| Zusammenfassung: | The invention relates to a device for spraying particles of dry ice, particularly for cleaning surfaces, comprising a spray gun (10) with which it is possible to direct a fluid medium driving said particles in a first direction, and a spray nozzle (4) allowing the passage of said driving fluid loaded with said particles, wherein said nozzle (4) comprises a throat (6). According to the invention, said device is configured to direct the fluid medium, loaded with said particles, in at least one other direction upstream of the throat (6) in the flow direction of the fluid medium.
L'invention concerne un dispositif de projection de particules de glace sèche, notamment pour le nettoyage de surfaces, comprenant un pistolet (10), permettant d'orienter d'un fluide moteur entraînant lesdites particules dans une première direction, et une buse (4) de projection, permettant le passage dudit fluide moteur, chargé desdites particules, ladite buse (4) comprenant un col (6). Selon l'invention, ledit dispositif est configuré pour orienter le fluide, chargé desdites particules, dans au moins une autre direction en amont du col (6), selon le sens d'écoulement du fluide moteur. |
