摘要

The device has a trap (5) maintained in an inclined position with respect to a median plane by action of a main counterweight. A main reservoir (19) cooperates with an auxiliary reservoir arranged for being emptied to reconstitute a trap seal only at the end of emptying the reservoir (19). The counterweight cooperates with an auxiliary counterweight (13) so that flushing is carried out by pouring content of the reservoir (19) in a tank.
