FIELD: machine building.
SUBSTANCE: vibration absorption device includes a housing of an arbitrary shape, for example cylindrical, which is tightly closed with an elastic diaphragm. Pneumatic elements made in the form of closed elastic cavities are arranged in the housing and connected to each other. Cavities of the pneumatic elements are filled with compressed air and connected to each other with damping elements. A compressed air source is connected to one of the pneumatic elements, and a control valve of pressure in cavities of pneumatic elements is connected to the other one.
EFFECT: higher vibration isolation efficiency.
