Abstract

Machine à piston d'injection comportant un poinçon à l'extrémité d'une tige. Le poinçon 2 est mobile axialement par rapport à sa tige 1, c'est-à-dire est translatable sur cette dernière contre la force d'un dispositif hydraulique d'amortissement lorsqu'une pression s'exerce sur sa face extreme 36. Application aux machines de coulée de métaux sous pression afin d'éviter les pointes de pression à la transition entre la pression de remplissage et la pression finale.
