ABSTRACT:
The phonic deadening device comprises a cylindrical sleeve (5) with double walls, made of an elastic material and the axial traversing opening of which serves for the passage of the flux of the liquid. Both walls of this sleeve define between them an empty annular space (6), which is closed in a tight manner by an annular sealing element (7). This element further serves to position and to maintain the sleeve in a service position in the conduit.
