Abstract

931,514. Exhaust silencers. NUQUIP Ltd. March 22, 1960, No. 10033/60. Class 7(2). [Also in Group XXIX] A pneumatic exhaust silencer comprises a cylindrical body 10 of porous material provided with an air inlet 13 and, in its wall, at least one outlet 14 normally sealed by a contractile band 15, the outlet or outlets being opened when the pores of the body become choked and cover the back-pressure in the body to attain a predetermined pressure. The band may be of natural or synthetic rubber or in the form of a spring metal clip. In operation, when the predetermined pressure is reached, due to the silencer becoming choked, the band moves radially away from the wall of the body and at the same time axially along the body so that the outlets 14 are left uncovered when the pressure again returns to normal.
