Electromechanical remote-control device

An electromechanical remote-control device comprising:

• a first flexible control cable arranged in an external sheath and connected to an actuator of a control assembly;
• a second driven flexible cable arranged in an external sheath and connected to an application that is to be controlled;
• and
• a servomechanism powered by a power source for transmitting movements of said first control cable to said second driven cable and thus from the actuator to the application, wherein said servomechanism includes,
• two coaxial neutral levers with two corresponding bodies, respectively, each body having a cylindrical sector which covers an arc of a circle that is slightly less than 180.degree. including 180.degree.-2.alpha., where a first one of said levers is attached to said first control cable and a second one of said levers is attached to said second driven cable,
• a drive shaft arranged coaxially inside the bodies of said levers,
• a spiral spring arranged between the bodies of said levers and said drive shaft, said spiral spring having outward-facing opposing ends that extend between edges of said bodies, wherein said spring is tightly wound on said drive shaft,
• a cursor attached to a sheath of said first control cable for effecting movements (X, Y) that are smaller in size and opposite in direction to the movement of said control cable in push or in pull,
• a transducer connected to said cursor for detecting said movements (X, Y) of said cursor, and
• an electronic control unit connected to said drive shaft in the two directions of rotation depending on movements (X, Y) of said cursor such that said remote control can be effected electromechanically or, in the event that the electromechanical components malfunction, mechanically, thus guaranteeing that control can be effected at all times.
