Abstract

La présente invention a pour objet un dispositif pour commander l'expansion d'un rodoir dont l'expansion est obtenue par un cône solidaire en translation d'une tige d'expansion solidaire elle-même d'un piston de vérin hydraulique. Selon l'invention le vérin hydraulique 1-2-3-12 est à effet différentiel et le piston 12 est asservi en position par une valve hydraulique 22-23 à pilotage rotatif déterminé par un moteur pas-à-pas 34 en liaison avec une commande numérique programmée.
