Definitions

  • the present invention concerns a new utensil, specific for the disassembly and assembly of oleodynamic or air gaskets, like those applied onto oleo-hydraulic and pneumatic cylinders.
  • a utensil for removing O-rings and backup rings from perimetral cavaties of cylinders is known from US-A-481320.
  • the body of this utensil is provided with planes defining a laminar shape at the tip of the body.
  • two oppositely curved sections are provided which define a prying section that may penetrate between the O-ring respectively the backup ring and the perimetral cavity.
  • Figure 1 shows an axonometric view of a specific utensil for the disassembly and assembly of oleodynamic and air gaskets.
  • Figure 2 shows a vertical section of the new utensil according to the present invention.
  • Figure 3 shows a scheme of the functioning and the way of using the utensil according to the present invention.

Claims (1)

  1. Werkzeug zum Aus- und Einbauen von hydraulischen und pneumatischen Dichtungen, das sich folgendermaßen zusammensetzt:
    ein Griff (2);
    ein fest mit dem Griff (2) verbundener zylindrischer Körper (1);
    eine Verjüngung in der Nähe der vom Griff entfernten Spitze des Körpers, erzielt durch geneigte, einander gegenüberliegende Flächen (3, 4), die der zylindrischen Struktur des Körpers (1) an der Spitze des Körpers eine blattförmige Gestalt geben;
    eine erste Krümmung (5), die durch eine Neigung von 45° des Abschnitts des verjüngten Körpers definiert ist;
    eine zweite Krümmung (6), die durch eine Neigung zwischen der ersten Krümmung (5) und der Spitze in der der ersten Krümmung (5) entgegengesetzten Richtung definiert ist, wobei die Neigung, welche die zweite Krümmung definiert, geringer ist als die Neigung, die die erste Krümmung (5) definiert, und an der Spitze der Verjüngung erzeugt wurde, um ein Mittel zu erhalten, mit dem man zwischen die Dichtung (G) und die Umfangsnut (IP) eines hydraulischen oder pneumatischen Zylinders (C) eindringen kann, derart daß die genannte Dichtung, nachdem sie aufgrund ihrer Biegsamkeit ausgehoben wurde, herausgezogen werden kann, indem man sie die genannte Krümmung (5) entlang gleiten läßt.
