Abstract
A hydraulically operated setting device with a hydraulic aggregate as well as a joining method for connecting at least two components with the help of the hydraulically operated setting device is described. The cycle times compared to conventional joining methods are reduced through the targeted use of volume flows of hydraulic fluid in the prestroke chamber and the return-stroke chamber of the piston in connection with the plunger and the hold-down device chamber in connection with the plunge piston and the hold-down device.
