Abstract
The present invention provides a silencer, which is coupled to a pneumatic device to reduce noise. The silencer (10) of the present invention has a double pipe structure, which includes an inner casing (11), which is coupled to an outlet of the pneumatic device, and an outer casing (12), which is coaxially provided around the inner casing (11). A space (18) is defined between the inner casing and the outer casing. The space communicates with an air guide hole (15), which is formed in one end of the inner casing. Furthermore, an acoustical absorbent (22) is provided in the space (18). Preferably, the acoustical absorbent has a spiral shape. Thus, compressed air, which has passed through the pneumatic device, passes through the acoustical absorbent of the silencer. At this time, almost all noise is absorbed by the acoustical absorbent.
