Abstract

L'invention concerne un réfrigérateur miniature du type à détente isenthalpique. Un conduit d'alimentation 13 se terminant par un orifice calibré 20 est raccordé en 33 à un réservoir de stockage sous haute pression 30, par une vanne à pointeau 35 et diaphragme 36 d'une part via l'orifice 50, d'autre part via l'orifice 43 à clapet 41 soumis à un ressort 42 et à un soufflet 45. A la rupture du diaphragme 36, la haute pression est transmise avec retard grâce à l'orifice calibré 47 au soufflet 45 qui, progressivement, amène le clapet 41 à fermer l'orifice 43. Application à la mise en froid rapide de sondes et détecteurs
