Mixer and method for interverting such a mixer

摘要

Mixer (1) comprising: a tubular body (2); a first feed (5); a second feed (6); and an internal assembly which comprises: a primary module (13), comprising a primary inlet (21) and a mixer (17), and a secondary module (15) comprising a secondary inlet (78) and a regulator (56). According to the invention, the internal assembly is configured to transition between: a direct configuration in which the primary module is mounted within the tubular body in such a way that the primary inlet is connected to the first feed, whereas the secondary module is mounted within the tubular body in such a way that the secondary inlet is connected to the second feed; and an indirect configuration, in which the primary module is mounted in such a way that the primary inlet is connected to the second feed whereas the secondary module is mounted in such a way that the secondary inlet is connected to the first feed. According to the invention, the internal assembly comprises a pair of collars (38, 84) delimiting between them an intake volume (39, 86) into which either the primary inlet or the secondary inlet opens and into which either the first feed or the second feed opens.
