Abstract

a. Détecteur de vibrations. b. Détecteur caractérisé en ce que l'élément piézo-électrique est conçu sous forme d'oscillateur sous vibrations de flexion, serré à une extrémité à l'aide d'un dispositif de contrainte et rigidement relié par l'intermédiaire de ce dispositif de contrainte avec la pièce du moteur à combustion interne qui transmet le bruit du cognement et dirigé transversalement à la direction des vibrations de cette pièce du moteur à combustion interne c. L'invention s'applique notamment aux moteurs d'automobiles.
