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 (), an intensifier section () having a high pressure piston () in a high pressure cylinder (), a low pressure piston () in a low pressure cylinder () and connected to the high pressure piston (), and a control valve () controlling a pressure in the low pressure cylinder (), wherein the control valve () comprises a hydraulically actuated valve element (). Such a pressure amplifier arrangement should have a good operational behavior in a cost effective manner. To this end the control valve () comprises spring meansacting on the valve element () in a direction towards a starting position of the control valve.
