Abstract

Détecteur de variation insensible aux chocs, à commande retardée. La masse d'inertie constitue un piston se déplaçant de façon étanche dans le cylindre Un ressort maintient le piston qui détermine deux chambres communiquant entre elles par un canal portant une soupape. Chacune des chambres communique avec l'atmosphère. Un pointeau de réglage fait communiquer la chambre inférieure avec l'atmosphère. Le piston porte à sa partie inférieure des moyens de commutation électrique Application à la commande de dispositifs pour mobiles soumis à une décélération.
