Pneumatic drive muffler, has pressure sensor that produces warning signal and switches off pneumatic drive when impact pressure within cavity increased due to increased contamination of muffler reaches predetermined limit pressure

摘要

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.
