Abstract
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
