    Abstract: A percussion device including a shank adaptor, a machine housing that contains a percussion piston that is arranged to carry out a reciprocating movement caused by the pressure from a hydraulic fluid and to strike the shank adaptor when the percussion device is in use. An elastic element is arranged radially outwards from the percussion piston to dampen the recoil from the shank adaptor. The machine housing has an inner surface that faces the percussion piston. The elastic element has an inner surface that faces the percussion piston and an outer surface that faces the inner surface of the machine housing. At least a part of the outer surface of the elastic element directly faces the inner surface of the machine housing.

    Abstract: The present invention relates to a pulse generating device for inducing a shock wave in a tool, wherein the said pulse generating device comprises an impact means (201; 301) for transferring energy to a drill string (202) connected to the said tool, and wherein the energy transfer gives rise to the said shock wave, in which the said energy is mainly constituted by elastic energy stored in the impact means (201; 301) and/or an energy store. The device comprises control means for controlling the interaction of the impact means (201; 301) with the drill string (202), wherein the said control means for controlling the interaction of the impact means (201; 301) with the drill string (202) comprises a motor (207; 307), and wherein the said motor (207; 307) is designed to, through rotation, alternately open ducts for pressurization and depressurization of at least one drive surface (205) acting upon the said impact means. The invention is characterized in that the rotation axis of the said motor (207; 307) is arranged substantially coaxially with the drill string (202).
