Abstract
A centering device for a mechanical tracer, with a flexural bar and at least two centering systems. Each centering system includes a pair of pistons which act on the flexural bar in opposite directions. A stop for one piston of each pair is provided, such that the piston bearing against the stop exerts, at least near the state of rest, twice as high a return force as the second piston of the pair. At least two centering systems are provided in order to impart different force/path characteristics to the tracer.
