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.
