ATOMIZER FOR A LUBRICANT PRODUCT AND LUBRICATION SYSTEM COMPRISING SAID ATOMIZER
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.
1 . An atomizer of a lubricant product along a spraying axis, comprising:
a first passage of the lubricant product which is centered on the spraying axis,
a nozzle, which is centered on the spraying axis,
a core which is coaxially positioned inside the nozzle,
a second passage for ejecting a first air jet, which is arranged around the first passage along a peripheral direction to the spraying axis, and which, during operation, imparts to the first air jet a helical direction,
wherein
the first passage is defined between the core and the nozzle and is formed with several disconnected passage sections,
the atomizer further comprises a ring which at least partly clasps the core, and
the passage sections of the lubricant product are formed with grooves axially extending on the periphery of the core or inside the ring.
2 . The atomizer according to claim 1 , wherein the passage sections have a radial dimension of less than 0.5 mm.
3 . The atomizer according to claim 1 , wherein the passage sections of the lubricant product are regularly distributed around the spraying axis.
4 . The atomizer according to claim 1 , wherein the passage sections are triangular.
5 . (canceled)
6 . The atomizer according to claim 1 , wherein the atomizer comprises a third passage for ejecting a second air jet, which is positioned between the ring and the nozzle.
7 . The atomizer according to claim 6 , wherein the third passage is tubular so that, during operation, the third passage gives the second air jet an axial direction.
8 . The atomizer according to claim 1 , wherein the second air passage is formed with holes which are regularly distributed around the spraying axis and which, during operation, give the first air jet a direction comprising an axial component and an ortho-radial component to the spraying axis.
9 . The atomizer according to claim 1 , wherein an electrically conducting element positioned in contact with the lubricant product and is powered up during the operation of the atomizer.
10 . A facility for lubricating a part, comprising:
a confinement chamber,
a block for supplying a lubricant product,
an electropneumatic control box, and
at least one atomizer according to claim 1 .
11 . The facility according to claim 10 , wherein the block for supplying a lubricant product is equipped with a valve for interrupting a flow of the lubricant product towards the atomizer at a frequency comprised between 10 and 200 Hz.
