Abstract
A method and apparatus for the evacuation of a gaseous medium especially poisonous and explosive gases from enclosed spaces and alternatively for injecting a medium into said spaces whose method is characterized in that in the case of a closed space provided with one or more air ports equipped with covers a ventilation device is provided in the center of one of said ports which is operated as a turbine using as a source of energy a gas or a fluid preferably to inject an atmospheric medium into said space or to suck air mixed with gas from said space and because a movable tube or duct is lowered to the level of the bottom of the space in order to evacuate the gaseous medium or the mixture of gas and atmospheric medium and alternatively to give entrance to an atmospheric medium.
