Abstract
Soupape assurant la commande, en fonction de la température, d'appareils auxiliaires d'un système de préparation du mélange d'air et de carburant pour moteurs à combustion interne. La soupape comporte une enceinte 12 délimitée par une membrane 3 soumise à la dépression qui règne dans le tuyau d'aspiration. Cette membrane est fixée sur une tige 7 dont une extrémité porte un clapet 5 tandis que son autre extrémité porte un piston 9 placé dans une chambre à huile 8. Application à la commande temporisée d'appareils pour moteurs à combustion interne
