Definitions

  • the invention relates to a protective device for gas containers, in particular for gas containers of motor vehicles and boats, according to the preamble of claim 1.
  • Such a protective device is from the EP 0 707 174 A1 and the DE 86 19 754 U1 known.
  • Motor vehicles including motorcycles as well as boats with internal combustion engines are increasingly operated with LPG and therefore require a gas tank, which replaces the previous tank for fuels such as gasoline or diesel oil.
  • the EP 0 707 174 A1 shows a gas container, which is surrounded by a protective jacket, which consists of shock-absorbing plastic material.
  • the protective jacket has a plurality of openings extending therethrough, which serve as drainage openings for gas and liquid.
  • the DE 86 19 754 U1 shows a compressed gas cylinder whose outer surface is partially provided with a bandage, having the venting channels extending through the bandage.
  • the DE 197 41 767 A1 shows a fuel tank for a motor vehicle for refueling with LPG, which should better use the given installation space in a motor vehicle, that a cavity of the central part has a polygonal cross-section.
  • the DE 198 16 651 C2 describes a tank for liquefied petroleum gas as a fuel in motor vehicles, in which the suspension is realized by a support tube extending through the tank.
  • the tank has a vacuum insulation surrounding it.
  • the support tube is made of heat-insulating fiber composite material.
  • the DE 201 02 209 U1 describes a gas-tight plastic container for motor vehicles, which has a removable sheath for inspection purposes.
  • the DE 103 22 117 A1 shows a liquefied petroleum gas fuel tank for motor vehicles with an inner container, a surrounding outer container and a lying between these two containers isolation space.
  • two heat conductors are arranged, which open into the inner container through each opening formed in an upper and in a lower wall region of the inner container. The heat conductors should cause a temperature compensation between the lower and upper portions of the inner container.
  • the 100 58 632 B4 shows a protective device for compressed gas containers, such.
  • Compressed gas cylinders or pressure cans with a protective body having an inner shell and an outer shell, the space is partially or completely foamed.
  • a compressed gas cylinder or pressure can be used in the interior of the inner shell.
  • the inner and outer shells can be made of metal or plastic, wherein the plastic can be reinforced by glass fiber, mineral fiber or carbon fiber.
  • the inner and outer shell each consist of several shell parts, which are connected by gluing, by plug connection or fitting together.
  • the DE 10 2004 044 541 A1 shows a pressurized gas container with a rigid inner container and a bullet-proof jacket surrounding this outside of an elastic and highly tensile material in the circumferential direction.
  • the elastic jacket is intended to cause the kinetic energy of projectiles to be absorbed or deflected in the circumferential direction by deformation of the jacket.
  • the high tensile strength of the material in the circumferential direction is intended to prevent bursting of the shell and thus of the entire compressed gas tank.
  • the jacket is spaced from the outer surface of the inner container, wherein the space between the inner container and jacket can be filled with resilient material, such as with foam material.
  • the main purpose of this compressed gas tank is the storage of oxygen in airplanes.
  • the protective device is at least in two parts, the two parts being separable from one another to form a gas container, e.g. a gas bottle to be able to use.
  • a plurality of container suspensions are mounted on the protective jacket, which are, for example threaded sleeves, which are either attached only to the protective jacket or even protrude through the intermediate space and secured to an inner container.
  • a protective jacket 5 is arranged at a distance, wherein a gap between the outer wall of the gas container 1 and the inner wall of the protective jacket 5 is filled with a damping medium as a damping layer 6.
  • the ventilation shaft is to be connected to outside air when installed in enclosed spaces of motor vehicles.
  • the gas tank When used in motor vehicles, the gas tank is permanently installed as a "tank".
  • the protective device according to the invention has a plurality of container suspensions 11, which are embodied, for example, as threaded sleeves which can extend into the damping medium and can also be fastened to the gas container 1. If the gas container 1 is made of metal, then these threaded sleeves can be welded or soldered to the outer wall of the gas container.
  • Fig. 2 The variant of Fig. 2 is intended for the use of usable gas cylinders.
  • a conventional gas cylinder can be inserted into the protective device.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is achieved by the features specified in claim 1. Advantageous embodiments and further developments of the invention can be found in the dependent claims.

