To eliminate a flow regulator that regulates a fluid intake amount and that is attached to an intake fluid introduction tube connected to an ejector, and to make a device comprising the ejector more compact, the present invention provides an ejector in which: an inflow part 1, which is formed into a tube shape and into which a high-pressure fluid flows, and an outflow part 2, through which the fluid flows out, are disposed in a straight line along a longitudinal direction; a throttling part 3, which has a cross-sectional area smaller than the cross-sectional area of the inflow part 1 and outflow part 2 orthogonal to the longitudinal direction, is formed in the portion where the inflow part 1 and the outflow part 2 are joined; an intake fluid introduction tube 4, through which the fluid taken in is introduced and which has no flow regulator, is connected to the throttling part 3; and the intake fluid introduction tube 4 communicates with the throttling part 3, wherein a reduced-diameter part 5, which is reduced in size relative to the cross-sectional area of the outflow part 2 in accordance with the fluid intake amount, is provided to the fluid-discharging side of the outflow part 2. A baffle plate, which blocks the flow of the fluid discharged from the reduced-diameter part 5, can be disposed downstream of the reduced-diameter part 5.

Disclosed is a carbonated beverage having new level of quality and wherein dissolved carbon dioxide is not released easily, the bubbles are perceived as being minute during ingestion, and the carbonation sensation can be freely controlled. Further disclosed is a method for producing said carbonated beverage. Dissolved carbon dioxide gas is caused to be more minute by means of generating cavitation in a liquid containing carbon dioxide gas by passing the liquid through a device that can generate cavitation under pressurized conditions.
An apparatus for production of microfluid mixed liquid fuel that is capable of mixing a microfluid in a liquid fuel through micronization of mix fluid by means of an ejector type microfluid generating unit. There is provided an apparatus for production of a microfluid mixed liquid fuel having a microfluid mixed and dispersed in a liquid fuel, characterized by including ejector type microfluid generating unit (6) for mixing and dispersing of a microfluid in a liquid fuel and pump (11) for pressurizing of a liquid fuel and feeding of the same to the ejector type microfluid generating unit (6), which ejector type microfluid generating unit (6) has a liquid fuel flow channel for introduction of the liquid fuel pressurized by the pump (11), a mix fluid introduction flow channel for introduction of a fluid to be mixed in the liquid fuel and a microfluid generating space and microfluid mixing compartment for micronizing and dispersing of the mix fluid in the liquid fuel.

COLLECTIVE MIST NOZZLE AND FIRE EXTINGUISHING FACILITY EQUIPPED WITH THAT MIST NOZZLE
One collective mist nozzle (100) which comprises an orifice plate (1) having a plurality of orifices for ejecting liquid, a control plate (2) arranged to allow a recess constituting a swirl chamber communicating with each orifice, a groove constituting a channel entering the recess toward almost the swirling direction of the liquid, and a second inlet for introducing the liquid to the groove to communicate with respective orifices, a channel plate (3) arranged to communicate with the second inlet and having an opening working as the supply path of the liquid, and a lid (4) having a first inlet for introducing the liquid to the opening, and which is constituted by stacking these four kinds of planar bodies. With such an arrangement, the mist nozzle can deal with complicated mist injection conditions and can be installed in a limited space. The mist nozzle is especially effective as a fire extinguishing facility.

B05B 1/14 - Nozzles, spray heads or other outlets, with or without auxiliary devices such as valves, heating means with multiple outlet openingsNozzles, spray heads or other outlets, with or without auxiliary devices such as valves, heating means with strainers in or outside the outlet opening
Provided is an aeration apparatus, which is enabled, when stopped, to prevent an air injection nozzle from being choked, by keeping the air injection nozzle out of contact with an object to be treated. An aeration apparatus (1) is dipped in the object and blows air to aerate the object. The aeration apparatus (1) comprises a lower cylinder (3) having such an opening (3a) formed at its lower end that the object flows thereinto, an air reservoir (4) formed of a space defined by an outer cylinder (4a) merging into the upper portion of the lower cylinder (3) and by an inner cylinder (4b) and a ceiling (4c) arranged at a spacing in that outer cylinder, an air feeding pipe (6) arranged in the ceiling (4c) and having a plurality of air injection nozzles (6a) for injecting air toward the object, a compressed air feeding pipe (7) connected outside of the air reservoir to the connecting pipe (6b) of the air feeding pipe (6) for feeding the compressed air, and an upper cylinder (5) merging into the inner cylinder (4b) of the air reservoir (4) and having an opening (5a) formed at its upper end for the object to flow out.
A discharge flow passage of a pressure dissolving device simply formed and capable of fulfilling such requirements that a high dissolving efficiency must be provided. The discharge flow passage of the pressure dissolving device for dissolving air into water is characterized in that at least one reduced diameter part is formed therein and a radius or a taper is applied to at least one end part of the reduced diameter part.
