Abstract

L'invention concerne une vanne à ouverture rapide pour fluide sous pression élevée. La vanne comporte un corps à alésage central présentant une extrémité d'admission fermée dont les parois sont munies d'orifices de passage de fluide et une extrémité d'échappement. Un tiroir est mobile dans l'alésage entre une position d'obturation des orifices et une position d'ouverture où le fluide sous pression qui baigne l'extérieur de l'extrémité d'admission du corps peut s'écouler dans l'alésage. Application à l'étude sismique des fonds sous-marins en coopération avec un réservoir de vapeur sous pression.
