Abstract

Source de sons sismiques permettant de libérer un gaz sous pression dans une masse d'eau. Dans une forme de réalisation, il comprend une chambre 82 pour le gaz, avec une lumière d'échappement 56 par laquelle le gaz peut être libéré, un obturateur de soupape 96 qui peut aller et venir dans la chambre et qui peut prendre différentes positions d'obturation contre la lumière d'échappement pour empêcher le gaz de sortir de la chambre, un orifice 104 traversant l'obturateur, et un mécanisme d'actionnement 60 pour faire passer rapidement l'obturateur de soupape, suivant un mouvement continu, d'une première position d'obturation à une seconde position d'obturation différente, en passant par une position d'ouverture dans laquelle l'orifice 104 se trouve dans le prolongement de la lumière d'échappement 56 de façon à libérer une partie du gaz. Exploration sismique.
