Abstract

In electro-pneumatic or electro-hydraulic control apparatus a certain predetermined pressure must be adhered to. Pressure changes are used to activate a control or switching mechanism functioning at the same pressure as the system. Preferably, a wire-compensator with safety catch is used.
