ABSTRACT:
A combined sound damper and oil trap for compressed air apparatus comprising an oil trap having a hose or tube (5) which is directly connected to the compressed air apparatus and which at the outer end thereof encloses a scraper sleeve (7), whereby a radial space is formed between the scraper sleeve (7) and the hose or tube. The hose or tube is connected to an oil collector housing (1) whereas the scraper sleeve (7) is connected to a pressure chamber (2) which in turn directly communicates with a filter housing (3) containing a sound damper. The said sound damper comprises both a diffusor plate (11) provided between the pressure chamber and the filter housing (3) and a filter (12) which is mounted at the outlet end of the filter housing. The diffusor plate (11) provides a damping of low frequency noise and a substantially even distribution of the outlet air over the entire diffusor plate, and the filter (12) provides both a separation of oil mist from the outlet air and a damping of high frequency noise.
