A fog injection nozzle able to generate a swirling cone of fog. The nozzle includes an internal cavity into which a pressurized liquid and a pressurized gas are introduced. The pressurized liquid is introduced into the cavity via a central axial duct of a cylindrical block and the pressurized gas is introduced into the cavity via a plurality of axial through holes disposed about the central axial duct. The axial through holes and radial arms are arranged such that a mixture of the liquid and gas inside the cavity is asymmetrically deflected by the radial arms to cause a swirling tangential component to appear in the conical flow of fog discharged from the nozzle.

A static spray mixer for mixing and spraying two flowable components includes a tubular mixer housing extending in the direction of a longitudinal axis up to a distal end with an outlet opening, having one mixing element arranged in the mixer housing for mixing the components and having an atomization sleeve with an inner surface surrounding the mixer housing in an end region. The atomization sleeve has an inlet channel for a pressurized atomization medium. A plurality of grooves is in the outer surface of the mixer housing or in the inner surface of the atomization sleeve and extend toward the distal end and form separate flow channels between the atomization sleeve and the mixer housing through which the atomization medium flows from the inlet channel of the atomization sleeve to the distal end of the mixer housing. The inlet channel is arranged asymmetrically with respect to the longitudinal axis.

The present disclosure provides an electrostatic nozzle and a controllable jet minimal quantity lubrication (MQL) grinding system. The electrostatic nozzle comprises a nozzle core; an upper nozzle body is connected above the nozzle core; a free space is formed between the upper nozzle body and the nozzle core for storing compressed air and reducing pressure; a lower nozzle body is connected below the nozzle core; a gas-liquid mixing chamber, an acceleration chamber and a nozzle outlet are sequentially arranged inside the nozzle core from top to bottom; and micro-bulges are uniformly distributed on an inner wall of the acceleration chamber.

A nozzle includes a housing having an inner chamber, a first opening connected to the inner chamber, and a second opening connected to the inner chamber, and a solid, partially conical, plug in the second opening, the solid plug configured to leave a slit around the plug connected to the inner chamber, and the plug extending beyond an end of the housing.

The present invention relates to a liquid chemical sprayer includes: a nozzle cap which is rotatably assembled and installed in place at a rotation guide of a body; a nozzle head; a nozzle is formed at a front end of a nozzle pipe formed extending a predetermined length toward the front, and a guide plate is formed protruding to be assembled to a guide rail formed at a neck capable of operating forward and backward; a valve body formed in a cylindrical shape; a valve housing formed in a cylindrical structure fixedly installed at a rear of the nozzle head and forming a valve seat at an inner portion; and a motor housing faced and assembled with the rear of the valve housing so that the rear thereof is maintained in a fixed state, in which an air blowing module is installed.

Disclosed is a method for disinfecting and cleaning to prevent contamination of a passenger vehicle, characterized in that it includes the following operations: —installing at least one filter and condenser in the ventilation circuit; creating a swirling vortex of a disinfectant liquid by a gas referred to as a driving gas; spraying the swirling mixture created onto the clothing and luggage of passengers before they enter the passenger compartment; and spraying the mixture created onto the solid surfaces and/or into the air of the passenger compartment to be disinfected. Also disclosed is a device for implementing the method.

A spray nozzle for spraying material includes an outlet, a mixing section, an inlet for the material, and a buffer space for pressurized gas. The mixing section is in fluid communication with the outlet. The inlet is in fluid communication with the mixing section. The buffer space is in fluid communication with the mixing section via two or more separate gas supply channels. The inlet comprises a separating wall configured to divide a flow of material to be sprayed into two separate flow passages prior to entry into the mixing section.

A swirler-ferrule assembly includes a radial swirler, a ferrule, a fuel nozzle, and a surface feature. The radial swirler includes a primary swirler vane having a primary air passage and a secondary swirler vane having a secondary air passage. The ferrule may be connected to the radial swirler. The surface feature may be located on the primary swirler vane and/or the ferrule. The surface feature may be configured to direct an air flow through the primary air passage away from a recirculation zone located upstream of the primary swirler vane. The surface feature has a trailing end and a distal end, and the fuel nozzle is axially aligned with the trailing end of the surface feature or is located axially downstream of the trailing end of the surface feature. The surface feature may have a plurality of grooves.
