ACTIONNEUR DE REGISTRE PNEUMATIQUE MP909D ACCOUPLEMENT DE TYPE ÉPAULEMENT FONCTIONNEMENT TYPE Fixer l'accouplement à un axe à épaulement, comme l'illustrent les Fig. 4 et 5. Lorsqu'il sert à faire fonctionner un registre d'air extérieur d'un ventilo-convecteur, le MP909D est commandé par un relais électropneumatique. Lorsque le ventilateur se met en marche, le registre normalement fermé s'ouvre; lorsque le ventilateur cesse de fonctionner, le registre se referme. Voir la Fig. 6.
