Abstract: The invention relates to a sprayer, comprising an air guiding element and means for fastening the air guiding element on a fixed member of the sprayer. The fastening means comprise at least one magnetic attraction means mounted on a first component from among the air guiding element and the fixed member and at least one part made from a ferromagnetic material, which is intended to cooperate with the magnetic attraction means and which is mounted on or formed by the other component from among the air guiding element and the fixed element.

Abstract: A generator usable in an explosive atmosphere zone, and having a power greater than or equal to 8 Watts, preferably greater than 10 Watts, and an assembly including an electrostatic sprayer for a coating product and the generator.

Abstract: A spray nozzle for electrostatic spraying of a coating product including a needle forming a mobile shutter of a valve for controlling the spraying, which is positioned in a recess of a barrel of the nozzle. The recess defines a surface for guiding the axial translation of the needle along a longitudinal axis of the recess. The needle includes a front shaped for abutting a seat to obstruct a duct for flow of the coating product, a rear portion which interacts with means for controlling the translation of the needle and a central portion comprised between the front end and the rear portion, while a high-voltage unit included in the nozzle is capable of applying a high-voltage to the front end of the needle. A raised portion provided on the central portion of the needle, inside the recess, can increase the electric creepage distance along the central portion.

Abstract: An apparatus for electrostatically spraying a coating product. The apparatus includes a sprayer with first and second pipes which control the flow of the coating product. Air is controlled by at least one valve. The sprayer includes a device for controlling the opening/closing of the valve, a high voltage unit. A generator includes a module for controlling power supplied to the high voltage unit. The sprayer includes a first sensor suitable for detecting the position of a shutter of the valve relative to a seat and for outputting a signal used by the control module to control the power supplied to the high voltage unit, and a second sensor suitable for detecting the position of a switch positioned on the spray gun and for outputting a signal used by the control module to control the power supply of the high voltage unit.

Abstract: This method serves to manufacture a coating gun, this gun comprising an injector for spraying a round jet along a spray axis and a cap arranged coaxially around the injector, this cap being provided to form an air knife around the jet. This method comprises a step consisting of sizing an axial excess dimension of the injector relative to the cap based on the diameter of the injector. The coating gun comprises an injector for spraying a round jet along a spray axis, a cap arranged coaxially around the injector, provided to form an air knife around the jet. The injector protrudes axially relative to the cap and the axial excess dimension of the injector relative to the cap can be adjusted between a minimum value and a maximum value that are determined based on the diameter of the injector.

Abstract: This atomizer makes it possible to spray a lubricant product along a spraying axis and comprises a first passage for the product which is centered on the spraying axis, a nozzle which is centered on the spraying axis, and a core which is disposed coaxially inside the nozzle. The atomizer also comprises a second passage for ejecting a first jet of air, which is arranged around the first passage in a peripheral direction with respect to the spraying axis and which, in operation, confers a helical direction on the first jet of air. In addition, the first passage is defined between the core and the nozzle and is formed by a plurality of separate passage sections.
