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.
