Abstract

Air pumps in the leisure sector have previously been designed as pistons or bellows pumps with mechanical actuation by hand or foot or with electric drive. These designs lead to a large expenditure of labour during pumping or, in the case of the electric drive, deliver insufficiently large volumes. The new pump does not need to be driven by human labour and delivers large volumes. The combustion gases or fresh gases of a combustion engine are used to drive a compressor. The pump finds application wherever hollow bodies are to be inflated at low pressure.

Description

Die Erfindung betrifft eine Luftpumpe nach dem Oberbegriff des Anspruchs 1.The invention relates to an air pump according to the Preamble of claim 1.

Luftpumpen sollen das Aufpumpen und/oder Entleeren von dafür vorgesehenen Gegenständen ermöglichen. Luftpumpen werden dort eingesetzt, wo keine stationäre Druckluftversorgung zur Verfügung steht. Ihre vorwiegende Anwendung finden sie im Freizeitbereich zum Beispiel zum Aufpumpen von Booten, Luftmatratzen und Reifen.Air pumps are designed to inflate and / or deflate enable the intended objects. Air pumps are used where there are no stationary ones Compressed air supply is available. Your they are mainly used in the leisure sector for example for inflating boats, air mattresses and tires.

Es ist bekannt, daß zur Erfüllung dieser Aufgabe Luftpumpen, die zum Aufpumpen von dafür vorgesehenen Gegenständen, wie sie hauptsächlich im Freizeitbereich vorkommen, zum Beispiel Schlauchboote, Luftmatratzen und Reifen, als Balgen- oder Kolbenpumpen ausgeführt werden. It is known to accomplish this task Air pumps designed to inflate them Objects such as those used mainly in the leisure sector occur, for example inflatables, air mattresses and tires, designed as bellows or piston pumps will.  

Balgenpumpen werden per Fuß oder per Hand betätigt. Kolbenpumpen für große Luftvolumina und geringem Druck werden von Hand betätigt. Kolbenpumpen für hohen Druck und kleine Lufvolumina werden elektrisch betrieben.Bellows pumps are operated by foot or by hand. Piston pumps for large air volumes and low pressure are operated by hand. Piston pumps for high pressure and small air volumes are operated electrically.

Die bekannten Systeme zum Aufblasen von Körpern mit großen Luftvolumina sind sehr arbeitsintensiv und/oder zeitintensiv. Zum anderen sind die bekannten Systeme in ihren Abmessungen sehr groß und sperrig.The known systems for inflating bodies with large air volumes are very labor intensive and / or time consuming. On the other hand, the known systems are in their dimensions are very large and bulky.

Der Erfindung liegt die Aufgabe zugrunde, das Pumpen per Hand oder Fuß durch automatisches Pumpen zu ersetzen und diesen Vorgang zu beschleunigen.The invention is based, pumping to be replaced by hand or foot with automatic pumping and accelerate this process.

Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is carried out in a generic facility by the characterizing features of claim 1 solved.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Pumpe nicht per Hand oder Fuß betrieben werden muß.The advantages achieved with the invention exist especially in that the pump is not by hand or Foot must be operated.

Der Pumpvorgang wird durch größere Pumpleistung gegenüber Balgen- und Kolbenpumpen, wie sie im Freizeit­ bereich benutzt werden, verkürzt.The pumping process is due to greater pumping power compared to bellows and piston pumps, as used in leisure time area used, shortened.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the Drawing shown and is closer below described.

Die Pumpe wird für den Aufpumpvorgang mit dem Auspuff­ stutzen eines Kraftfahrzeuges verbunden. Die unter Druck stehenden Abgase werden durch die Turbinenstufe 20 geleitet und treiben das Turbinenrad 25 an.The pump is connected to the exhaust port of a motor vehicle for the inflation process. The exhaust gases under pressure are passed through the turbine stage 20 and drive the turbine wheel 25 .

Das Turbinenrad 25 sitzt auf einer Welle 10, welche im Stator 15 gelagert ist, die ein auf ihr sitzendes Verdichterrad 35 antreibt.The turbine wheel 25 is seated on a shaft 10 which is mounted in the stator 15 and drives a compressor wheel 35 seated on it.

Das Verdichterrad 35 saugt Frischluft an und verdichtet diese im Verdichtergehäuse 30.The compressor wheel 35 draws in fresh air and compresses it in the compressor housing 30 .

Durch einen dafür vorgesehenen Anschluß 40 kann die komprimierte Luft abgenommen und weitergeleitet werden.The compressed air can be removed and passed on through a connection 40 provided for this purpose.
