Abstract

L'invention concerne un appareil servant à commander la vitesse du déplacement d'un organe mobile relativement à un support fixe sous l'action d'un entraînement. L'appareil comprend un transducteur de vitesse 22, 23, 24 actionné directement par l'organe mobile 17 et conçu pour fournir un signal électrique proportionnel à la vitesse de mouvement dudit organe mobile à un dispositif de comparaison et de traitement 28 qui reçoit aussi au moins un signal électrique de référence proportionnel à une valeur prédéterminée de la vitesse et fournit un signal de sortie proportionnel à la différence entre le signal du transducteur 22, 23, 24 et le signal électrique de référence, ce signal de sortie étant amené à l'entraînement 1, 11 de maniere à maintenir la vitesse de mouvement de l'organe mobile 17 pratiquement égale à la valeur prédéterminée. Commande du chariot d'une machine à mouler les matières plastiques.
