Abstract

Ce cylindre de travail avec freinage, dans la chambre duquel peut être injecté un fluide moteur, et qui présente au moins un passage qui traverse sa paroi pour échappement du fluide moteur. Ce passage 16 s'ouvre dans la chambre du cylindre 4 le long d'une section de la course du piston 2 vers la paroi frontale 3, section au niveau de laquelle doit s'effectuer le freinage. Lors de son mouvement vers la paroi frontale, le piston recouvre cet orifice d'où il résulte que l'échappement du fluide moteur est étranglée peu à peu, si bien que la vitesse du piston est réduite avant que le piston n'atteigne la paroi frontale. Ce cylindre de travail peut être un servo-moteur hydraulique dont la tige de piston est reliée à un moule de soufflage.This working cylinder with braking, into the chamber of which a working fluid can be injected, and which has at least one passage which passes through its wall for the escape of the working fluid. This passage 16 opens into the chamber of the cylinder 4 along a section of the stroke of the piston 2 towards the front wall 3, the section at which the braking must take place. During its movement towards the front wall, the piston covers this orifice from which it results that the exhaust of the working fluid is throttled little by little, so that the speed of the piston is reduced before the piston reaches the wall. frontal. This working cylinder can be a hydraulic servo motor, the piston rod of which is connected to a blow mold.
