The present invention reveals an improvement in an apparatus for injection molding a metallic material having dendritic properties. In the improvement, a sub--ring is placed under a piston ring on a sliding seal ring of a non-return valve assembly. The sub-ring seals the pressure and metal flow in the apparatus, virtually eliminates piston ring leakage and extends the usable life of the non-return valve assembly.
La présente invention concerne une amélioration relative à un appareil de moulage par injection de matériau métallique présentant des propriétés dendritiques. Dans ladite amélioration, un sous-segment (47) est placé sous un segment de piston (46) sur un segment d'étanchéité coulissant (44) d'un ensemble soupape de non-retour (18). Le sous-segment assure l'étanchéité à la pression et au flux de métal dans l'appareil, il élimine virtuellement les fuites du segment de piston et prolonge la vie utile de l'ensemble soupape de non retour.
