Abstract

Dispositif permettant l'allumage du mélange explosif par l'intermédiaire de la bougie piézo-électrique pour les moteurs du type à explosion deux temps et quatre temps. La caractéristique technique principale de l'invention est le fait que pour produire l'étincelle entre les deux électrodes de bougie, on n'utilise pas d'énergie, électrique mais un effet piézo-électrique, dont la propriété est possédée par certains diélectriques, qui consiste à une apparition de charge électrique sous l'influence de tension ou de déformation mécanique. Ce phénomène est obtenu par compression de deux matériaux piézo-électrique de polarité inverse de chagge électrique. Nous obtenons ainsi un mélange sous forme d'une éfluve d'une tension variable de 20 kv à 30 kv. L'objet de l'invention est l'utilisation des matériaux piézoélectriques qui peuvent être des cristaux naturels, des cristaux artificiels ou polis cristallins, ce sont des corps anisotropes, selon la loi de Curie. L'invention peut être utilisée pour l'allumage de tous types de moteurs à explosion.
