SINGLE ACTION SHOCK ABSORBER WITH BREAKABLE ELEMENTS Russian patent published in 2018 - IPC F16F7/12 E04B1/92 

FIELD: protective devices.

SUBSTANCE: invention relates to protective devices, for example shock absorbers, used in explosive facilities. Single action shock absorber with breakable elements contains a body, elastic and damping elements, additionally contains a rod, in the upper part of which, perpendicular to its axis, a fixed stop in the form of a circular plate is rigidly fixed, to the lower part of which the damping base is fastened with screws, and co-axially with the rod a bushing made in the form of a truncated cone is rigidly fixed to the damping base. Truncated cone lower base is connected to the base, and the single action element is supported against truncated cone upper base, made in the form of a hub of brittle, collapsing material, for example porcelain, which is pressed from below by a hub-type clamping element with grooves for fixing an elastic part in the form of a conical spring turned by its upper base towards the bushing-type clamping element. Conical spring lower base is fixed in the grooves of the damping base by means of injection polyurethane, wherein fixing of the bushing-type clamping element is implemented by means of latches mounted on the surface of the rod. Inside the bushing, made in the form of a truncated cone, wherein the bottom base of the truncated cone being connected to the base, and in the of the truncated cone upper base a single-action element is pressed against, an elastic conical element with an outer surface congruent and equidistant to the sleeve is located axially symmetric. Rod is made resiliently damping, consisting of co-axially arranged bushings and rods, wherein the bushings are made of an elastic material, and the rods of a vibration damping material, for example polyurethane.

EFFECT: invention increases reliability of operation of explosion-proof devices at emergency explosion at site.
