the holding device about an axis of rotation by means of said drive device, an adjusting device with which one of the high pressure tools is selectively transferable from an inoperative position into an operating position, in which operating position the high pressure tool is coupled to the rotary body in a rotationally fixed manner and is rotationally drivable about a tool axis by way of said rotary body, wherein the switching apparatus comprises or forms a supply channel for pressurized cleaning liquid and the respective high pressure tool comprises or forms a tool channel for cleaning liquid, which is in flow connection or can be brought into flow connection with the supply channel during operation, wherein the switching apparatus further comprises a valve device with which the supply channel is selectively unblockable and closable, wherein the supply channel is formed in the rotary body at least in sections and the valve device is arranged on the rotary body.

An emitter forms a flow path that runs to a discharge part from a water collecting part for receiving an irrigation liquid in a tube. The flow path includes a flow rate control part which includes: an end surface including a concave inclined surface that faces a film for receiving the pressure of the liquid inside the tube; a hole that opens at the center of the flow volume control part and connects to the discharge part; and a groove crossing the inclined surface and running to the hole. When the film adheres to the inclined surface as a result of the pressure of the irrigation liquid inside the tube, the flow volume of the irrigation liquid inside the emitter is controlled so as to be a volume that can pass through the groove.

A liquid dispensing system includes at least one container for storing the liquid to be dispensed, the at least one container having a neck defining an fill opening for the liquid. The system includes a liquid dispensing device releasably connectable to the at least one container, an exchangeable cartridge for an additive to be mixed with the stored liquid, where the cartridge is accommodated in the neck, and means for opening the cartridge. The cartridge includes a one-piece hollow body filled with the additive and with a pressurized gas, and the opening means include at least one piercing member arranged to pierce a wall of the hollow body. A method of dispensing a liquid by using the liquid dispensing system, and a cartridge for use in the liquid dispensing system and/or method.

A showerhead bracket including a bracket body, a spool rotatable relative to the bracket body, and a flow control knob non-rotatably connected to the spool such that the flow control knob and the spool rotate together relative to the bracket body. The flow control knob non-slidably connected to the spool to inhibit axial disengagement of the flow control knob from the spool.

A spray bar injector including a spray bar defining a longitudinal axis and including a fluid inlet and a plurality of spray outlet orifices spaced apart longitudinally in a direction along the longitudinal axis. A check or spray valve is operatively connected to each spray outlet orifice. A master valve is in fluid communication with the fluid inlet, operatively connected to divert flow from the fluid inlet into a first passage and block flow into a second passage in a first position to open the check valves and issue a spray from the spray outlet orifices, and to divert flow from the fluid inlet into the second passage and block flow into the first passage in a second position to close the check valves and block issue of spray from the spray outlet orifices.
