PATENTAMT.PATENT OFFICE.
Der für Membran-Flüssigkeitsmesser für tropfbare und gasförmige Flüssigkeiten sowie auch für Pumpen bestimmte Kolben A ist aus Gufseisen hergestellt und rings mit einer Nuth B versehen, in welche die Membran C eingelegt ist. Der Kolben A läuft in einer Führung D, die mit dem Gehäuse E aus einem Stück gegossen ist, und in einer Führung F, welche durch Schraubenbolzen mit jener verbunden wird und gleichzeitig mit jener die Membran C festhält bezw. führt. Die Abdichtung des Kolbens wird durch die Membran C folgendermafsen bewerkstelligt: Beim Vor- bezw. Rückgehen des Kolbens legt sich die Membran einmal an die Vorseite und das andere Mal an die Rückseite der Nuth B. Die Kolbenstange G ist mit dem Kolben A durch Konus und Schraubenmutter fest verbunden und führt sich an dem anderen Ende in dem Deckel H. The piston A intended for membrane liquid meters for drip and gaseous liquids as well as for pumps is made of cast iron and is provided with a groove B all around, into which the membrane C is inserted. The piston A runs in a guide D, which is cast in one piece with the housing E , and in a guide F, which is connected to that by screw bolts and at the same time holds the membrane C in place. leads. The sealing of the piston is accomplished by the membrane C as follows: When the piston goes back, the membrane lies on the front side and the other time on the back of the groove B. The piston rod G is firmly connected to the piston A by a cone and screw nut and is guided at the other end in the cover H.
Es kann auch folgende Einrichtung getroffen sein: Der Kolben A ist aus Gufseisen hergestellt und mit# einem Kolbendeckel versehen. Zwischen dem Kolbendeckel und dem Kolbenboden führt sich die Membran C, welche an ihrem Rande in einer in der Kolbenführung D F angebrachten Nuth liegt. In diesem Falle erhält der Kolben seine Abdichtung dadurch, dafs beim Vor- bezw. Rückgange des Kolbens die Membran sich einmal an die Vorderseite, das andere Mal an die Rückseite der in der Kolbenführung angebrachten Nuth legt.It may be taken the following means: the piston A is made of Gufseisen and provided a piston head with #. The membrane C runs between the piston cover and the piston head and lies at its edge in a groove made in the piston guide DF . In this case, the piston obtains its seal by the fact that when it is in front or behind. When the piston moves back, the membrane is placed on the front side, the other time on the back of the groove made in the piston guide.
Schliefslich kann die Einrichtung noch so getroffen sein, dafs der Kolben mit einem Kolbendeckel versehen ist und gleichzeitig die Kolbenführung D F aus zwei Theilen besteht.Finally, the device can also be designed in such a way that the piston is provided with a piston cover and at the same time the piston guide DF consists of two parts.
