Description

Hydraulische Presse.Hydraulic press.

Die Beseitigung von mit dem Kolben einer hydraulisches, Presse aus deren Zylinder austretendem Drucköl bzw. dessen Rückführung in den Zylinder bietet Schwierigkeiten.- Nach der Erfindung wird das Lecköl, welches vom Kolben 1 durch einen Abstreifring 2 abgestreift wird, in einem am oberen Ende des Zylinders der hydraulischen Presse angeordneten vorzugsweise ringförmigen Raum 3 gesammelt.The elimination of pressure oil escaping from its cylinder with the piston of a hydraulic press or its return into the cylinder presents difficulties. According to the invention, the leakage oil, which from the piston 1 through a scraper ring 2 is stripped off, in one at the upper end of the cylinder of the hydraulic press arranged preferably annular space 3 collected.

Dieser Raum ist mit dem Zylinderraum 4 durch einen Kanal 5 verbunden, welcher durch ein vorbelasteten Ventil 6 gesperrt ist.This space is connected to the cylinder space 4 by a channel 5, which is blocked by a preloaded valve 6.

Der ringförmige Raum 3 nimmt einen zusammendrückbaren Körper, beispielsweise einen mit Luft gefüllten Hohlkörper 7 mit elastischen Wänden auf.The annular space 3 takes a compressible body, for example an air-filled hollow body 7 with elastic walls.

Sammelt sich nun Lecköl in dem ringförmigen Hohlraum 3, so füllt sich dieser allmählich so weit, dass der Hohlkörper 7 zusammengepresst wird und im Raum 3 ein'Druck entsteht*-Im Ruhezustand der Presse wird das Ventil 6 nur durch die Vorbelastung, beispielsweise durch die Feder 8 geschlossen. Sobald der Druck im Hohlraum 7 grösser ist als die Vorbelastung des Ventiles 6, vermehrt durch den Druck im Zylinder 4, öffnet sich das Ven- til 6 und lässt das angesammelte Lecköl so weit in den Presszylin- derzurückfliessen, bis Druckleichheit zwischen diesem und dem Hohlraum 3. hergestellt ist. If leakage oil now collects in the annular cavity 3, it gradually fills so far that the hollow body 7 is compressed and a pressure is created in space 3 Spring 8 closed. Once the The pressure in the cavity 7 is greater than the preload on the valve 6, increased by the pressure in cylinder 4, the valve opens til 6 and lets the accumulated leakage oil so far into the press cylinder flow back until the pressure is equal between this and the Cavity 3. is made.
