CA 2757404

A check valve includes a retainer tip, operable to be attached to a distal end of a screw shaft, the retainer tip defining at least one melt channel. A first ring is coaxially mounted to and rotationally-coupled with the retainer tip. A second ring is coaxially and slidably mounted to the retainer tip, and is operable to rotate relative to the retainer tip. The second ring is operable to reversibly move between an open position which permits melt to flow through the check valve and a closed position which prevents backflow of the melt.

L'invention porte sur un clapet anti-retour pour une vis. Le clapet anti-retour comprend un embout de retenue, pouvant être fixé sur une extrémité distale d'une tige de vis, l'embout de retenue définissant au moins un canal de coulée. Une première bague est montée de manière coaxiale par rapport à l'embout de retenue et est accouplée en rotation à celui-ci. Une seconde bague est montée de manière coaxiale et coulissante par l'embout de retenue, et peut pivoter par rapport à l'embout de retenue. La seconde bague permet le déplacement réversible entre une position ouverte qui permet à la coulée de traverser le clapet anti-retour et une position fermée qui empêche le reflux de la coulée.
