Abstract
A pressing device and a method of providing a change of pressure between two pressure states: a low pressure state and a high pressure state of at least 4000 bar, in a pressure vessel of a high pressure isostatic pressing device in which a liquid pressure medium is used for generating the pressure. A first pressure changing device is used for changing the pressure from one of two pressure states to an intermediate pressure state, and a second pressure changing device is used for changing the pressure from the intermediate pressure state to the other one of the two pressure states.
