Abstract

Inventia se refera la un ventilator pneumatic fara piese în miscare utilizat în medii grizutoase. Ventilatorul, conform inventiei, este alcatuit dintr-o carcasa prevazuta cu unul sau doua stuturi de admisie a aerului comprimat si un spatiu de egalizare a presiunii închis de un inel. Pe partea interioara a inelului sînt montate palete radiale prevazute cu fante de dirijare a aerului. Torsionarea paletelor si înclinarea fantelor conduc la formarea unui turbion care antreneaza aerul din zona plaletelor.The invention relates to a pneumatic fan without moving parts used in grizzly environments. According to the invention, the fan consists of a housing provided with one or two compressed air inlets and a pressure equalizer enclosed by a ring. On the inner side of the ring are mounted radial blades provided with air guiding slots. Torsion of the blades and sloping of the slots leads to the formation of a turbine that trains the air in the plateau area.
