摘要： Gasodynamic ventilation device consisting of a prime ejection channel provided with a nozzle for the introduction of the operative fluid and a secondary ejection channel mounted coaxially with a prime ejection channel provided at the upstream end with an admission inlet for the ambient air provided with a silencing screen. The primary and secondary channels are provided with vanes so that the two channels are separated by a section which constitutes the inlet for the admission of ambient air.In a first modified construction of the secondary channel is provided a shield griller in a second variant the secondary channel is provided with automatic obturating members consisting of a front wall being constructed as a flap and two lateral walls, the entire obturator being pivotally mounted.
