摘要

Device for introducing a gas (G) into a liquid (F) comprises a liquid line (8) and a gas line (4) both connected to a differential pressure regulator (5) which has a first active surface (22) impinged by the liquid and a second active surface (23) impinged by the gas. One part of the section (32) of the liquid line is formed between the differential pressure regulator and a valve (18) as flow resistance.
