Abstract

CE DISPOSITIF EST DU TYPE DE CEUX DANS LESQUELS IL EST PREVU DANS LA ZONE DU PISTON AU MOINS UN PASSAGE 44, QUI FAIT COMMUNIQUER ENTRE EUX LES DEUX COMPARTIMENTS 45, 46 DE LA CAVITE INTERIEURE 33 DU CYLINDRE 7, PASSAGE QUE DES MOYENS DE COMMANDE OUVRENT OU FERMENT SUIVANT LE SENS DU DEPLACEMENT AXIAL DU PISTON. DANS LE DISPOSITIF SELON L'INVENTION, CES MOYENS SONT CONSTITUES PAR UNE JUPE 3, QUI PROLONGE LE PISTON 1 EN DIRECTION D'UNE DES EXTREMITES DU CYLINDRE ET DONT L'EXTREMITE LIBRE, MUNIE SUR SA FACE EXTERNE D'UNE SAILLIE ANNULAIRE 4, EST APPLIQUEE CONTRE LA FACE INTERNE 30 DU CYLINDRE LORSQUE LA PRESSION DANS UN 45 DES COMPARTIMENTS AUGMENTE, OBTURANT AINSI LE PASSAGE ENTRE LE PISTON ET LADITE FACE INTERNE.
