Abstract

A recoil damper for a percussion tool (1) which is movable to-and-fro between an impact face (3) and a recoil receiving face (4) and which is driven against the impact face so as to deliver its kinetic energy by impact effect to the impact face. The invention is characterized by having at least one additional mass (6) which is movable in relation to the percussion tool (1) and which is connected to the percussion tool by at least one resilient member (7), the resiliency of the resilient member being chosen so that the kinetic energy of the mass (6) cooperates with that of the percussion tool at the impact of the percussion tool against the impact face (3) while the kinetic energy of the mass (6) is directed opposite to that of the percussion tool at the impact of the percussion tool against the recoil receiving face (4). By this arrangement the recoil force performs a useful work in that the recoil force is turned at the impact of the percussion tool against the recoil receiving face and contributes to setting the mass (6) into operation which coincides with that of the percussion tool when the last-mentioned strikes against the impact face (3). By that the operating force of the percussion tool is improved.
