Abstract
Presse de moulage par injection dans laquelle un piston (24) est introduit dans un barillet (22) et pourvue d'une entrée de matière du côté arrière du barillet, une valve étant prévue dans la périphérie intérieure du barillet et un corps de valve (24a) qui peut être amené au contact du siège de valve (22a) étant prévu à l'extrémité du piston (24), une unité de déplacement longitudinal étant en outre dans l'alignement du piston (24) et, lorsque le piston est déplacé longitudinalement, une pièce présentant des diamètres croissants est amenée au contact d'une pièce présentant des diamètres décroissants de telle sorte qu'un passage de matière soit ouvert et fermé.
