Abstract

A.L'INVENTION CONCERNE UNE POMPE A LIQUIDE DE REFROIDISSEMENT POUR MOTEURS A COMBUSTION INTERNE REFROIDIS PAR LIQUIDE, COMPRENANT UNE BAGUE E'ETANCHEITE ENTRE L'ESPACE INTERIEUR DE LA POMPE ET LE PALIER VOISIN, ET UN CANAL CONDUISANT A L'AIR LIBRE, DISPOSE A PARTIR DU POINT LE PLUS BAS DE L'ESPACE ANNULAIRE ENTRE LA BAGUE ET LE PALIER. B.CETTE POMPE EST CARACTERISEE EN CE QUE LE CANAL EST ELARGI EN FORME DE CHAMBRE D'EVAPORATION, CETTE CHAMBRE PRESENTANT UN ORIFICE DE TROP PLEIN DEBOUCHANT A L'EXTERIEUR ET PREVU EN SON POINT LE PLUS HAUT. C.L'INVENTION EST APPLICABLE AU REFROIDISSEMENT DES MOTEURS A COMBUSTION INTERNE.A. THE INVENTION CONCERNS A COOLING LIQUID PUMP FOR INTERNAL COMBUSTION ENGINES COOLED BY LIQUID, INCLUDING A SEALED RING BETWEEN THE INSIDE SPACE OF THE PUMP AND THE NEIGHBORING BEARING, AND A CHANNEL CONDUCTING TO FREE AIR, ARRANGE FROM THE LOWEST POINT OF THE ANNULAR SPACE BETWEEN THE RING AND THE BEARING. B. THIS PUMP IS CHARACTERIZED IN THAT THE CHANNEL IS ENLARGED IN THE FORM OF AN EVAPORATION CHAMBER, THIS CHAMBER HAVING AN OVERALL ORIFICE OPENING TO THE EXTERIOR AND PROVIDED AT ITS HIGHEST POINT. C. THE INVENTION IS APPLICABLE TO THE COOLING OF INTERNAL COMBUSTION ENGINES.
