FIELD: filling stations. SUBSTANCE: station contains case and connecting communications with sealed interwall space, and pressure control equipment. Interwall space of the case and the communications are filled up with inter gas of pressure Patm<P<Pc,, where Patm is atmosphere pressure, P is interwall pressure, Pc is pressure of the case. Each part of the communications is limited on it ends with flanges and couplings: deaf or control with passages. Space between flanges or coupling members is connected to the interwall space of the communications. Ended parts of communications are provided with lens bend. EFFECT: enhanced efficiency. 2 cl, 2 dwg
