Claims (8)

1. Hydraulischer Stempel, insbesondere für den Bergbau dadurch gekennzeichnet, daß ein mit mechanischen Mittel abgedichtetes Zylinderrohr (3) mit einem Kolbenrohr mit Kolben (6) fest verbunden ist und zwischen den beiden, ein mit mechanischen Mitteln ab­ gedichtetes Kolbenrohr mit Kolben (1) axial verschieblich angeordnet ist.1. Hydraulic plunger, in particular for mining, characterized in that a cylinder tube ( 3 ) sealed with mechanical means is firmly connected to a piston tube with piston ( 6 ) and between the two, a piston tube with piston ( 1 ) sealed with mechanical means. is axially displaceable. 2. Hydraulischer Stempel nach Anspruch 1, dadurch gekennzeichnet, daß das Kolbenrohr mit Kolben (6) einen Druckflüssigkeitszuleitungskanal für die Kolben­ fläche (4) bildet.2. Hydraulic stamp according to claim 1, characterized in that the piston tube with the piston ( 6 ) forms a hydraulic fluid supply channel for the piston surface ( 4 ). 3. Hydraulischer Stempel nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Kolbenfläche (4) des Zylinders mit Kolben (6) zusammen mit Ringkolbenfläche (9), gebildet aus dem Zylinder (3) und dem Zylinder mit Kolben (6) über den Anschluß (11) und (10) zusammen eine große Kolbenfläche bilden, die auf den Zylinder (1) wirkt.3. Hydraulic stamp according to claim 1 and 2, characterized in that the piston surface ( 4 ) of the cylinder with piston ( 6 ) together with the annular piston surface ( 9 ), formed from the cylinder ( 3 ) and the cylinder with piston ( 6 ) over the Port ( 11 ) and ( 10 ) together form a large piston area, which acts on the cylinder ( 1 ). 4. Hydraulischer Stempel nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß der Zuleitungskanal des Zylinders (6) zur Aufnahme einer Rückzugsfeders dient und der Stempel daher auch ohne Drucknutzung über die Einfahr-Ringflächen einfahren kann.4. Hydraulic stamp according to claim 1 to 3, characterized in that the supply channel of the cylinder ( 6 ) serves to receive a return spring and the stamp can therefore retract without using pressure on the retractable ring surfaces. 5. Hydraulischer Stempel nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß über den Anschluß (12) und (13) die sich bildenden Ringflächen verbunden sind.5. Hydraulic stamp according to claim 1 to 3, characterized in that the ring surfaces which are formed are connected via the connection ( 12 ) and ( 13 ). 6. Hydraulischer Stempel nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß die Oberflächen des Stempel mit Duroplastkunststoff beschichtet sind und der Stempel daher mit klarem Wasser betrieben werden kann.6. Hydraulic stamp according to claim 1 to 3, characterized in that the surfaces of the stamp are coated with thermoset plastic and the Stamp can therefore be operated with clear water. 7. Hydraulischer Stempel nach einem der Anspruche 1 bis 6, dadurch gekennzeichnet, daß die Abdichtungen und Führungen (5, 7, 8, 14) Gleitmittelkomponenten enthalten und der Stempel daher mit klarem Wasser betrieben werden kann.7. Hydraulic stamp according to one of claims 1 to 6, characterized in that the seals and guides ( 5 , 7 , 8 , 14 ) contain lubricant components and the stamp can therefore be operated with clear water. 8. Hydraulischer Stempel nach einem der Anspruche 1 bis 7, dadurch gekennzeichnet, daß der Stempel als Einzelstempel für den Bergbau eingesetzt wird.8. Hydraulic stamp according to one of claims 1 to 7, characterized in that the stamp is used as a single stamp for mining.
