Abstract

L'INVENTION EST RELATIVE A UN MOTEUR A COMBUSTION INTERNE DONT LE BLOC MOTEUR A PISTONS ALTERNATIFS EST ENFERME DANS UNE CUVETTE ETANCHE. SELON L'INVENTION, LE BLOC MOTEUR PRESENTE SUR SES DEUX COTES FRONTAUX DES BLOCS INSONORISANTS COAXIAUX AU VILEBREQUIN, SERVANT D'ELEMENTS DE SOUTIEN, PAR LESQUELS IL EST MAINTENU CENTRE DANS LA CUVE EXTERIEURE ET IMMOBILISE AXIALEMENT, TANDIS QU'ENTRE LE BLOC MOTEUR ET LE BORD SUPERIEUR DE LA CUVE EXTERIEURE EST SIMPLEMENT PREVU UN JOINT D'HUILE. LE MOTEUR, D'UN SILENCE APPRECIABLE, EST UTILISABLE POUR LES ENGINS A CABINE DE CONDUITE FIXEE SUR L'ENVELOPPE EXTERNE DU MOTEUR.
