Claims (10)

  1. Notfallvorrichtung umfassend einen hydropneumatischen Speicher, welcher mit einem hydraulischen Verbraucher (9, 14) über ein Ventil (6) verbunden ist, das einen standardmäßig geschlossenen Zustand aufweist, sowie eine Steuervorrichtung (7), welche dazu geeignet ist, das Ventil in einen durchlassenden Zustand umzuschalten, um die Versorgung des hydraulischen Verbrauchers durch den Druck des hydropneumatischen Speichers herbeizuführen, wobei der hydropneumatische Speicher einen Tank (1) umfasst, der mit Hydraulikflüssigkeit (12) gefüllt ist, in den ein Behälter (10) aus einem auf Dauer vollkommen gasdichten Material eingetaucht ist, der mit einem Druckgas gefüllt ist, wobei der Behälter derart ausgebildet ist, dass er nach Öffnen des Ventils (6) zerbricht, um den Gasdruck freizusetzen.
  2. Notfallvorrichtung gemäß Anspruch 1, wobei der Tank eine metallische Umhüllung (1) umfasst, welche ein geschlossenes Ende (2) und ein geöffnetes Ende (3) aufweist, welches, unter Versehung von Dichtungen, auf einem Endstück (4) verschraubt ist, welches eine Leitung (5) umfasst, die mit dem hydraulischen Verbraucher verbunden und mit dem Ventil (6) ausgestattet ist.
  3. Notfallvorrichtung gemäß Anspruch 2, wobei das Ventil über einen Stellhebel (7) gesteuert wird.
  4. Sicherheitsvorrichtung gemäß Anspruch 2 oder 3, wobei die metallische Umhüllung einen zylindrischen Querschnitt aufweist, das geschlossene Ende (2) der metallischen Umhüllung halbkugelformig und der auf Dauer vollkommen dichte Behälter (10) kugelförmig und in dem halbkugelförmigen Teil (2) der Umhüllung (1) untergebracht ist, an deren Form er sich anschmiegt.
  5. Notfallvorrichtung gemäß einem der Ansprüche 1 bis 4, wobei der Behälter ein Füllventil umfasst, welches von der Außenseite des Flüssigkeitstanks erreichbar ist.
  6. Sicherheitsvorrichtung gemäß einem der Ansprüche 1 bis 5, wobei der Verbraucher einen Zylinder umfasst.
  7. Sicherheitsvorrichtung gemäß Anspruch 6, wobei der Kolben (13) des Zylinders nach Öffnen des Ventils einen Stromschalter betätigt.
  8. Sicherheitsvorrichtung gemäß einem der Ansprüche 1 bis 5, wobei der Verbraucher einen Hydraulikmotor (14) umfasst.
  9. Sicherheitsvorrichtung gemäß Anspruch 8, wobei der Hydraulikmotor (14) nach Öffnen des Ventils die Turbine eines Hubschraubermotors betätigt.
  10. Notfallvorrichtung gemäß einem der Ansprüche 1 bis 9, wobei der Behälter (10) aus einem flexiblen und gasdichten Material hergestellt ist.
