Abstract: A self-excited pneumatic oscillator is described which includes a reciprocating hammer member adapted to impact an anvil. The hammer is disposed in a housing structure which includes a porting arrangement. As the hammer moves towards engagement with the anvil, it in sequence opens a discharge port and then an intake port in communication with a source of pressurized air. The space between the front surface of the hammer and an extended housing section which supports the anvil defines an active cavity. The space between the housing and the rear surface of the hammer defines a passive spring cavity. The hammer and these cavities define a system which is acoustically resonant and oscillates at a frequency determined by the dimensions and masses thereof to convert the flow of pressurized air into reciprocating motion of the hammer and provides isolation (minimizing pressure fluctuations) between the oscillator and the air source.