Kurz zusammengefaßt schafft die Erfindung eine Schutzeinrichtung für Gasbehälter, insbesondere für Gasbehälter von Kraftfahrzeugen und Booten mit einem Schutzmantel, der mehrwandig ausgeführt ist und sehr gute Aufprallschutzeigenschaften hat. Der Schutzmantel umgibt den eigentlichen Gasbehälter in einem Abstand, so daß ein Zwischenraum gebildet ist, der mit einem Dämpfungsmaterial gefüllt ist. Das Dämpfungsmaterial ist gasdurchlässig. Es kann aus offenporigem Schaum bestehen oder auch aus einer losen Schüttung von elastischem Material, welches gute stoß- und schlagabsorbierende Eigenschaften hat. Vorzugsweise ist dieses Material nicht brennbar. Der Schutzmantel hat mindestens eine in die Dämpfungsschicht hineinragende Öffnung, in die eine Hülse mit radialen Löchern eingesetzt ist, so daß aus dem Innenbehälter austretendes Gas zur Umgebungsluft abgeleitet werden kann und sich nicht in höherer Konzentration in dem Zwischenraum ansammeln kann.Briefly summarized, the invention provides a protective device for gas containers, in particular for gas containers of motor vehicles and boats with a protective jacket that is multi-walled and has very good impact protection properties. The protective jacket surrounds the actual gas container at a distance, so that a gap is formed, which is filled with a damping material. The damping material is gas permeable. It may consist of open-pored foam or of a loose bed of elastic material, which has good shock and impact absorbing properties. Preferably, this material is not combustible. The protective jacket has at least one opening projecting into the damping layer into which a sleeve with radial holes is inserted, so that gas emerging from the inner container can be diverted to the ambient air and can not accumulate in the intermediate space in a higher concentration.

Bei Verwendung in Booten ist darauf zu achten, daß diese mindestens eine Öffnung oberhalb der Wasserlinie angeordnet ist und entweder durch die Einbaulage des Gasbehälters oder durch einen Verbindungsschlauch sichergestellt ist, daß diese Öffnung nach Außenbord geführt ist.When used in boats, it must be ensured that this is arranged at least one opening above the waterline and secured either by the installation position of the gas container or by a connecting hose is that this opening is guided outboard.

Nach einer Variante der Erfindung ist die Schutzeinrichtung doppelwandig. Nach einer anderen Variante bildet eine Innenwand gleichzeitig den Gasbehälter.According to a variant of the invention, the protective device is double-walled. According to another variant, an inner wall simultaneously forms the gas container.

Nach einer Variante ist die Schutzeinrichtung mindestens zweiteilig, wobei die beiden Teile voneinander trennbar sind, um einen Gasbehälter, wie z.B. eine Gasflasche, einsetzen zu können.According to a variant, the protective device is at least in two parts, the two parts being separable from one another to form a gas container, e.g. a gas bottle to be able to use.

Nach einer Weiterbildung der Erfindung sind am Schutzmantel mehrere Behälteraufhängungen angebracht, die beispielsweise Gewindehülsen sind, die entweder nur am Schutzmantel befestigt sind oder auch durch den Zwischenraum hindurchragen und an einem Innenbehälter befestigt sind.According to a development of the invention, a plurality of container suspensions are mounted on the protective jacket, which are, for example threaded sleeves, which are either attached only to the protective jacket or even protrude through the intermediate space and secured to an inner container.

Im folgenden wird die Erfindung anhand von Ausführungsbeispielen im Zusammenhang mit der Zeichnung ausführlicher erläutert. Es zeigt:

Fig. 1
einen Querschnitt einer Schutzeinrichtung nach einem ersten Ausführungsbeispiel der Erfindung; und
Fig. 2
eine Schutzeinrichtung nach einem zweiten Ausführungsbeispiel der Erfindung.
In the following the invention will be explained in more detail by means of exemplary embodiments in conjunction with the drawing. It shows:
Fig. 1
a cross section of a protective device according to a first embodiment of the invention; and
Fig. 2
a protective device according to a second embodiment of the invention.

Fig. 1 zeigt einen Gasbehälter 1, dessen Innenraum 2 mit Flüssiggas befüllbar ist. Der Gasbehälter 1 hat einen Befüll- und Entleerschacht 3, der hier ein Innengewinde 4 aufweist, in das ein herkömmliches Absperrventil einschraubbar ist. An dieses nicht dargestellte Absperrventil ist eine Rohrleitung anschließbar, die zu dem Gasverbraucher, insbesondere einer Verbrennungskraftmaschine führt. Fig. 1 shows a gas container 1, the interior 2 can be filled with liquid gas. The gas container 1 has a filling and emptying shaft 3, which here has an internal thread 4 into which a conventional shut-off valve can be screwed. At this shut-off valve, not shown, a pipe is connected, which leads to the gas consumer, in particular an internal combustion engine.

