An airbrush that sprays liquid in a mist form. A supply of a compressed air and a supply of the spray liquid can be controlled at the same time only using a spray button included in a spray head. Accordingly, a loss of the spray liquid can be minimized, the airbrush can be maintained clean, and usability of the airbrush can be enhanced.

A nozzle device includes a first passage, a second passage, and a first ambient valve clapper. The first passage includes a first intake and a first outlet. The second passage includes a second intake and a second outlet. The first ambient valve clapper is configured to control entry of fluid into the second passage through the second intake. The fluid is pumped to enter the first passage through the first intake to form a first negative pressure zone next to the first outlet, and the first ambient valve clapper is opened via a pressure difference between the first negative pressure zone and the surrounding of the nozzle device, allowing the fluid to flow into the second passage.

The invention is a dual auto hydrant configured to interface independent pressurized water and compressed air sources with snowmaking equipment, such as a snowmaking gun and methods of using same.

This manual gun (2) for applying a coating product comprises a high voltage unit (42), designed for electrostatically charge the coating product at a voltage/flow rate characteristic when it is supplied with electric power, and adjustment means (16), for selecting, from among several pre-adjusted voltage/current characteristics, the voltage/current characteristic according to which the product is electrostatically charged. This gun also comprises a control member (10), which is maneuverable between an inactive configuration, where it opposes the application of the coating product and wherein the high voltage unit (42) is not supplied with electric power, and an active configuration, wherein it does not oppose the application of the coating product and wherein the high voltage unit is supplied with electric power. The adjustment means (16) comprise control buttons, giving the possibility of manually adjusting the flow rate of coating product applied by the gun when the control member (10) is in an active configuration and of selecting the voltage/current characteristic when the control member is in an inactive configuration.

In accordance with an example embodiment, there is disclosed herein a sprayer operable to dispense fluid from a fluid reservoir, such as a paint reservoir. The sprayer comprises a rechargeable battery pack that can be employed to provide power to a pump. The pump provides air to a nozzle assembly that is mixed with fluid from the fluid reservoir and dispensed via the nozzle assembly. In particular embodiments, the nozzle assembly comprises a disposable tip insert.

A mixing nozzle includes a first connector, a second connector, a first channel and a second channel, where a first end of the first channel is connected to the first connector, and a second end of the first channel is provided with a spraying opening in communication with the first channel; a first end of the second channel is connected to the second connector, and a second end of the second channel is in through connection with the first channel; the first connector is configured to introduce a first fluid into the first channel, and the second connector is configured to introduce a second fluid into the second channel; and a length of the second channel is less than a length of the first channel.

A foam spray can comprises a motor pump, a foaming tube and a nozzle. The motor pump can be used to suck air and solution and pump out the liquid-gas mixture. One end of the foaming tube is connected to the motor pump for transmitting the liquid-gas mixture pumped by the motor pump and fully mixing the air with the solution to produce foam. The nozzle is connected to the other end of the foaming tube to spray foam. The length of the foaming tube is between 10 to 500 cm, the tube inner diameter is between 0.8 to 20 mm, and the pressure of the liquid-gas mixture in the tube is between 8 to 32 PSI, thereby to provide sufficient time, space and conditions for the mixing of the air and the solution in the foaming tube to fully mix the air and the solution, and then to spray abundant foam from the nozzle.

A sprayer nozzle assembly includes a control valve configured to control a flow rate of agricultural product according to a duty cycle having valve open and valve closed positions. The assembly includes a sprayer tip having a tip orifice for spraying the agricultural product. A throttled interface duct interconnects the control valve and the sprayer tip. The throttled interface duct includes an interface duct profile. The interface duct profile is configured to decrease a flow characteristic of the agricultural product while the control valve is in the valve closed position.

The present invention relates to a spraying vessel and a valve assembly comprising the same, the spraying vessel comprising: a housing provided with an upper sealing cap for sealing an upper portion and a receiving space for receiving contents; a mount cup, mounted on the upper sealing cap, having a through hole formed in a central portion thereof; a stem housing provided with a mounting portion, mounted to the mount cup, having a hollow portion formed therein, and a communication flow path for making the hollow portion be in communication with the receiving space; a valve stem which is installed to pass through the through hole and slide in the hollow portion, and is provided with an orifice being configured to selectively communicate with the hollow portion by a sliding motion; and a flow path blocking valve formed to block an inlet of the communication flow path.
