Abstract
An apparatus for contactless sealing of an opening against emerging or entering gas employs at least one barrier gas jet which is divided in the vicinity of its longitudinal axis. In the two sub-jets adjoining the dividing plane two different gases flow out, the concentration of the two gases changes abruptly at said dividing and separating plane so that a very reliable sealing is achieved.
