Abstract
Improvements in hydraulic hammers. The improvements are characterised by an assembly of cylinder and surrounding casing which form a unit, with end guiding and joining covers, attached at one end to a pressure accumulator body, at the upper end of its body having distributor valves and the cylinder and surrounding casing assembly is attached at its other end to a body which receives the end of the percussion element of the hammer and an automatic control valve of the start-stop action in combination with the axial positions of the percussion element itself.
