CONSUMABLE DAMPER WITH COLLAPSING ELEMENTS Russian patent published in 2014 - IPC F16F7/12 

FIELD: machine building.

SUBSTANCE: damper comprises a rod with a stop in the form of a round plate attached rigidly to its top perpendicular to its axis. A damping base is attached with screws to the lower part of the stop. A bushing made in the form of a truncated cone is attached rigidly to the damping base coaxially to the rod. The lower base of the truncated cone is connected with the damping base. A consumable element made in the form of a bushing from fragile collapsible material like porcelain abuts the upper base of the truncated cone. The above bushing is pressed from beneath with bush-type gripping element provided with grooves for securing a resilient portion made in the form of a conical spring. The upper base of the conical spring faces the bush-type gripping element. The lower base of the conical spring is secured in the grooves of the damping base by means of cast polyurethane. The bush-type gripping element is secured by means of latches installed on the rod surface.

EFFECT: increased reliability of actuation of explosion-proof devices.
