Abstract

Procédé et appareil de rinçage d'un espace interstitiel très étroit constitué entre un premier organe pourvu d'un alésage et un second organe inséré et fixé dans ledit alésage et dont une extrémité est bloquée. On fait communiquer cet espace interstitiel avec un espace rempli d'un liquide de rinçage, on applique une pression au liquide de rinçage et on chauffe localement l'extrémité bloquée de l'espace interstitiel. De préférence, alors qu'on chauffe localement l'extrémité bloquée dudit espace interstitiel, on réduit la pression du liquide pressurisé et, si nécessaire, on répète la pressurisation et la réduction de pression pour obtenir un meilleur rinçage. Application : rinçage appareils et d'instruments pour élimination de matières nocives.
