Abstract

Oil-dynamic percussion machine having a body (1) in which there are a piston (3) which transforms the hydraulic power of the feeding circuit in mechanical power, a tool (5) that transfers the mechanical power to produce the demolition work, a Nitrogen-filled high pressure hydraulic accumulator (2) having the function of storing the hydraulic power supplied by the feeding circuit and characterised by a modulator slide valve (4) that keeps the operating pressure at a constant value; this mechanism controls the motion of the piston, his active displacement and the oil inlet and discharge control ports (19, 11).
