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 pressure amplifier () is described comprising a housing (), an amplification piston () in the housing () having a high pressure area () in a high pressure chamber () and a low pressure area () in a low pressure chamber (), and a switching valve () having a pressured control valve element having a larger pressure area () and a small pressure area (). Such a pressure amplifier should have a high operating frequency. To this end the valve element () and the amplification piston () are located in a same bore () in the housing ().

Pressure amplifier

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 double acting hydraulic pressure intensifier () is described comprising a housing (), a first piston arrangement () having a first high pressure piston () in a first high pressure chamber () in the housing () and a first low pressure piston () in a first low pressure chamber () of the housing (), a second piston arrangement (), having a second high pressure piston () in a second high pressure chamber () in the housing () and a second low pressure piston () in a second low pressure chamber () in the housing (), and a switching valve () having a valve element (). Such a pressure intensifier should be made compact. To this end the switching valve () is located between the first piston arrangement () and the second piston arrangement ().

Double acting hydraulic pressure intensifier

A pressure amplifier () is described comprising a housing () a low pressure chamber (-), a high pressure chamber (-) and for transmitting means between the low pressure chamber (-) and the high pressure chamber (-). Such a pressure amplifier should have a compact design. To this end the force transmitting means comprise a rotor () arranged in a bore () of the housing (), wherein the rotor () comprises a radially extending low pressure wing () and a radially extending high pressure wing (), the low pressure wing () together with the housing () delimiting the low pressure chamber (-) and the high pressure wing () together with the housing () delimiting the high pressure chamber (-), wherein a supply of fluid into the low pressure chamber (-) causes a rotation of the rotor () and a rotation of the rotor causes a decrease of volume of the high pressure chamber (-).

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.

Hydraulic system

A capacitive transducer having a significantly increased actuation force and improved response time as compared to similar prior art capacitive transducers. In the capacitive transducer of the present invention it is not necessary to balance response time and actuation force or to provide pre-strain to the transducer in a direction of actuation. Additionally, buckling in the capacitive transducer is prevented, or at least substantially reduced, in a simple manner.
