Safety apparatus for automatic supervision and control of a pressure fluid system

摘要

In a safety apparatus for automatic leakage supervision at a pressure fluid transition in a contact zone between two interconnected, pressures fluid conducting members there is formed in at least one of the members a passage which opens into the contact zone. The passage contains a pressure medium. Means are provided to maintain a certain predetermined normal pressure in the passage and a monitoring means is adapted to monitor the pressure in the passage to indicate deviations from the normal pressure.
