FIELD: machine building. ^ SUBSTANCE: unit of vibration absorption consists of two interconnected pneumatic elements made as closed elastic chambers filled with compressed air. The pneumatic elements are interconnected and connected with a source of compressed air by means of damping channels. The channels are flexible tubes made of elastic material with a calibrated internal cylindrical surface having throttling properties. The system of pneumatic elements or each of them are separately enclosed in a shell of three layers. The outer antifriction layer is made, for example, of woven-wire-cloth containing strong elastic fibres. The middles elastic woven layer is made, for example, of elastic synthetic fibres. The inner layer is made of solid protective material, such as industrial fabric. One of the pneumatic elements is connected to a valve for controlling pressure in the chambers of pneumatic elements, and the other one is to a source of compressed air. ^ EFFECT: increased efficiency of vibration isolation. ^ 2 cl, 4 dwg |