Rings um den Gasbehälter 1 ist in einem Abstand ein Schutzmantel 5 angeordnet, wobei ein Zwischenraum zwischen der Außenwandung des Gasbehälters 1 und der Innenwandung des Schutzmantels 5 mit einem Dämpfungsmedium als Dämpfungsschicht 6 befüllt ist.Around the gas container 1, a protective jacket 5 is arranged at a distance, wherein a gap between the outer wall of the gas container 1 and the inner wall of the protective jacket 5 is filled with a damping medium as a damping layer 6.

Das Dämpfungsmedium kann ein offenporiger Kunstharzschaum sein. Er kann auch aus einer losen Schüttung eines Dämpfungsmateriales bestehen. Das Material muß gute stoßdämpfende und schockabsorbierende Eigenschaften haben. Zusätzlich ist es wünschenswert, wenn das Material gute Wärmedämmungseigenschaften hat, um eine Erwärmung des Gasbehälters 1 bei höheren Außentemperaturen zu unterbinden. Auch soll das Dämpfungsmaterial nicht brennbar sein. Beispielsweise kommen als Dämpfungsmaterial in Frage: Mineralwolle, Glaswolle, eine Schüttung aus Perlitkörnern und sonstige bekannte Materialien, die die stoßdämpfende, schockabsorbierende, wärmedämmende und nicht brennbare Eigenschaft haben.The damping medium may be an open-cell synthetic resin foam. It can also consist of a loose bed of a damping material. The material must have good shock-absorbing and shock-absorbing properties. In addition, it is desirable if the material has good thermal insulation properties to prevent heating of the gas container 1 at higher outside temperatures. Also, the damping material should not be flammable. For example, as a damping material in question: mineral wool, glass wool, a bed of pearlite grains and other known materials that have the shock-absorbing, shock-absorbing, heat-insulating and non-combustible property.

Der Schutzmantel 5 besteht ebenfalls aus elastischem Material, wobei sich besonders in Kunstharz eingebettete Fasern eignen, wie z.B. Glasfasern oder Carbonfasern, die sich bei mechanischer Belastung, wie z.B. einem Aufprall auf einen harten Gegenstand, verformen und damit Verformungsenergie auf das Dämpfungsmedium übertragen und damit den Gasbehälter 1 vor direkter Krafteinwirkung schützen.The protective jacket 5 is also made of elastic material, with fibers particularly embedded in synthetic resin, such as e.g. Glass fibers or carbon fibers which, under mechanical stress, e.g. an impact on a hard object, deform and thus transmit deformation energy to the damping medium and thus protect the gas container 1 from direct force.

Der Gasbehälter 1 kann aus Stahl und insbesondere Edelstahl bestehen. Er kann aber auch aus gasdichtem Kunststoff gefertigt sein.The gas container 1 may be made of steel and in particular stainless steel. But it can also be made of gas-tight plastic.

In der Praxis ist nicht auszuschließen, daß der Gasbehälter 1 undicht wird, sei es durch Korrosion, Materialermüdung oder auch bei sehr starker Krafteinwirkung durch Bruch. Damit sich in dem mit dem Dämpfungsmedium gefüllten Zwischenraum keine größeren Gasmengen ansammeln, ist vorgesehen, daß der Schutzmantel 5 mindestens eine, in der Praxis mehrere Entlüftungsschächte als Öffnungen 7 aufweist, die sich in das Dämpfungsmedium hinein erstrecken. Der Entlüftungsschacht ist eine Hülse 8, die mehrere radiale Löcher 9 aufweist. Der Entlüftungsschacht ist - bezogen auf die normale Einbaulage - im unteren Bereich und vorzugsweise am Boden 10 des Schutzmantels 5 angeordnet, damit im Zwischenraum, der das Dämpfungsmedium enthält, befindliches Gas durch Schwerkraftwirkung abfließen kann. Durch den Entlüftungsschacht wird auch verhindert, daß sich im Zwischenraum zwischen dem Gasbehälter 1 und dem Schutzmantel 5 ein Überdruck gegenüber Atmosphärendruck aufbauen kann.In practice, it can not be ruled out that the gas container 1 will leak, be it due to corrosion, material fatigue or even under very strong force breakthrough. So that accumulate in the space filled with the damping medium space no larger amounts of gas, it is provided that the protective jacket 5 has at least one, in practice a plurality of vent shafts as openings 7, which extend into the damping medium. The vent shaft is a sleeve 8, which has a plurality of radial holes 9. The vent shaft is - in relation to the normal installation position - arranged in the lower region and preferably at the bottom 10 of the protective jacket 5, so that in the intermediate space containing the damping medium, located gas can flow by gravity. Through the vent shaft is also prevented that can build up in the space between the gas tank 1 and the protective jacket 5 over atmospheric pressure.

