CA 2257269

A piezoelectric shutter (24) is arranged in a comb pattern (26) and presents a core. The comb is provided with at least one tooth constituting the shutter, the bore being arranged with elevation allowing the displacement of the shutter by the piezoelectric effect. The device is remarkable in that it comprises at least one bimorph (14) arranged on the support, capable of being raised with respect to the support by the piezoelectric effect.

L'invention concerne un obturateur piézoélectrique (24) à configuration en peigne (26) et à structure centrale. Le peigne comporte au moins une dent qui constitue l'élément obturateur, le trou étant situé en élévation pour permettre le déplacement de l'obturateur par effet piézoélectrique. La particularité du dispositif tient en ce qu'il comprend au moins un bimorphe (14), disposé sur le support et susceptible d'être soulevé par rapport à celui-ci par effet piézoélectrique.
