    摘要: An acoustic filter adapted to be fitted on a pipe for the purpose of absorbing pressure waves. The acoustic filter has a body constituted by a cylinder, an inlet and outlet end, a locking ring fitted in a groove located at the inlet and outlet ends, coupling means within the locking rings for coupling the filter to a pipe. A holder tube fitted with diffuser rings for connecting the coupling means. A deformable bag made from a flexible material is mounted between the inlet and outlet ends, shaped like a cylindrical sleeve and surrounds the holder tube and diffuser rings. The bag defines with an inner wall of the cylinder a chamber for receiving a pressurized gas.
