A dispenser for applying at least two compositions, the dispenser including at least two reservoirs for storing the at least two compositions separately, at least two pumps for pumping the at least two compositions, which pumps have different strokes, an exit orifice, and an actuator assembly. The difference between the first stroke and the second stroke is accommodated through flexure of a flexing member in the actuator assembly. The first composition includes microcapsules and the second composition includes a volatile solvent.

An injector includes a nozzle body extending along a longitudinal axis and at least one spray hole extending through a portion of the nozzle body to output a fluid from the injector. The spray hole includes at least one groove. The groove is configured to facilitate efficient mixing of the fluid with air or other surrounding materials for enhanced performance of the injector and/or other components associated with the injector.

A nozzle arrangement connected to a source of pressurized fluid mat produces a series of fast pulsed discharges of fluid in quick succession wherein the nozzle arrangement comprises a nozzle body with an inlet for the pressurized fluid into a chamber with a downstream wall with an outlet hole in said chamber wall wherein a prodder moves between a sealed and unsealed position in said outlet hole of the chamber wall and wherein a sprung plunger that is upstream of and connected to said prodder and has a annular seal that forms a seal between said plunger and the chamber creating a mobile chamber wall upstream of the downstream wall in said chamber, simultaneously moves between a downstream and an upstream position as the chamber fills with the fluid and then returns to a downstream position as the prodder returns from an unsealed position to a sealed position while the fluid is discharged.

The present disclosure relates to a nozzle for discharging compressed air having a circumferential surface section which extends from a feed end to a discharge end and extends at least partially axially, and an end section produced in one piece, which extends radially inward from the circumferential surface section at the discharge end. In order to allow efficient and targeted compressed air discharge, the present disclosure envisages that a plurality of helical passages extend through the end section, each of which slopes in a tangential direction, at least in some section or sections, and into each of which a first discharge opening for compressed air opens.

Provided is an atomization nozzle including: a nozzle body member having a gas ejection path and a gas ejection port; a liquid nozzle member having a liquid ejection path and a liquid ejection port, a tip portion of the liquid nozzle member being inserted through the gas ejection path; a pattern adjustment groove that produces a swirling flow in the gas ejection path; and a spraying pattern adjustment member having a communication flow path and a blocking portion, where a spraying pattern can be changed by switching between a first position in which the pattern adjustment groove and a gas supply flow path are in communication via the communication flow path and a second position in which the pattern adjustment groove is covered by the blocking portion. Also provided are an atomization device, a spraying device, and a spraying method.

Exhaust nozzles for outflow valves (OFVs) that are usefully employed in aircraft pressurization systems include an upstream solid (e.g., cylindrical) wall section and a downstream solid exhaust wall section fixed to the upstream solid wall section. The downstream solid exhaust wall section includes a circumferential portion defining a series of air intake perforations. A pair of vortex generators may also be provided upstream of the series of air intake perforations. The air intake perforations and optional vortex generators thereby allow air from the ambient pressure environment to be introduced into the boundary layer of pressurized air discharged by the OFV in the interior of the perforated region of the downstream solid exhaust wall section of the nozzle thereby reducing adverse pressure gradients therewithin which in turn results in a more attached air flow and hence less perceived noise.

A nozzle of a fire suppression system includes a housing. Two or more orifices in the housing emit a fire suppression agent. Each of the two or more orifices emits the fire suppression agent in a rotational vortex.

A method of real time optimization of a microwave plasma includes adjusting in real time an injection angle of a swirl gas flow of the microwave plasma, the magnitude of the swirl gas flow of the microwave plasma, or the microwave power applied to the microwave plasma.

Provided is a device for press-inserting an anti-vibration bush having a rubber elastic body formed on an outer periphery of a cylindrical body into an attachment hole formed in a press-insertion object, the device including: a press-insertion portion which moves the anti-vibration bush toward the press-insertion object from an initial position separated from the press-insertion object; a casing which is provided between the initial position and the press-insertion object; and a nozzle which sprays a lubricant in the casing, in which the anti-vibration bush passes through the casing to be press-inserted into the press-insertion object, and in which the nozzle sprays the lubricant to the anti-vibration bush passing through the casing so that the lubricant is coated onto the anti-vibration bush.

A wash nozzle assembly for comprising a cylindrical nozzle body component having a proximal end with a demountable coupling device for engaging a supply of high-speed fluid, and a distal end; a cylindrical nozzle tip component having a proximal end for demountable coupling with the distal end of the cylindrical nozzle body, and a conical distal end, said conical distal end having at least one orifice; at least one O-ring mounted onto the distal end of the cylindrical nozzle body; a swirl plate mounted into a juncture of the cylindrical nozzle body and the cylindrical nozzle tip component, the swirl plate having at least one channel therethrough; and a three-dimensional flow interrupter component housed within the cylindrical nozzle tip component. The wash nozzle assembly can be demountable engaged with an end of coiled tubing for cleaning and washing debris from a wellbore.
