Abstract

Eine hydraulisch angetriebene Anordnung zum linearen Bewegen eines Massekörpers (10), bestehend aus zwei parallel zueinander geschalteten doppelt wirkenden Arbeitszylindern (11, 12), wobei der eine Arbeitszylinder als Steuerzylinder (11) für die Steuerung der eine Beschleunigungsphase, eine Fahrphase und eine Bremsphase aufweisenden Bewegung des Massekörpors (10) eingerichtet ist und der andere Arbeitszylinder als Antriebszylinder (12) an einen hydraulischen Akkumulator (25) als Energiespeicher angeschlossen ist derart, dass der Akkumulator (25) während der Beschleunigungsphase des Massekörpers (10) die Antriebsenergie für den Antriebszylinder (12) liefert und der Antriebszylinder (12) in der Bremsphase des Massekörpers (10) als Pumpe zum Aufladen des hydraulischen Akkumulators (25) dient, ist dadurch gekennzeichnet, dass Steuerzylinder (11) und Antriebszylinder (12) jeweils einen Kolben (17) mit einseitiger an den Massekörper (10) gekoppelter Kolbenstange (18) aufweisen und dass Steuerzylinder (11) und Antriebszylinder (12) jeweils mittels hydraulisch voneinander getrennter, unabhängiger und jeweils ein Steuerventil (13) bzw. eine drei Steuerkanten (26) bzw. vier Steuerkanten (26) aufweisender Steuerkreise gesteuert sind.
