VIBRATION ISOLATION SUPPORT Russian patent published in 2022 - IPC F16F13/16 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering. The vibration isolating support contains a common housing, in which the working and compensating chambers are located, filled with damping fluid and separated by a dividing wall with at least one internal cavity and throttle channels for bypassing the damping fluid between the working and compensating chambers, the working chamber is limited by an elastic element with a fixed in it by the mechanism of fastening of the suspension object, the compensation chamber is limited by the retaining membrane. The support is also provided with an external locking body rigidly fixed to the common body. The elastic element is made in the form of an elastic working element and is located in the outer fixing case. The suspension object fastening mechanism is made in the form of a fastening rod and is fixed in the elastic working element with the possibility of simultaneous movement with the elastic working element due to its deformation under the action of the load. The inner cavity of the working chamber is made of toroidal shape. The separating partition is made in the form of a cylindrical annular part with an additional elastic membrane fixed in the center of its cross section, an air supply hole is made in the common body with the possibility of regulating the pressure in the working chamber.

EFFECT: reduced vibration and acoustic loading of the sprung object.
