Abstract

L'INVENTION CONCERNE LES SOURCES SISMIQUES DANS LESQUELLES ON CREE UNE ONDE DE CHOC DANS UNE MASSE LIQUIDE PAR IMPLOSION D'UN VOLUME DE VAPEUR, EN PARTICULIER DE VAPEUR D'EAU. SELON L'INVENTION, LE VOLUME A IMPLOSER EST FORME A L'INTERIEUR D'UNE ENCEINTE FERMEE DEFORMABLE 14, ENTOURANT UNE TETE D'INJECTION 12, MUNIE D'UN ORIFICE DE VAPEUR 103 SUSCEPTIBLE DE RECEVOIR DE LA VAPEUR A 5 BARS ET 170C SOUS LA COMMANDE D'UNE ELECTROVANNE 102. AVANTAGEUSEMENT, ON AMENE DES GERMES LIQUIDES DANS CETTE VAPEUR A L'AIDE D'UNE CONDUITE D'EAU FROIDE SOUS PRESSION 111, ET SOUS LE CONTROLE D'UNE ELECTROVANNE 113, CETTE EAU ARRIVANT DANS LA CAVITE 114 POUR SORTIR PAR LES ORIFICES DE PULVERISATION 115. CES GERMES CREENT UNE CHUTE BRUTALE DE PRESSION A L'INTERIEUR DE LA VAPEUR, D'OU UNE IMPLOSION ET UNE ONDE DE CHOC, APRES LAQUELLE UNE CONDUITE 131 PERMET DE RECUPERER LE CONDENSAT. APPLICATION NOTAMMENT COMME SOURCE SISMIQUE MARINE.
