VIBRATION-ISOLATING DEVICE Russian patent published in 2020 - IPC F16F15/23 F16F9/04 

FIELD: protective devices.

SUBSTANCE: invention relates to active vibration protection devices of large-size objects. Telescopic guiding device (2) is made in the form of oppositely directed external (3) and internal (4) cups with rubber-cord shell (5) installed between them and centering elements (6, 7). Elastic element (1) is made in the form of pneumatic vibration isolators, uniformly located around outer sleeve (3), each of which consists of housing (12), plunger (13) and rubber-cord shell (14) between them. Housing (12) is hinged to support plate installed on protected object. Plunger (13) is hingedly connected to plates (17) installed on the bases of base projections (18). At the end of inner sleeve (4) of the telescopic guide device (2) there is sealing partition (20) with a valve electromagnetic device (21). On plungers (13) of all pneumatic vibration isolators there are sealing walls (24) with valve electromagnetic devices (25). Rubber-cord casing (14) of each pneumatic vibration isolator of the elastic element is connected by means of a valve electromagnetic device (25) to a separate source of compressed air (27).

EFFECT: improved damping properties and reduced vibration conductivity of the device.
