description FIELD: boring equipment technology. ^ SUBSTANCE: device has body with shell, stepped hammer with head and rod and an anvil, having shared drainage main, distributor system with supply-discharge valve and an accumulator, consisting of spring and piston separating body hollow on force-pumping and accumulating chambers, the latter being in constant connection to shared drainage main. Accumulator is located in the shell in rod area of stepped hammer below the shell. ^ EFFECT: higher operation effectiveness due to removal of resistance to movement of liquid flows from the main and from piston of accumulator by means of transferring of flows intersection point into area of feeding slit of supply-discharge valve. ^ 2 cl, 3 dwg
