FIELD: engines and pumps.
SUBSTANCE: high-power absorbing packing for fuel assembly incorporates an upper elongated cylindrical housing and a lower elongated cylindrical housing moving in the aforesaid upper housing. Both housings are shifted relative to each other by means of a set of limiting springs constrained by a piston traveling lengthwise, the said piston upward motion being limited by a stop arranged in the upper cylindrical housing. Power imparted to the packing by the adjusting rod is absorbed, mainly, by springs and the piston hydraulic action in the packing.
EFFECT: impact loads originating in emergent cut-out are absorbed without damages.
