Abstract (en)
[origin: DE10232291A1] A housing (11) contains a chamber (12) in the wall of which is an opening (13) and which is located to the side of a gas-flow (14). A deflector (15)is adjustably positioned at the opening and., in a first position, conveys the gas flow flowing past the opening at least partly into the chamber where the gas is condensed. In a second position, the gas flow from the chamber leads into the gas flow so as to remove the tension of the gas
