Abstract

L'addition a pour objet des perfectionnements et modifications apportés au brevet principal visant à assurer d'une part un bon balayage des cylindres surtout aux faibles charges et/ou aux faibles vitesses, et d'autre part une diminution du taux de compression effectif entraînant un abaissement des températures de préférence aux charges et/ou aux vitesses élevées du moteur. Selon l'addition, est prévu dans le conduit d'admission un système 109 constitué par un clapet anti-retour 111 et une soupape 110 dont le degré d'ouverture est fonction notamment de la vitesse et/ou de la charge du moteur. Ce clapet 111 est solidaire de la soupape 110 et constitué par des orifices axiaux 113 prévus dans la tête 114 de la soupape et par une membrane 115 solidaire de la tête de soupape et susceptible d'obturer lesdits orifices 113. L'addition s'applique notamment aux gros moteurs Diesel.
