Abstract

PISTON POUR MOTEUR A COMBUSTION INTERNE, NOTAMMENT POUR MOTEURS DE TYPE DIESEL. AFIN DE RESTREINDRE LA DIFFUSION CALORIFIQUE S'ETENDANT DE LA FACE DE COMPRESSION 5 VERS LA ZONE 6 D'IMPLANTATION DES SEGMENTS D'ETANCHEITE, UNE GORGE CIRCULAIRE INTERNE 8 REDUIT L'EPAISSEUR 9 DE RACCORDEMENT DU FOND 4 DE LA TETE DE PISTON A LADITE ZONE 6 D'IMPLANTATION DES SEGMENTS D'ETANCHEITE, ET CETTE GORGE 8 EST INTERROMPUE ET IL LUI EST SUBSTITUE, SENSIBLEMENT AU NIVEAU DE CE RACCORDEMENT, UNE ENTAILLE 12 TANGENTIELLE EXTERNE SUR LA FACE LATERALE 6 DU PISTON, DANS LES REGIONS OU DES CONCAVITES 10 DE LA FACE DE COMPRESSION 5 RENDRAIENT CETTE EPAISSEUR DE RACCORDEMENT TROP FAIBLE. APPLICATION AUX PISTONS POUR MOTEURS FONCTIONNANT A TEMPERATURES ET PRESSIONS ELEVEES, TELS QUE DES MOTEURS DU TYPE DIESEL.
