PERCUSSION TOOL Russian patent published in 2015 - IPC B25D17/24 B25D17/06 

FIELD: process engineering.

SUBSTANCE: invention relates to percussion-type tools. This tool comprises working member, reaction force transfer element, first resilient element to shift the latter forward and second resilient element. Second resilient element pushed by reaction force transfer element and deformed with compression lessens reaction to shock when said reaction force transfer element shifts backward at receiving the shock reaction force. Tool working member pressed by user to workpiece, said reaction force transfer element is pushed by tool working member to compress the first resilient element to contact with second resilient element to incompressible state. When said reaction force transfer element takes the shock reaction force at working position and displaces backward in working tool axial direction to deform the second resilient element and to damp the shock reaction force.

EFFECT: decreased overall dimensions of the tool, tool sufficient damping.
