ABSTRACT:
The apparatus (1e, 1f) according to the invention has a storage tank (5) which is or can be filled with an active substance (3), a pyrotechnic charge (6; 39) in a first end region (9) of the storage tank (5), a cartridge-case base (13) which can be driven by propellant gases of the fired charge (6; 39) in order to drive the active substance (3) out, and has a unit (7) for atomizing the active substance (3) being driven out, and at least one sensor (35a; 35b) which interacts with the charge (6; 39) in order to initiate the latter. The atomizer unit (7) is formed as an atomizer pipe (7) having a plurality of outlet nozzles (15) in the pipe casing in order to fill a spatial region (14) with a mist of the material of the active substance (3). One (18) of the ends of the atomizer pipe (7) is arranged in a second tank end region (19), facing away from the first and extending from the latter. The apparatus is distinguished by a compact and economical configuration with good automatic filling of a space with mist.The apparatus can be used on its own or in a plurality in a parallel arrangement and also in a series arrangement for the protection of an object, be it firefighting or driving away unauthorized persons.
