Hydraulic drive for a pressure booster

A hydraulic drive for a pressure booster of a high-pressure apparatus, comprising:

• an electric servo drive effectively connected to an electrical supply operable to be regulated and/or switched by measurement signals;
• a hydraulic pump, which pumps a constant volume of working fluid per revolution, which is driven by the electric servo drive, and
• measuring devices for a pressure and/or a pressure trend of the working fluid and/or a pressure and/or a pressure trend of the high-pressure fluid and/or for a position of a piston in the pressure booster,
• wherein the servo drive is embodied bidirectionally as a reversible motor such that an application of working fluid to the pressure booster is reversible,
• wherein a control of regulating parameters and/or switching parameters of the electrical supply of the servo drive is based on the signals from the measuring devices for the pressure and/or the pressure trend of the working fluid and/or the pressure and/or the pressure trend of the high-pressure fluid and/or for the position of the piston in the pressure booster.
