Abstract

L'invention concerne un appareil de commande pneumatique de moteur à combustion interne Il comporte essentiellement une soupape de commande à dépression dont la chambre reçoit, de chaque côté d'un diaphragme, des dépressions différentes prélevées en des points différents de la tubulure d'admission, ou l'une de ces dépressions est la pression atmosphérique. Les dépressions sont transmises par l'intermédiaire de limiteurs d'écoulement qui en retardent la transmission. La soupape de commande à dépression peut agir sur le dispositif d'avance à l'allumage, ou sur tout autre dispositif de commande du moteur. L'invention s'applique particulièrement à des moteurs à combustion interne comportant un dispositif d'épuration des gaz d'échappement.
