Abstract
An apparatus for generating impulse-dynamic process forces includes a pressure chamber, a connecting chamber and a bolt chamber. The pressure chamber includes a plunger arranged to be pushed into the pressure chamber for compression of a hydraulic medium located therein. In the connecting chamber there is displaceably arranged a stepped piston which has a valve body for closing an orifice connecting the pressure chamber to the connecting chamber. In the bolt chamber there is located a displaceable impact bolt which has a first bolt portion and a second bolt portion. The first bolt portion seals an interior space of the bolt chamber that surrounds the second bolt portion. Connected to the bolt chamber there is at least one pressure reservoir containing pressurised pressure medium, which pressure reservoir is in communicating connection via a connection port with the interior space of the bolt chamber.
