The sound absorber includes a main body (1), a housing component (2) attached thereon and a cap (3) threaded onto the main body. The compressed air exiting from the compressed-air vibrator flows from a first chamber (4) into a second chamber (5) provided with labyrinth-like baffles (7) and from there into a larger third chamber (6). The relieved compressed air then flows outside through an annular outlet slit (8a). Through rotation of the cap (3) there can be varied the cross-section of the outlet slit (8a). The cap (3) thereby also serves as a throttle valve. The sound absorber is insensitive to oil-containing compressed air and, without an auxiliary throttle valve, facilitates a correlatable throttle of the exiting compressed air. |
