Description

Drebkolbenpumpe Bekannt sind Drehkolbenpumpen, wie in Abb. r und z ohne Kolbentrommel und Kolben dargestellt, deren. Ein- und Austrittskanäle durch den Arbeitszylinder hindurchgehen.Rotary lobe pumps Rotary lobe pumps are known, as shown in Fig. R and z Shown without piston drum and piston, their. Inlet and outlet channels through go through the working cylinder.

Alle bisher bekannten, die Gleitfläche des Arbeitszylinders unterbrechenden Kanäle, gleichviel ob sie eine runde, elliptische, rechteckige oder sonstige Form besitzen und wie auch ihre Lage und Anordnung ist, besitzen den Nachteil, daß sie die Gleitfläche in bezug auf die Zylinderlänge nur teilweise durchschneiden. Dies hat zur Folge, daß sich über den durchbrochenen Stellen die Kolben beim Darübergleiten nicht abnutzen, so daß bei weiterem Lauf die hinter den durchbrochenen Stellen durchlaufene Zylindergleitfläche vermehrt abgenutzt wird, wodurch die Zylinderfläche in Richtung der Mantellinien in demselben Maße eine Aushöhlung erfährt, als der über den durchbrochenen Stellen nicht stattgehabten Kolbenabnutzung entspricht. Eingelaufene verbrauchte Kolben können ohne Nacharbeitung des Arbeitszylinders nicht durch neue ersetzt werden, weil diese in Richtung der Mantellinien gerade sind, . sich der Aushöhlung nicht anpassen und somit nicht abdichten. Diesem Nachteil hilft die vorliegende Erfindung dadurch ab, daß die Ein- und Austrittskanäle, welche die Zylindergleitfläche durchschneiden, in der Drehrichtung in bekannter Weise gleich, breit, zugleich aber vollständig durch die ganze Länge des Arbeitszylinders hindurchgeführt werden.All previously known, interrupting the sliding surface of the working cylinder Channels, regardless of whether they are round, elliptical, rectangular or any other shape have and what their location and arrangement is, have the disadvantage that they cut through the sliding surface only partially in relation to the cylinder length. this As a result, the pistons slide over the perforated points do not wear out, so that when you continue to run, the areas behind the perforated areas are traversed Cylinder sliding surface is increasingly worn, causing the cylinder surface in the direction the surface lines are hollowed out to the same extent as the one above the openwork Places corresponds to piston wear that has not taken place. Consumed Pistons cannot be replaced with new ones without reworking the working cylinder, because these are straight in the direction of the surface lines,. not the hollowing out adapt and therefore not seal. The present invention helps to overcome this disadvantage from the fact that the inlet and outlet channels, which cut through the cylinder sliding surface, in the direction of rotation in a known manner the same, wide, but at the same time complete be passed through the entire length of the working cylinder.

Abb.3 zeigt den Längsschnitt eines Arbeitszylinders mit dem einen in Richtung a überall gleich breiten, die ganze Zylinderlänge durchschneidenden Kanal. Es erhellt ohne weiteres, daß ein über diesen Kanal gleitender Kolben an jedem Punkt seiner Gleitfläche genau die gleiche Abnutzung erfährt, dadurch seine gerade Gleitfläche beibehält und damit auch die gerade Zylindermantelfläche erhalten bleibt.Fig.3 shows the longitudinal section of a working cylinder with one in direction a of the same width everywhere, cutting through the entire length of the cylinder Channel. It is readily apparent that a piston sliding over this channel is starting every point of its sliding surface experiences exactly the same wear, thereby its Maintains a straight sliding surface and thus also preserves the straight cylinder jacket surface remain.
