ABSTRACT:
The disclosure is directed to a dynamic absorber with pneumatic springs, which absorber is adapted for absorbing a vibration of a machine caused by an excitation force generated in the machine. The dynamic absorber comprises a pair of pneumatic springs disposed to be spaced apart from one another along a preselected spring action line, a weight means supported between the pair of pneumatic springs and capable of vibrating, and a pressurized air pipeline circuit for introducing a pressurized air into the absorber and for exhausting the pressurized air from the absorber. The internal pressure of the pneumatic springs is remotely and adjustably regulated by a pressure regulating valve disposed in the pressurized air pipeline circuit.
