Abstract
A hydraulic hammer includes an adaptive control unit and a body with openings where hydraulic chambers are formed, those are connected to supercharge mains, and hydraulic chamber connected to the discharge mains, damping chamber and placed in sequence instrument, hammer, valve, accumulator. To the main accumulator an additional chamber for increase or decrease of the volume of accumulator is connected. In the chamber there is a piston, with possibility of equilibrium of pressure of gas of accumulator at one side and liquid pressure from pressure line – at the other side. Motion of the piston depends on change of pressure of liquid in the damping chamber.
