Prinziti der bekannten hydraulischen η zwei Ausführungen.Principle of the well-known hydraulic η two versions.

In der auf der rechnen Seite gezeichneten Ausführung ist 1 der eigentliche zylindrische Körper aus Metall mit Innengewinde. 2 ist eine darin vorgesehene ringförmige Kammer, welche mit einem hydraulischen Medi ujt ('Fett, OeI, Staub) gefüllt ist. 3 ist eine Ringdichtung, U ein Druckring aus Stahl, 5 ein Schmiernippel mit Rückschlagventil über welchen mittels einer DruckuresseMedium in die Kammer eingepresst und der Druck in ihr erhöht werden kann, 6 eine verschliessbare Entlüftungsöffnung, über welche die Kammer entlastet werden kann.Statt mittels Druckpresse und Schmiernippel kann die Mutter auch durc.i Anschluss an eine hydraulische Druckleitung betätigt werden. Die Druckerhöhung in der Kami er überträgt sich über die ringdichtung 3 auf den Druckring U, sodess zwischen iiiner Auflagefläche 11/ dajileinzusnannenden Teil# 11a un der Grundplatte 12a einerseits una ardererseits den mit dei Grundplatte 12a festverbunden Bewindebolzen 12feir?e Verst>annung hervorgerufen wiru, welche b*ri ILe-d-arTf durch Oeffnun«· der Entlüftungsschrr übe 6 wieder beseitigt werden kann.In the count on the side is drawn embodiment 1 of the actual cylindrical body M etal with internal thread. 2 is an annular chamber provided therein, which is filled with a hydraulic medium (fat, oil, dust). 3 is a ring seal, U is a pressure ring made of steel, 5 is a grease nipple with a non-return valve through which a pressure medium can be pressed into the chamber and the pressure can be increased, 6 a closable vent opening through which the chamber can be relieved, instead of using a pressure press and grease nipple, the nut can also be operated by connecting it to a hydraulic pressure line. The increase in pressure in the chamber is transmitted via the ring seal 3 to the pressure ring U, so that between a support surface 11 / dajileinzusnannenden part # 11a and the base plate 12a on the one hand and on the other hand the screw bolt 12, which is firmly connected to the base plate 12a, is created. which b * ri Ile-d-ARTF by Oeffnun "· the practice Entlüftungsschrr 6 again can be eliminated.

In der auf der rächt en Seite gezeigten Ausführung ist kein Schmiernipnel(und keine fettpresse) vorgesehen. Zwecks Druck-. erzeugung sind in einer Bohrung des Körpers 1 ein Druckkolben mit einer Dichtung 8 angeordnet, welche mittels einer Schraube beaufschlagt werden, '-reiche oben mit einem Innensechskant versehen ist, und durch deren hineinschrauben der Druck im Baum 2 erhöht werden kann. Die übrigen Einrichtun-en und Wirkungen sind die gleichen wie im ersten Beispiel.In the version shown on the avenging side there is no Grease nipple (and no grease gun) provided. Purpose of printing. generation are arranged in a bore of the body 1, a pressure piston with a seal 8, which by means of a screw are acted upon, '-reich is provided with a hexagon socket at the top, and by screwing it in, the pressure in the Tree 2 can be increased. The other facilities and Effects are the same as in the first example.
