Description

Drehkolbenpumpe mit seitlichen Abdichtungsscheiben, die durch Federdruck an die Zylinder-Stirnflächen angedrückt werden Bei Drehkolbenpumpen, welche für geringe Druckhöhen gebaut sind, ist es notwendig, in ,lie Druckleitung ein Sicherheitsventil einzuhauen, um Beschädigungen oder Zerstörungen der Pumpe vorzubeugen, falls die Druckleitung geschlossen wird. Hierbei wird gewöhnlich ,der Überlauf des Sicherheitsventiles durch eine Umgangsleitung in die Saugleitung rückgeführt. Diese Anordnung ist umständlich, teuer und Raum im Anspruch nehmend.Rotary lobe pump with lateral sealing washers, which are spring-loaded be pressed against the cylinder end faces low pressure heads are built, it is necessary to put a safety valve in the pressure line to prevent damage or destruction of the pump, if the Pressure line is closed. This usually involves the overflow of the safety valve returned to the suction line through a bypass line. This arrangement is cumbersome, expensive and space-consuming.

Diesem Nachteil hilft die nachstehend beschriebene Erfindung dadurch ab, daß die bekannten seitlichen Abdichtungsscheiben, die durch Federdruck an die Zylinder-Stiralächen angedrückt werden, als Sicherheitsventil wirken, indem die Scheiben unter einen solchen Federdruck gesetzt werden, daß sie sich bei unerwünschtem Überdruck zwecks Verbindung der Druck- und Saugseite von ihrem Sitz auf der Zylinder-Stirnfläche abheben.The invention described below thereby helps this disadvantage from that the well-known side sealing washers, which by spring pressure to the Cylinder end faces are pressed, act as a safety valve by the Discs are placed under such a spring pressure that they are undesirable Overpressure for the purpose of connecting the pressure and suction side from their seat on the cylinder face lift up.

In den Abbildungen ist ein Ausführungsbeispiel .dargestellt. Es zeigt: Abb. r eine Drehlcolbenpumpe bei abgenommenem Deckel, Abb. 2 einen Längsschnitt durch die Pumpe. An dem einen Ende des Zylinders wird der Arbeitsraum a in bekannter Weise durch eine Scheibe b abgeschlossen, welche durch eine Feder c, deren Druck regelbar sein kann, auf ihren von der Stirnfläche des Zylinders gebildeten Sitz d amgepreßt wird. Die Platte b kann auch beiderseits des Zylinderraumes angebracht werden. Überschreitet der Druck die ihm zugemessene Höhe, so gibt die auf den gewünschten Druck eingestellte Feder c nach, die Scheibe b wird von ihrem Sitz abgehoben, und der Überdruck gelangt unmittelbar vom Druck zum Saugraum der Pumpe.An exemplary embodiment is shown in the figures. It shows: Fig. R a rotary piston pump with the cover removed, Fig. 2 a longitudinal section through the pump. At one end of the cylinder, the working space a is closed in a known manner by a disk b which is pressed onto its seat d formed by the end face of the cylinder by a spring c, the pressure of which can be regulated. The plate b can also be attached on both sides of the cylinder space. If the pressure exceeds the level assigned to it, the spring c set to the desired pressure gives way, the disc b is lifted from its seat, and the overpressure reaches the suction chamber of the pump directly from the pressure.
