ABSTRACT:
A noise suppression assembly including a retainer having (1) a retainer body defining a central cavity therein, (2) a base flange extending outwardly from the retainer body, and (3) a fluid channel defined therein. The noise suppression assembly further includes a flow control member having a central passage through which the flow of water advances, the central passage of the flow control member being offset from the fluid channel of the retainer. Moreover, the noise suppression assembly also includes a suppresser having (1) a suppresser body, (2) a bullet secured to the suppresser body, and (3) a hole defined therein through which the flow of water advances, the hole of the suppresser being offset from the central passage of the flow control member, and further the bullet being aligned with the central passage of the flow control member. The base flange of the retainer has a peripheral edge with the fluid channel being spaced apart therefrom. Moreover, the retainer is configured so as to create a reverse flow of water which opposes the flow of water entering the fluid channel thereby reducing the velocity of the flow of water advancing therethrough.
