Abstract
A hydraulic pressure amplifier arrangement () is described comprising a supply port (A), a pressure outlet (A) connected to the supply port via check valve means (), a tank port (B), an intensifier section () having a high pressure piston () in a high pressure cylinder () which is connected to the pressure outlet (A), a low pressure piston () in a low pressure cylinder () and connected to the high pressure piston (), an intermediate space () between the high pressure piston () and the low pressure piston (), a control valve () controlling a pressure in the low pressure cylinder (), and a feeder arrangement of the intensifier section () including an input connection () connected to the supply port (A) and a return connection () connected to the tank port (B). Such a pressure amplifier arrangement should have a simple construction. To this end the feeder arrangement () comprises throttling means ().
