Abstract

The muffler has a casing body (2) linked with an exhaust port of a control valve. The body exhibits a porous, air-permeable base structure and includes a cavity. The casing body has a pressure sensor (6), pressure sensor that produces warning signal and switches off pneumatic drive when impact pressure within cavity increased due to increased contamination of muffler reaches a predetermined limit pressure.
