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 ().

Hydraulic pressure amplifier arrangement

A hydraulic pressure intensifier () is described comprising a housing () having a low pressure chamber () and a high pressure chamber (), force transmitting means () between the low pressure chamber () and the high pressure chamber (), and a switching valve () connecting the low pressure chamber () to a first pressure or to a second pressure different from the first pressure. It is intended to have a large volume on the high pressure side of the pressure intensifier. To this end the switching valve () is controlled by a pilot valve

Hydraulic pressure intensifier

A hydraulic system () is provided comprising a pressure source (), an output (), and a pressure booster () arranged between the pressure source () and the output (). The operational possibilities of such a system should be extended. To this end inactivating means are provided inactivating or activating said pressure booster.
