There is provided a body 10 connected to a fixed point 9' and having two projecting portions 11, 12, for a particular segment, relative to the connection, said portions 11, 12 being able to experience displacements in a plane; furthermore, there are two pushing means 21, 22, each able to be connected to a corresponding pressure zone and able to produce a thrust F1, F2 proportional to the pressure P1, P2 received, said thrust F1, F2 being applied to a corresponding projecting portion 11, 12 at a predetermined distance from the connection and being able to produce a moment of force with respect to the connection, able to displace the particular projecting portion 11, 12 in said plane of displacement; there are also provided means able to vary the moment of the thrust F2 produced by a pushing means 22 and acting on the corresponding projecting portion 12 relative to the other moment; finally, there are provided means able to put out a final signal S having a value proportional to the difference between the values of the two moments produced by the pushing means 21, 22 on the two projecting portions 11, 12. <IMAGE> |
