The pressure generator (1) has a pneumatic piston that is connected with a hydraulic piston. The pneumatic piston is moved by a control device so that pressure is produced by the reciprocating movement of the hydraulic piston in a hydraulic region. The hydraulic region is provided with a relief valve and a quick connector (8) which is connected with a hydraulic passage for a hydraulic tool. The control device is provided with a piston control element. |
