Beschreibung
Zusammenfassung:	fan manufacture, namely main ventilation systems for shafts and mines, mainly gas suction units and, particularly systems for controlling environmental pressure. SUBSTANCE: aerodynamic non-return valve includes body with locking member mounted in it and having aerodynamic profile of wing and non-symmetrical rotation axle. The last is provided with weights mounted on guides with possibility of motion. EFFECT: reduced aerodynamic resistance, less loss of power, enhanced explosion-proof properties. 2 cl, 4 dwg
