Abstract

A balloon (3) is inserted into the pipeline (1) via an opening in the side, and is inflated by a pressure medium. The balloon is especially. used in the exhaust pipe or intake pipe (1b) of an IC engine. The balloon in the intake pipe is inflated by a pressure medium, which is generated by an electrically triggered propellant charge (5). The balloon is secured by a metal grating (4) downstream of an air filter (6).

Description

Die Erfindung bezieht sich auf einen Verschluß einer Rohrleitung.The invention relates to a closure of a pipeline.

Bei bestimmten Anwendungsfällen ist es erwünscht, eine Rohrleitung vorübergehend provisorisch zu verschließen, um das Eindringen von Feuchtigkeit, Staub oder derglei­ chen zu vermeiden. Bei fest montierten Rohrleitungen ist der nachträgliche Einbau ei­ nes Schiebers mit hohem Aufwand verbunden.In certain applications, it is desirable to temporarily use a pipeline temporarily seal to prevent the ingress of moisture, dust or the like to avoid chen. In the case of permanently installed pipelines, retrofitting is easy nes slide associated with high effort.

Der Erfindung liegt daher die Aufgabe zugrunde, den Verschluß einer Rohrleitung so zu gestalten, daß er mit einem Minimum an baulichem Aufwand bewerkstelligt wer­ den kann.The invention is therefore based on the object, the closure of a pipeline to design that he accomplishes with a minimum of structural effort that can.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß über eine seitliche Bohrung in der Rohrleitung ein Ballon eingeführt wird, und daß dieser Ballon innerhalb der Rohrleitung mittels eines Druckmediums aufgeblasen wird.According to the invention, this object is achieved in that a lateral bore a balloon is inserted in the pipeline and that this balloon is within the Pipeline is inflated using a pressure medium.

Durch den Ballon wird die Rohrleitung provisorisch verschlossen und ein Eindringen oder Durchtreten von Feuchtigkeit und dergleichen vermieden. Zur Freigabe der Rohrleitung wird der Ballon entlüftet und über die Bohrung wieder aus der Rohrlei­ tung entfernt und diese mit einem Stopfen verschlossen.The pipeline is temporarily closed by the balloon and penetration or the passage of moisture and the like is avoided. To release the The balloon is deflated by pipeline and then removed from the pipeline via the bore removed and sealed with a stopper.

Besonders vorteilhaft läßt sich der Ballon nach Anspruch 2 zum Verschließen einer Abgas- oder Ansaugleitung einer Brennkraftmaschine verwenden.The balloon according to claim 2 can be particularly advantageously used for closing one Use the exhaust or intake line of an internal combustion engine.

Eine vorteilhafte Weiterbildung der Erfindung kann Anspruch 3 entnommen werden. Wird der Ballon von einer Treibladung (Airbag-Prinzip) innerhalb einer Ansauglei­ tung einer Brennkraftmaschine aufgeblasen, kann er als Notstop verwendet werden. An advantageous development of the invention can be found in claim 3. The balloon is driven by a propellant charge (airbag principle) within an intake duct inflated by an internal combustion engine, it can be used as an emergency stop.  

Es ist dann vorteilhaft, den Ballon zusätzlich mit einem stabilen Metallgitter abzusi­ chern, um eine Beschädigung des Ballons durch den sich schlagartig ausbildenden, starken Unterdruck zu vermeiden.It is then advantageous to additionally cover the balloon with a stable metal grid to prevent the balloon from being damaged by the sudden to avoid strong negative pressure.

Ausfürungsbeispiele der Erfindung sind in Zeichnungen dargestellt. Es zeigt:Exemplary embodiments of the invention are shown in drawings. It shows:

Fig. 1 einen Ballon in einer Abgasleitung, Fig. 1 shows a balloon in an exhaust line,

Fig. 2 einen Ballon in einer Ansaugleitung. Fig. 2 shows a balloon in an intake pipe.

