Abstract:
To clean an atomizer used for automatic series-production coating of work pieces in a cleaning device provided for this purpose, the outer housing of the atomizer is sprayed by nozzles of the cleaning device, while simultaneously painting and rinsing agents sprayed by the spray head of the atomizer in a short rinsing process are captured and discharged through a pipe section in the interior of the cleaning device. In electrostatic atomizers, voltage equalization between the atomizer and the cleaning device is performed beforehand. Through additional measures, the atomizer can be moved by the handling machine provided for this purpose only from one proper direction towards the cleaning device.
Abstract:
A clog-resistant injector spray nozzle allows relatively unobtrusive insertion through a small access aperture into existing ductwork in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle comprises an easily cleaned and easily replaced straight liquid tube whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube until they both exit the injector, thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.
Abstract:
An air volume booster for sprayers which have a turbine, which when connected to a compressed air source, provide a high volume, low pressure output to a spray gun connected to the sprayer. The booster comprises a supercharger having a shallow cylindrical chamber mounted to the sprayer below the turbine chamber at the intake side thereof, and two inlet ports, one of which is connected to a compressor which provides a source of pressurized air, the other opening to the ambient air. The first inlet port has a venturi incorporated therein and connected to the pressurized air source, which increases the volume of air fed into the supercharger chamber and in turn into the turbine through its intake side for delivery of a substantially increased volume of air at low pressure from the output side of the turbine directed to the spray gun connected thereto.
Abstract:
A high volume, low pressure air system for atomizing a fluid, such as paint, includes, among other things, a variable jet venturi induction pump located within a sealed low pressure air tank for holding a relatively large volume of low pressure air generated by the induction pump which is coupled to a source of compressed air as well as ambient air and having a plurality of outlets which are adapted to be coupled to and feed low pressure air for powering a respective plurality of individual atomizing devices, such as spray guns, with the air tank being located a predetermined distance away from the atomizing devices so that overspray produced thereby is prevented from being fed along with the ambient air into the induction pump. The system also controls the supply of compressed air and can be equipped with a compressed air driven intake fan for turbo charging the ambient air fed to the jet venturi induction pump.
Abstract:
The nozzle device (10) of the present invention is provided with a columnar body (12) in which a water inlet portion (25) and two or more spray holes (16) are formed, a hollow rotational nozzle (30) that rotatably interlocks with the spray hole (16) and protrudes to the ejection side, and a cylindrical rotational ring (50) rotatably placed over the outer side of the body (12), wherein the rotating shaft of the rotational nozzle (30) disposed in the body (12) slopes outward in the radial direction of the nozzle device (10) toward the ejection side, the axis of a nozzle hole (46) of the distal end part (44) of the rotational nozzle (30) slopes toward the rotating shaft of the rotational nozzle (30), and a ring gear (54) formed on the internal peripheral surface of the rotational ring (50) and a gear (42) formed on a protrusion (36) of the rotational nozzle (30) mesh together. The rotating ring is made to rotate by the configuration, thereby allowing the discharge angle of a fluid ejected from the nozzle device to be easily modified.

Abstract:
A clog-resistant injector spray nozzle (200) allows relatively unobstrusive insertion through a small access aperture (120) into existing ductwork (110) in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle (200) comprises an easily cleaned and easily replaced straight liquid tube(365) whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube (365) until they both exit the injector (200), thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.
