A control device (26) for controlling a pressure delivered ía a fluid-operated actuator (18) far actuating an electric current collector assembly (10) transmitting energy between an electrical line (20) and a vehicle (12) is provided with a fluidic circuit (24) comprising a pleasure input (28) far connecting the fluidic circuit (24) to a pressure supply (22), a pressure output (29) for connecting the fluidic circuit (24) to die fluid-operated actuator (18), an electrically operated pressure regulator (44) far delivering a first regulated output pressure in response to an electrical set value, an second pressure regulator (46) for delivering a s,wond regulated. output pressure in response to a non-electrical set value, and seleotion means far detecting a specific condition and far selectively directing the air from the input to the output through the second pressure regulator when flee specific condition is detected., The selection means comprise a directional control valve means (42) connected between the electrically operated pressure regulator (44), the second pressure regulator (46)and the pressure output (29). |
