Abstract
Η εφεύρεση αφορά τον υδραυλικό έλεγχο σε ένα υδραυλικό σύστημα για την λειτουργία μίας εργαλειομηχανής όπως μίας πρέσας για την επεξεργασία υλικών ενός συγκεκριμένου τύπου, ειδικά για τη λειτουργία μηχανής ψαλλιδίσματος από μετάλλων. Αυτός ο έλεγχος επιτρέπει απόσβεση κτύπου και συνδυασμένη γρήγορη μετατόπιση με αντιστάθμισμα βάρους και μεταφορά ενός υδραυλικού μέσου ενός υδραλικού κυλίνδρου για την κίνηση των άλλων. Σύμφωνα με την εφεύρεση, αυτός ο έλεγχος αποτελείται από υδραυλικά μέσα ενός υδραυλικού κύλινδρου για τον προ-έλεγχο μίας πρώτης κυρίως βαλβίδας (2.4.0), μιας δεύτερης κυρίως βαλβίδας (2.7.0) και μίας τρίτης κυρίως βαλβίδας (3.7.0) οι οποίες λειτουργούν συνδυασμένες και μία τέταρτη βαλβίδα (2.5).