Nach Fig. 1 wird eine Rohrleitung 1 - hier eine Abgasleitung 1a - mit einer Bohrung 2 versehen durch die ein Ballon 3 eingeführt werden kann. Dieser wird anschließend mit einem Medium aufgeblasen und dadurch fest gegen die Innenwand der Rohrleitung 1 gepreßt. Die Rohrleitung ist damit verschlossen. . Here an exhaust pipe 1 a - - According to Fig 1 a conduit 1 is provided with a hole 2 through which a balloon 3 can be inserted. This is then inflated with a medium and thereby pressed firmly against the inner wall of the pipeline 1 . The pipe is now closed.

Ein derartiger vorübergehender Verschluß ist besonders vorteilhaft bei Abgasleitungen von Bootsmotoren anwendbar. Dort besteht das Problem, daß die Abgasleitung unter Wasser liegt, so daß die Abgase unterhalb der Wasserlinie austreten. Während der Be­ triebsruhe im Winter hat sich gezeigt, daß über die Abgasleitung Feuchtigkeit in den Motor eindringt und dort zu Schäden führt. Die nachträgliche Anbringung eines Schiebers zum Verschluß oder Abgasleitung ist aber mit hohen Kosten verbunden und wegen hoher Temperaturbelastung im Betrieb unzweckmäßig. Erfindungsgemäß wird daher vorgeschlagen die Abgasleitung mit dem aufblasbaren Ballon 3 zu verschließen.Such a temporary closure can be used particularly advantageously in exhaust pipes from boat engines. There is the problem that the exhaust pipe is under water, so that the exhaust gases emerge below the water line. During the operational silence in winter it was shown that moisture penetrates the engine via the exhaust pipe and causes damage there. The subsequent attachment of a slide to the closure or exhaust pipe is associated with high costs and is inappropriate due to high temperature loads during operation. According to the invention, it is therefore proposed to close the exhaust pipe with the inflatable balloon 3 .

Zur Wiederfreigabe der Rohrleitung 1 wird der Ballon 3 entlüftet und über die Boh­ rung 2 entfernt. Die Bohrung 2 kann mit einem Stopfen verschlossen werden.To release the pipeline 1 , the balloon 3 is vented and removed via the drilling 2 . The bore 2 can be closed with a stopper.

Es versteht sich von selbst, daß die Erfindung nicht nur auf Abgasleitungen beschrankt ist, sondern überall dort angewendet werden kann, wo die Randbedingungen so sind, daß der Ballon den vorübergehenden Verschluß einer Rohrleitung übernehmen kann.It goes without saying that the invention is not limited only to exhaust pipes but can be used wherever the boundary conditions are that the balloon can temporarily seal a pipeline.

Es wäre z. B. nach Anspruch 3 (Fig. 2) denkbar, einen derartigen Ballon 3 in einer Ansaugleitung 1b einer Brennkraftmaschine vorzusehen, um durch das Aufblasen des Ballons 3 bei einem Notstop eine starke Bremswirkung im Motor hervorzurufen. Der Ballon 3 wird dabei stromab eines Luftfilters 6 angeordnet. Der Ballon 3 kann durch eine elektrisch ausgelöste Treibladung 5 aufgeblasen werden, ähnlich dem Prinzip ei­ nes Airbags. Durch die schlagartige Unterbrechung der Motor-Aspiration baut sich stromabwärts schlagartig ein extremer Unterdruck auf. Das in der Ansaugleitung 1b befindliche Metallgitter 4 fangt den aufgrund dieses Unterdruckes sich stark anlegenden Ballon 3 ab und fixiert diesen in der gewünschten Position.It would be e.g. B. according to claim 3 ( Fig. 2) conceivable to provide such a balloon 3 in an intake pipe 1 b of an internal combustion engine to cause a strong braking effect in the engine by inflating the balloon 3 during an emergency stop. The balloon 3 is arranged downstream of an air filter 6 . The balloon 3 can be inflated by an electrically triggered propellant charge 5 , similar to the principle of an airbag. Due to the sudden interruption of the motor aspiration, an extreme negative pressure suddenly builds up downstream. The metal grid 4 located in the suction line 1 b intercepts the balloon 3 , which is strongly applied due to this negative pressure, and fixes it in the desired position.
