Abstract: A screw compressor having screw rotors for compressing a process gas, a pipe bend conducting compressed process gas towards a silencer. The pipe bend at an inlet-side portion comprises a first connecting piece fastening the pipe bend to a pressure port and on an outlet-side portion a second connecting piece for fastening the pipe bend to the silencer. The pipe bend has a flow channel between the connecting pieces defined by an inner wall and an insert that projects into the inlet-side portion of the pipe bend. An outer wall of the insert projecting into the flow channel of the pipe bend and a portion of the inner wall of the pipe bend enclosing this outer wall on the outside delimit a space acting as resonator, coupled to the flow channel of the pipe bend.

Abstract: A muffler for a turbo engine or piston engine, particular a screw compressor, includes a housing (1.1-1.3); a disk arrangement having at least one disk (3, 4, 5) which is fastened to the housing; a pipe arrangement which is fastened to the disk arrangement and which has at least one pipe (2.1, 2.2) for guiding a fluid of the turbo engine or piston engine; and a vibration-damping jacket (9) of dimensionally stable material which at least partially covers the outer side of the housing (2.2). At least one elastic element (3.3, 4.3, 6, 7, 8) is arranged between the pipe arrangement and the housing.
