Abstract

Το μεταβλητό έκκεντρο αποτελείται βασικά από δύο τμήματα το σταθερό τμήμα και το κινητό τμήμα.Οι άξονες συμμετρίας των δύο τμημάτων έχουν την δυνατότητα να αποκλίνουν κατά μίαν επιθυμητή γωνία.Αμφότερα τα τμήματα είναι κατάλληλα διαμορφωμένα ούτως ώστε να συνεργάζονται απολύτως μεταξύ τους και να επιτρέπουν στο έκκεντρο νε λειτουργεί είτε με το σταθερό τμήμα μόνον είτε με τον συνδυασμό και των δύο τμημάτων.Η συνεργασία των τμημάτων, όπως πραγματοποιείται, επιτρέπει την μεταβολή του βυθίσματος της αντιστοίχου βαλβίδας.Η συνεργασία αυτή επιτρέπει επίσης μεταβολή στο άνοιγμα - κλείσιμο της βαλβίδας ή/και στο χρονισμό της εις τρόπον ώστε να βελτιώνει την λειτουργία της μηχανής εσωτερικής καύσεως.Το κινητό μέρος μπορεί να κινείται είτε με μηχανικό, είτε με υδραυλικό μέσον είτε με άλλον τρόπο, ενώ χρησιμοποιούνται διάφορα συστήματα επαναφοράς και ασφάλισης.Η παρούσα εφεύρεση μπορεί να εφαρμοσθεί σε όλους τους τύπους εμβολοφόρων μηχανών εσωτερικής καύσεως χωρίς καμμιά μετατροπή της μηχανής.ωThe variable cam basically consists of two parts, the fixed part and the movable part. The axes of symmetry of the two parts have the ability to deviate by a desired angle. Both parts are suitably shaped so that they cooperate perfectly with each other and allow the cam it works either with the fixed part only or with the combination of both parts. The cooperation of the parts, as it is carried out, allows the change of the draft of the corresponding valve. This cooperation also allows a change in the opening - closing of the valve and/or the timing it in such a way as to improve the operation of the internal combustion engine. The movable part can be moved either mechanically, hydraulically or otherwise, while various return and locking systems are used. The present invention can be applied to all types of internal combustion piston engines without any conversion of the engine.o
