The invention relates to an atomizer unit of a minimal quantity lubrication system (3) for cooling and/or lubricating a chip-removing machining process between a tool (5) and a workpiece (6) at a machining station, wherein the atomizer unit (2) has a chamber arrangement (8) with a chamber arrangement interior (9), at least one first supply duct (10) for supplying a first compressed air stream (11) into and through the chamber arrangement interior (9) to a continuation duct (12) and an injection valve (13) for injecting a coolant and/or lubricant (4) into an injection region (14) into the first compressed air stream (11) in the chamber arrangement interior (9). It is proposed that the atomizer unit (2) has at least one second supply duct (15) for supplying a second compressed air stream (16) into and through the chamber arrangement interior (9) to the continuation duct (12), wherein the atomizer unit (2) is configured such that the second compressed air stream (16) joins the first compressed air stream (11), and any coolant and/or lubricant (4) injected into the first compressed air stream (11), downstream of the injection region (14) to form a transport stream (17) for transporting the injected coolant and/or lubricant (4), and wherein the transport stream (17) is conveyed through the continuation duct (12) to the machining station (7).

A spray applicator assembly discharges distributable product from a cartridge using low air pressure. The cartridge is held captive between a piston advancing from the rear to expel contents and a nozzle snugly attached at the front to receive expelled contents and to convert the contents into droplets by subjecting the contents to an array of focused high velocity air streams. The nozzle has an open barrel design and is able to discharge a variety of liquid or viscous distributable product without readjustment, other than resetting a proportioning valve in the low pressure air feed line. An air chamber immediately in front of the cartridge nose provides constant backpressure, which dominates to cleanly stop flow of distributable product into the nozzle whenever the piston stops advancing. When the piston resumes advancement, the flow restarts cleanly. Clean stopping and starting saves distributable product from waste. Variations in the distributable product might include, without limitation, a broad variety of materials including coating materials and combustibles.

Present disclosure relates to a injector, which comprises a first lance, provisioned with at least one first inlet port, to receive a first fluid. Further, a second lance is coaxially disposed within the first lance, and provisioned with at least one second inlet port, to receive a second fluid. The injector further includes a tube member, disposable within the second lance to receive the first fluid at one end, while sealed at another end. The tube member is provisioned with at least one recess for the first fluid in the tube member to mix with the second fluid and form the effervescent fluid. The effervescent fluid is then dispensed through at least one of a first exit port of the first lance and a second exit port of the second lance. The injector may be employed in applications such as, fuel injection, spray coating and the like.

A bubble generating device is disclosed which includes: a bubble generator including a tubular body, a liquid introduction port, a gas introduction port, and a discharge port; and a gas supply unit including a gas supply port, a pressurized gas being supplied to the bubble generator through the gas supply port, wherein the flow passage of the bubble generator extends substantially along a same axis, a plurality of reduced diameter portions each having an inner diameter reduced are provided along a direction along which the liquid flows, and gas-liquid mixing portions are provided downstream of the respective reduced diameter portions in a contiguous manner, each of the gas-liquid mixing portions having an inner diameter larger than a minimum inner diameter of each of the plurality of reduced diameter portions, and the gas introduction port of the bubble generator is formed of a plurality of through holes.

A foam dispenser includes a dispensing a mixing chamber for receiving liquid from a liquid source and air from an air source, a conduit, and an agitator downstream of the mixing chamber in the conduit.

[Problem] To provide a flow path tube that prompts gas/liquid stirring of fluids flowing through a tube channel, enables adjustment of the flow rate, and furthermore suppresses passage of foreign substances. [Solution means] A flow path tube 1 is configured by inserting and disposing within a tube channel 12 of a flow path tube body 10 at least one or more porous materials 20 having a continuous void structure and a necessary length/a necessary diametrical dimension. Moreover, at least one or more ejection holes 18 are formed at given positions in the flow path tube body 10 or in the porous material 20 to form a jet nozzle tube 14 using the flow path tube 1. Furthermore, a valve body 26 is attached to the base end 10c of the flow path tube body 10 to form an aerosol valve tube 16 using the flow path tube 1.