Bei Einbau in Booten ist darauf zu achten, daß der Entlüftungsschacht oberhalb der Wasserlinie liegt und über eine Rohrleitung oder einen Schlauch mit "Außenbords" verbunden ist, damit sich abfließendes Gas nicht im Bootsinneren ansammeln kann.When installing in boats, make sure that the exhaust duct is above the waterline and is connected by a pipe or hose to "outboard", so that any escaping gas can not accumulate inside the boat.

In analoger Weise ist beim Einbau in geschlossenen Räumen von Kraftfahrzeugen der Entlüftungsschacht mit Außenluft zu verbinden.In an analogous manner, the ventilation shaft is to be connected to outside air when installed in enclosed spaces of motor vehicles.

Bei Verwendung in Kraftfahrzeugen wird der Gasbehälter als "Tank" fest eingebaut. Zu diesem Zweck hat die Schutzeinrichtung nach der Erfindung mehrere Behälteraufhängungen 11, die beispielsweise als Gewindehülsen ausgeführt sind, die sich in das Dämpfungsmedium hinein erstrecken können und auch am Gasbehälter 1 befestigt sein können. Ist der Gasbehälter 1 aus Metall, so können diese Gewindehülsen an der Außenwand des Gasbehälters angeschweißt oder angelötet sein.When used in motor vehicles, the gas tank is permanently installed as a "tank". For this purpose, the protective device according to the invention has a plurality of container suspensions 11, which are embodied, for example, as threaded sleeves which can extend into the damping medium and can also be fastened to the gas container 1. If the gas container 1 is made of metal, then these threaded sleeves can be welded or soldered to the outer wall of the gas container.

Die Variante der Fig. 2 ist für die Verwendung von einsetzbaren Gasflaschen vorgesehen. Hier kann bei Bedarf eine herkömmliche Gasflasche in die Schutzeinrichtung eingesetzt werden. Diese Gasflasche ist nur schematisch dargestellt. Sie enthält einen Innenraum 2 und einen Befüll- und Entleerschacht 3. Die Schutzeinrichtung ist in diesem Ausführungsbeispiel doppelwandig ausgeführt. Sie hat eine Innenwand 12a, 12b, einen Schutzmantel 5a, 5b und in einem Zwischenraum zwischen der Innenwand und dem Schutzmantel das Dämpfungsmedium 6a, 6b. Zum Austauschen des Gasbehälters 1 ist die Schutzeinrichtung in zwei Teile 13 und 14 aufgeteilt, die über ein Scharnier 15 miteinander verbunden sind, so daß das Oberteil 14 aufgeklappt werden kann. Ist die Gasflasche eingesetzt, so können die beiden Teile 13 und 14 durch einen herkömmlichen Spannverschluß 16 miteinander verbunden werden.The variant of Fig. 2 is intended for the use of usable gas cylinders. Here, if required, a conventional gas cylinder can be inserted into the protective device. This gas cylinder is shown only schematically. It contains an interior 2 and a filling and emptying shaft 3. The protective device is designed double-walled in this embodiment. It has an inner wall 12a, 12b, a protective jacket 5a, 5b and in a space between the inner wall and the protective jacket, the damping medium 6a, 6b. To replace the gas container 1, the protective device is divided into two parts 13 and 14, which are connected to each other via a hinge 15, so that the upper part 14 can be opened. If the gas cylinder is used, the two parts 13 and 14 can be connected to one another by a conventional tension lock 16.

Der Entlüftungsschacht als Hülse 8 oder die Entlüftungsschächte durchdringen bei diesem Ausführungsbeispiel auch die Innenwand 12a, damit der den Gasbehälter 1 aufnehmende Raum nach außen entlüftet ist.The vent shaft as a sleeve 8 or the vent shafts penetrate in this embodiment, the inner wall 12a, so that the gas container 1 receiving space is vented to the outside.
