Improvements in patent no. 347,980, relating to improvements introduced in fire extinguishing devices, essentially characterized by the arrangement in the upper base of the valve that gives way to the extinguishing powder of a circular rib provided with a sharp edge, while that around the mouth of the passage a channel is used to house an elastic ring serving as a seat for the valve whose rib is fitted in the elastic mass of the seat making a good closure, also providing the said elastic seat of a skirt peripheral that avoids the formation of cumulative dead angles, at the same time that favors the tightness of the closure.
