Apparatus for generating impulse-dynamic process forces

An apparatus for generating impulse-dynamic process forces, comprising:

• a pressure chamber in which a pressurised hydraulic medium is arranged;
• means for temporarily increasing the pressure of the hydraulic medium located in the pressure chamber;
• a connecting chamber arranged downstream of the pressure chamber and connected thereto;
• a bolt chamber arranged downstream of the connecting chamber and connected thereto;
• a stepped piston arranged so as to be displaceable in the connecting chamber, which piston has a valve body for closing an orifice connecting the pressure chamber to the connecting chamber, and a piston portion facing the bolt chamber, by means of which piston portion a transmission space of the connecting chamber between the piston portion and the bolt chamber is sealed with respect to the side of the connecting chamber remote from the bolt chamber, the transmission space having a pressurised hydraulic medium arranged therein;
• and
• an impact bolt arranged so to be displaceable in the bolt chamber,
• wherein the impact bolt has a first bolt portion with a larger cross-section and a second bolt portion with a smaller cross-section, the first bolt portion sealing an interior space of the bolt chamber that surrounds the second bolt portion with respect to the connecting chamber, and there is connected to the bolt chamber at least one pressure reservoir containing a pressurised pressure medium, which the at least one pressure reservoir is in communicating connection via a connection port arranged in the bolt chamber with the interior space of the bolt chamber.
