Abstract

Détendeur pour appareil respiratoire de plongée Un piston 52 subit d'un côté la pression ambiante et, de l'autre côté, celle de l'air comprimé d'aval et s'ouvre lorsqu'apparaît entre la première et la seconde un écart en plus déterminé par un ressort 58. Entre l'eau extérieure et le premier côté du piston est interposé un liquide-écran inerte à haut poids moleculaire (graisse de silicone), retenu par des tampons poreux 64 qui laissent passer l'eau Ainsi, le mécanisme est à l'abri des grains de sable, limon, corail et autres présents dans l'eau et qui affectent fâcheusement les joints d'étanchéité et d'autres élements.
