Claims (6)

1. Hydraulischer Zylinder mit einem in einem Zylinderrohr zwischen zwei Endanschlägen längsverschiebbaren Kolbenstange mit Kolben und einer an beiden Enden wirksamen Endlagendämpfung, dadurch gekennzeichnet, dass die Endlagendämpfungseinrichtung mit geringem baulichen Aufwand durch mehrere hintereinanderliegende kleine Drosselbohrungen (11) in der Wand des Zylinderrohres (1) vor den jeweiligen Endanschlägen des Zylinders angeordnet ist.1. Hydraulic cylinder with a piston rod with piston that is longitudinally displaceable in a cylinder tube between two end stops and an end position damping effective at both ends, characterized in that the end position damping device is constructed with several small throttle bores ( 11 ) one behind the other in the wall of the cylinder tube ( 1 ) with little construction effort. is arranged in front of the respective end stops of the cylinder. 2. Hydraulische Zylinder nach Anspruch 1, dadurch gekennzeichnet, das der Kolben (3) des Zylinders diese Drosselbohrungen (11) beim Überfahren verschließt und den Ausström­ querschnitt entsprechend der Bohrungsgröße verringert.2. Hydraulic cylinder according to claim 1, characterized in that the piston ( 3 ) of the cylinder closes these throttle bores ( 11 ) when driving over it and the outflow cross section is reduced in accordance with the bore size. 3. Hydraulischer Zylinder nach Anspruch 1 und 2, dadurch gekennzeichnet, dass der jeweilige Druckflüssigkeitszuleitungsanschluss für die Kolbenfläche (7) oder die Ringfläche (6) beim Dämpfungsvorgang durch den hydraulisch entstehenden Druck durch ein Rückschlagventil, gebildet aus einer Kugel (9) und einer Druckfeder (10) automatisch verschlossen wird und als Ausströmquerschnitt nur der Gesamtquerschnitt der Drossel­ bohrungen (11) wirksam ist.3. Hydraulic cylinder according to claim 1 and 2, characterized in that the respective hydraulic fluid supply connection for the piston surface ( 7 ) or the annular surface ( 6 ) during the damping process by the hydraulically generated pressure by a check valve, formed from a ball ( 9 ) and a compression spring ( 10 ) is automatically closed and only the total cross section of the throttle bores ( 11 ) is effective as the outflow cross section. 4. Hydraulischer Zylinder nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass der jeweilige Druckflüssigkeitszuleitungsanschluss für die Kolbenfläche (7) oder die Ringfläche (6) beim Anfahrvorgang das Rückschlagventil durch den hydraulisch Druck geöffnet wird und der entstehende Einströmquerschnitt die Drosselwirkung der Drossel­ bohrungen (11) beim Arbeitsvorgang aufhebt.4. Hydraulic cylinder according to claim 1 to 3, characterized in that the respective hydraulic fluid supply connection for the piston surface ( 7 ) or the annular surface ( 6 ) during the start-up process, the check valve is opened by the hydraulic pressure and the resulting inflow cross-section, the throttle effect of the throttle bores ( 11 ) during the work process. 5. Hydraulischer Zylinder nach Anspruch 1 bis 4, dadurch gekennzeichnet, dass ein Einstellelement (12) mit mechanischen Abdichtelementen (13) und mit Bohrungen (14) die in Form und Lage mit den Drosselbohrungen (11) identisch sind, angebracht ist.5. Hydraulic cylinder according to claim 1 to 4, characterized in that an adjusting element ( 12 ) with mechanical sealing elements ( 13 ) and with bores ( 14 ) which are identical in shape and position with the throttle bores ( 11 ) is attached. 6. Hydraulischer Zylinder nach Anspruch 5, dadurch gekennzeichnet, dass das Einstellelement (12) drehbar oder verschiebbar angeordnet ist und dadurch die Größe des Gesamtwirkungsquerschnitt aus den Drosselbohrungen (11) des Zylinderrohres und den Bohrungen (14) des Einstellelementes durch Einstellung verringert werden kann.6. Hydraulic cylinder according to claim 5, characterized in that the adjusting element ( 12 ) is rotatably or displaceably arranged and thereby the size of the total cross-section of the throttle bores ( 11 ) of the cylinder tube and the bores ( 14 ) of the adjusting element can be reduced by adjustment.
