ABSTRACT:
A device for introducing CO.sub.2 into a preferably liquid extinguishing medium includes a housing (1) with a feed line (2) for extinguishing fluid, a feed pipe (4), provided with a metering valve (3), for CO.sub.2, as well as an outlet line (5). The housing (1) is aligned with its longitudinal axis vertical; the feed line (2) for extinguishing fluid is connected to the housing at the lower end thereof; the outlet line (5) branches off from the upper end of the housing. The CO.sub.2 feed pipe (4) opens into the housing from above, extends as far as the lower end thereof and is provided at the pipe end with injection fluid (6). The CO.sub.2 is directed in the feed pipe in the opposite flow direction to the extinguishing fluid; the length of the feed pipe between the metering valve (3) and injection fluid (6) is dimensioned such that during operation with the metering valve (3) closed a gas cushion (7) forms on its downstream side.
