Abstract
Commande de presse hydraulique. Le vérin est caractérisé en ce que le cylindre 5 présente un premier alésage 8 de section supérieure à celle du piston 6, s'étendant sur la majeure partie de sa longueur et raccordé à un second alésage 10 de section correspondant au piston et délimité à proximité du fond 4 prolongé par la tige creuse 14 qui présente une section supérieure à celle d'une partie 7b de la tige de piston 7 prolongeant la partie 7a délimitant l'alésage de reception de la tige 14. Application aux presses à injecter les matières plastiques.
