Abstract
For detecting leakage past a high pressure seal which seals a space in which a high pressure exists, there is arranged outside the high pressure seal a collection space for pressure medium which leaks into the space and a device is provided connected with the space to detect changes in the pressure or temperature therein and to produce a signal or to stop the press. The detecting device may be an insulated cable which seals the space on the side remote from the high pressure seal and which may be broken by pressure within the space, thereby interrupting an electrical circuit.
