Therefore, the quick extension of the ram. The diaphragm accumulator, due to the small mass of the diaphragm, when the ram stops moving by the tool supported on the rock, ensures the growth of the rope in the ram working chamber proportional to the mass and speed of the atomized stream contained in the conduit between the battery and roboose chamber * From French Patent Specification No. 2,068,026 a Nydraullouna hammer containing an oyllnder in which a piston is deposited is known Zones on a piston drag * The space inside the cylinder is divided by a piston into two chambers: One is filled with oleose and the other with compressed gas * The piston drag is connected to the strand organ of the hydraulic hammer and controls the ram's thrust * The piston has a mass many times less than the mass the hammer head, and the piston's mass does not contribute to the compaction of the working axle in ^ n * fn-ole the hammer's impact on the crushed rock * The hydraulic hammer machine, according to the invention, is equipped with a piston accumulator connected hydraulically with a plate device * The weight of the accumulator piston mass is close to the size of the mass of the machine ram * Preferably, in order to obtain such a smooth mass, the accumulator piston is filled with an olesque metal * V impact maonanism of the machine, the increase in glare in the working chamber is proportional to the mass and speed of the spreading stream of the axle and to the mass and speed of the accumulator piston separating compressed gas from oieozy robooza * Cleoz robooza stroke mechanism u / which is usually mineral oil / It is not very elastic * and the kinetic energy of the battery piston performs the work of compressing the axis closed between the battery piston and the lamella stopped by the working tool on the rock cut * causing an additional increase in glare * 2 129 069 The machine according to the invention is presented in an example is in the picture * Pump 1 delivers the working axle through a non-return valve 2 to a piston accumulator 3 having a piston 4 on one side, a chamber 5 filled with robo oleose * and on the other side a chamber 6 filled with air or nitrogen * Chamber 6 is charged with gas once through a known gas valve return * Minor losses of gas9 related to the drop in the gas level, do not change the working conditions of the percussion mechanism * To obtain the appropriate weight * the piston is filled with heavy metal, e.g. * lead * Separate 7 laoses of the accumulator 3 * working chamber 8 ram 9t which under the influence of pressure gains speed and hits the corner in the con- The tines 10 supported on the rock being cut 11 * The suspended movement of the hammer causes the occurrence of a water hammer in the working chamber 8 * The amount of glare of the water hammer is proportional to the mass and speed of the working stream * as well as the mass and speed of the accumulator piston * Patent claims 1 * Hydraulic impact machine having a bladder and a battery with a piston that separates the working liquid chamber from the compressed gas chamber inside the battery, characterized by the fact that the piston / k / battery / 3 / has a mass similar to the weight of the battery / 9 /. 2 * Hydraulic impact machine according to claim 1 * characterized by * the interior of the piston / k / is filled with heavy metal * Pracownia Poligraficzna UP PRL.
