FIELD: mechanical engineering.
SUBSTANCE: proposed gas flow noise silencer has housing with inlet and outlet branch pipes. Hollow insert with throttling member installed coaxially with housing and made of porous noise-absorbing material, and cylindrical spring lined with noise-absorbing material and installed between insert and housing and forming screw channel connected with inlet branch pipe. Cylindrical spring is lined with noise-absorbing material in form of plate made of mineral wool on Rockwool type basalt base.
EFFECT: improved efficiency of noise silencing.
