PNEUMATIC SHOCK ABSORBER WITH TWO RUBBER CORD CASINGS OF CYLINDER TYPE Russian patent published in 2018 - IPC F16F9/04 

FIELD: machine building.

SUBSTANCE: invention relates to vibration isolation equipment. Pneumatic shock-absorber contains two rubber-cord casing (RCC) of cylinder type, which are under excessive pressure. RCCs are fixed by one side to the bracket, and by the other - to the central support part at an angle α to the horizontal axis to meet each other. Camping rings have an inclination angle β to the horizontal axis, which allows the shells to roll over the inclined surfaces of the clamping rings. RCCs are hermetically connected to the central cavity through which the axis that connects the brackets passes. In the cavity there is an elastic element, which is included in the work with large displacements of the central support part in the radial direction.

EFFECT: effective protection of equipment from external vibrations and shocks, increase of strength, durability, as well as limited movement of equipment relative to the foundation is achieved.
