Abstract

La présente invention concerne un dispositif d'évacuation de gaz comportant une conduite par laquelle est conduit le gaz à évacuer. Selon l'invention, cette conduit (2, 3, 6) comporte au moins une zone se présentant sous la forme d'un tube de Venturi. En l'occurrence, la conduite (2, 3, 6) comporte de préférence au moins une zone qui se situe sensiblement à l'horizontale (3) et qui se présente sous la forme d'un tube de Venturi (4).
