Membranpumpe. Patentiert im Deutschen Reiche vom 22. Mai 1913 ab.Diaphragm pump. Patented in the German Empire on May 22, 1913.
Gegenstand der Erfindung ist eine Membranpumpe, die besondere Vorteile für die Verwendung bei Staubsaugevorrichtungen besitzt. Der Erfindung liegt der Gedanke zugrunde, daß um ein sich drehendes Exzenter im Kreise herum vier oder mehr Membranen angeordnet sind, die von dem Exzenter bei einer Umdrehung einmal hin und zurück bewegt werden, also einmal drücken und einmal saugen.The invention relates to a diaphragm pump which has particular advantages for its use in vacuum cleaning devices. The invention is based on the idea that a rotating eccentric in a circle around four or more diaphragms are arranged by the eccentric at one revolution be moved back and forth once, i.e. press once and suck once.
ίο So sind bei dem dargestellten Ausführungsbeispiel um ein Exzenter α herum, das auf der Welle eines Elektromotors h aufgekeilt ist, vier Membranen b, b, b, b (vgl. Fig. i) angeordnet. Auf diese Membranen wirkt das Exzenter α mittelbar ein, dadurch, daß es von einem quadratischen Rahmen a1 umgeben ist, an dem Rollen c, c, c, c anliegen. Diese Rollen sind mit den Tellern b1 der zugehörigen Membranen verbunden; sie sind auf Schienen d, d gelagert, die je zwei gegenüberliegende Membranen verbinden. Das Rahmenstück a1 ist innen zu einem Kugellager für den Umfang des Kreisexzenters α ausgebildet; es wird von diesem ständig bewegt und überträgt die Bewegung auf die Membranen.In the illustrated embodiment, four membranes b, b, b, b (see FIG. i) are arranged around an eccentric α which is keyed onto the shaft of an electric motor h. The eccentric α acts indirectly on these membranes, in that it is surrounded by a square frame a 1 on which rollers c, c, c, c rest. These roles are connected to the plates b 1 of the associated membranes; they are mounted on rails d, d , which each connect two opposing membranes. The frame piece a 1 is formed inside to form a ball bearing for the circumference of the circular eccentric α ; it is constantly moved by it and transfers the movement to the membranes.
Die Membranen schließen Öffnungen eines Gehäuses i nach innen ab; sie werden durch Deckel β am Rande festgehalten. Diese Deckel sind so geformt, daß sie das hin und her gehende Spiel der Membran gestatten; ihre äußere Form entspricht also der einen Endstellung der Membran. In den Deckeln e ist je ein Saugventil f und ein Druckventil g untergebracht, die aus elastischem Material bestehen und als Lippenventile ausgebildet sind.The membranes close openings of a housing i on the inside; they are held at the edge by cover β. These covers are shaped in such a way that they allow the diaphragm to move back and forth; its outer shape therefore corresponds to one of the end positions of the membrane. A suction valve f and a pressure valve g , which are made of elastic material and are designed as lip valves, are housed in each of the covers e.
Die Saugventile f sitzen auf Öffnungen der Zwischenwand k des umschließenden Gehäuses I; sie entnehmen die Luft aus dem Staubsammelraum m; diese durchströmt vorher entsprechende Filter, so daß sie aus dem Druckventil g gereinigt in den Raum η und von da ins Freie tritt.The suction valves f sit on openings in the partition k of the enclosing housing I ; they take the air from the dust collection space m; this flows through appropriate filters beforehand, so that it exits the pressure valve g, cleaned, into space η and from there into the open.
Bei den bisher verwendeten, mehrfach wirkenden Membranpumpen für Staubsauger ist die Anordnung entweder so getroffen, daß, durch eine Kurbel angetrieben, mehrere auf einer Stange sitzende Membranen die Arbeitsräume bilden, oder daß eine mehrfach gekröpfte Kurbelwelle die nebeneinander angeordneten Membranen bewegt. Im ersteren Falle arbeitet die Pumpe stoßweise, da bei einer Umdrehung der Kurbelwelle von sämtlichen Membranen gleichzeitig die Luft einmal angesaugt und dann ausgestoßen wird. Bei der zweitgenannten Einrichtung ist der Raumbedarf der Maschine groß und die Verwendung einer gekröpften Welle umständlich und teuer.In the case of the multiple-acting diaphragm pumps for vacuum cleaners used so far the arrangement either made so that, driven by a crank, several on a rod seated membranes form the working spaces, or that a multi-cranked one Crankshaft moves the membranes arranged next to one another. In the former Case, the pump works intermittently, since with one revolution of the crankshaft of all Membranes at the same time the air is sucked in once and then expelled. In the case of the second device mentioned, the space requirement is the machine is large and the use of a cranked shaft is cumbersome and expensive.
Dagegen ist beim Erfindungsgegenstande die Ausführung sehr einfach, dabei ist der Raumbedarf gering, weshalb sich die Maschine besonders gut als transportable Staubsauge vorrichtung ausbilden läßt. Dadurch, daß vonIn contrast, the subject matter of the invention is very simple to carry out, while the space requirement is important low, which is why the machine is particularly good as a portable vacuum cleaner device can be trained. Because of
den im Kreise angeordneten Membranen immer mehrere ansaugen und andere drücken, wird der Luftstrom ein sehr gleichmäßiger. Die Kupplung zwischen Pumpe und Motor ist infolge der Membranen eine elastische, und jede besondere Lagerung der Zwischengetriebe fällt fort.the diaphragms arranged in a circle will always suck in several and press others the airflow is very even. The coupling between pump and motor is a result the diaphragms are elastic, and every special bearing of the intermediate gear falls away.
