Description

  

      Druckflüssigkeitspresse    mit mehreren gleichachsig ineinander angeordneten Zylindern.    Gegenstand vorliegender Erfindung ist  eine     Druckflüssigkeitspresse,    zum Beispiel  eine     Druckwasserpresse,    mit mehreren gleich  achsig ineinander angeordneten Zylindern.  Sie ist dadurch gekennzeichnet, dass als An  schlag für jeden Zylinder in seiner aus  geschobenen Stellung ein in seine äussere       Wandung    eingelassener Spannring dient, der  beim     Auseinanderschieben    in eine Nut des  ihn umfassenden Zylinders     eindringt    und  beim     Ineinanderschieben    der Zylinder wieder  in seine Anfangslage zurückgedrückt wird.  



  <B>Auf</B> der Zeichnung ist der Erfindungs  gegenstand in einem Ausführungsbeispiel  dargestellt. Es zeigt:     Fig.    1 die Presse im  Längsschnitt mit     ineinandergeschobenen    Zy  lindern,     Fig.    2 die Presse mit     ausgeschobe-          nen    Zylindern, teilweise im Längsschnitt;       Fig.    $ bis 5 zeigen Einzelheiten.  



  Es bedeuten a die Zylinder der Presse.       b    ist die äussere Wandung jedes Zylinders,  der von einem weiteren Zylinder umgeben ist.  c sind Spannringe, die in die äussere Wan-         dung    dieser Zylinder eingelassen sind. d sind  Nuten in der innern Wandung der Zylinder,  in die bei     ausgeschobener.    Stellung der Zy  linder die Spannringe c eindringen, um den       Ausschub    der Zylinder gegeneinander zu be  grenzen. e sind die Zylinderdichtungen, die  sich unterhalb der Spannringe c befinden.  f sind die Kanäle, die die Druckflüssigkeit  unter die Dichtungsringe gelangen lassen.  g ist. der Eintrittskanal für die Druckflüssig  keit in die Zylinder.

   Beim Eintritt der       Druckflüssigkeit    in die Presse durch den  Kanal<I>g</I> werden die Zylinder<I>a</I> auseinander  geschoben, bis dass die .Spannringe c in die  Nuten d der sie umgebenden Zylinder ein  dringen können und so den     Ausschub    begren  zen. Beim Zurückschieben der Zylinder, nach  Aufhören des     Pressdruckes,    durch die auf  ihnen ruhende Last werden die Spannringe c  zufolge der besonderen Ausbildung der Nu  ten d, sowie der Nuten,     in    denen die Spann  ringe in der eingeschobenen Stellung der Zy  linder gelagert sind, in diese wieder hinein  gedrückt.



      Hydraulic fluid press with several coaxially arranged cylinders. The present invention relates to a hydraulic fluid press, for example a pressurized water press, with several cylinders arranged one inside the other on the same axis. It is characterized in that a clamping ring embedded in its outer wall serves as a stop for each cylinder in its pushed out position;



  The subject of the invention is shown in an exemplary embodiment on the drawing. It shows: FIG. 1 the press in longitudinal section with cylinders pushed into one another, FIG. 2 the press with ejected cylinders, partly in longitudinal section; Figs. $ Through 5 show details.



  It means a the cylinders of the press. b is the outer wall of each cylinder, which is surrounded by another cylinder. c are clamping rings that are embedded in the outer wall of these cylinders. d are grooves in the inner wall of the cylinder, into which when pushed out. Position of the Zy cylinder the clamping rings c penetrate to limit the extension of the cylinder against each other. e are the cylinder seals that are located below the clamping rings c. f are the channels that allow the hydraulic fluid to get under the sealing rings. g is. the inlet channel for the hydraulic fluid in the cylinder.

   When the hydraulic fluid enters the press through the channel <I> g </I>, the cylinders <I> a </I> are pushed apart until the clamping rings c can penetrate into the grooves d of the cylinders surrounding them and thus limit the extension. When pushing back the cylinder, after cessation of the pressing pressure, due to the load resting on them, the clamping rings c according to the special design of the Nu th, as well as the grooves in which the clamping rings are stored in the inserted position of the Zy cylinder, in this pushed back in.
