Abstract

A hydraulic pressure boosting unit (11) is used in particular in a press operating according to the high inner pressure extrusion process. The hydraulic pressure boosting unit has a docking cylinder (10) with a docking piston that slides in a first cylinder chamber (15) and a docking piston rod (26) secured to the docking piston projects outwards through a housing head (20). The hydraulic pressure boosting unit has a pressure booster (11) with a primary piston (40) located in a second cylinder chamber (16) coaxial to the first cylinder chamber and separated from the first cylinder chamber by a housing bottom (17) and with a secondary piston (41) that plunges into a central axial bore (28) of the docking piston and docking piston rod. In order to generate high forces with the docking cylinder, only one side of the docking piston has a piston rod, namely the docking piston rod.
