Description

Die' Erfindung betrifft eire Drehkolbenpumpe mit einem in einem Zylinder exzentrisch umlaufenden Drehkolben und mit in beiden gelagerten, die Arbeitsräume abgrenzenden Flügeln, wobei als Lagerstelle im Drehkolben Gleitbacken angeordnet sind.The 'invention relates to a rotary lobe pump with one in a cylinder eccentric rotating pistons and the working spaces in both delimiting wings, with sliding blocks arranged as a bearing in the rotary piston are.

Bei den bekannten Drebkolbenpumpen mit die Arbeitsräume abgrenzenden Flügeln sind diese in dem exzentrisch zum Kolben gelagerten, angetriebenen Zylinder in Schlitzen geführt. Die Flügel dichten am Zylindermantel durch bewegliche Gleitbacken ab und werden durch Ringnuten, in die sie seitlich eingreifen, -an der Zylinderwand festgehalten. Hierbei erzeugt der einseitige Flüssigkeitsdruck auf die Flügel in den Schlitzen des Zylinders einen erheblichen Arbeitswiderstand. Eine starke Abnutzung der Flügelgleitbacken ist nicht zu verhindern, wodurch die Leistung verhältnismäßig rasch absinkt. . -So ist eine Ausbildung bekannt; bei der zwischen einem. als Hohlzylinder ausgebildeten Drehkolben und einer Innenhülse; die in diesem exzentrisch verstellbar umläuft, ein Hohlraum entsteht, der durch Pendelschieber abgegrenzt wird, die einerseits im Drehkolben angelenkt und - andererseits in der Innenhülse - in halbkreisförmigen Gleitbacken -gelenkig geführt werden. Bei dieser Anordnung müssen die radialen Bewegungen der Schieber in den Gleitbacken unter dem gesamten auf ihnen lastenden Flüssigkeitsdruck ausgeführt werden, was nur unter erheblichen Reibungsverlusten möglich ist..In the known rotary piston pumps with delimiting the working spaces These are wings in the driven cylinder mounted eccentrically to the piston guided in slots. The wings seal on the cylinder jacket with movable sliding jaws from and are through annular grooves, in which they engage laterally, -on the cylinder wall held. Here, the one-sided liquid pressure on the wings in the slots of the cylinder have a considerable working resistance. Heavy wear and tear the wing sliding jaws cannot be prevented, which makes the performance proportionate drops rapidly. . -This is how a training is known; at the between one. as a hollow cylinder trained rotary piston and an inner sleeve; which in this eccentric adjustable runs around, a cavity is created, which is delimited by pendulum slides on the one hand hinged in the rotary piston and - on the other hand in the inner sleeve - in semicircular Sliding blocks are articulated. With this arrangement, the radial movements the slide in the sliding jaws under the total pressure of the liquid on them be carried out, which is only possible with considerable frictional losses.

Um das zu vermeiden, sind erfindungsgemäß die Flügel doppelarmig ausgebildet und um im Zylin: der angeordnete, als" zweite Lagerstelle dienende Zapfen schwenkbar. Durch diese Anordnung erhält jede Seite der Flügel den halben Flüssigkeitsdruck, so daß die Bewegung der Flügel in den Gleitbacken und die Drehbewegung der Gleitbacken. selbst nahezu drucklos erfolgt.In order to avoid this, the wings are designed with two arms according to the invention and around in the cylinder: the pivotable pin, which is arranged and serves as a "second bearing point". With this arrangement, each side of the wing receives half the fluid pressure, so that the movement of the wings in the sliding blocks and the rotational movement of the sliding blocks. takes place almost without pressure.

Die Erfindung !.erfolgt. durch die Abb. i und* 2 dargestellt. Der angetriebene Zylinder a läuft in -einem mit Flüssigkeit gefüllten Gehäuse um. Die Flügel c Sind doppelarmig ausgebildet und durch seitliche Zapfen bin dem Zylinder a gelagert. Der eine Arm der Flügel dichtet am Zylindermantel ab, während der andere mittels Gleitbacken in den im Zylinder lose umlaufenden Drehkolben e eingreift und diesen zwingt, die Drehung des ,Zylinders mitzumachen. Der Drehkolben e ist auf dem festen, exzentrisch zum Zylinder stehenden Bolzen p lose gelagert. Die Saug- und Druckkanäle i sind in dem umlaufenden Zylinder angeordnet, so daB die Kanäle auf der Saugseite direkt in die Flüssigkeit eintauchen. ' Zwischen' den Enden der Flügel c und dem Drehkolben e bildet sich die Kolbenzelle f. Durch die radiale Verschiebung.des Drehkolbens gegen die Flüge! wird die Flüssigkeit in der Kolbenzelle auf der Druckseite verdrängt und auf der Saugseite eingesogen. Durch eine Verbindung der Kolbenzelle f mit der Flügelzelle h, beispielsweise durch eine Aussparung g in dem einen der Gleitbacken d, arbeiten die Flügelzellen h und die Kolbenzellen f gleichzeitig, wodurch die Pumpenleistung erhöht wird. Durch diese Anordnung der Pumpenteile wird der lichte Durchmesser des. Zylinders beschränkt, wodurch eine hohe Drehzahl und damit eine im Verhältnis zur Größe -der Pumpe hohe Leistung ermöglicht wird.The invention! .Hakes place. represented by fig. i and * 2. The driven cylinder a rotates in a housing filled with liquid. The wings c are designed with two arms and are mounted in the cylinder a by lateral pins b. One arm of the wing seals on the cylinder jacket, while the other engages by means of sliding blocks in the rotating piston e loosely rotating in the cylinder and forces it to join in with the rotation of the cylinder. The rotary piston e is loosely mounted on the fixed bolt p which is eccentric to the cylinder. The suction and pressure channels are arranged in the rotating cylinder, so that the channels on the suction side dip directly into the liquid. The piston cell f is formed 'between' the ends of the wings c and the rotary piston e . Due to the radial displacement of the rotary piston against the flights! the liquid in the piston cell is displaced on the pressure side and sucked in on the suction side. By connecting the piston cell f to the vane cell h, for example through a recess g in one of the sliding jaws d, the vane cells h and the piston cells f work simultaneously, whereby the pump output is increased. This arrangement of the pump parts limits the inside diameter of the cylinder, which enables a high speed and thus a high output in relation to the size of the pump.

Durch die erfindungsgemäß doppelarmige Aus-Bildung der Flügel wird nicht nur.erreicht, daß die Bewegung der Flügel in- den Gleitbacken und die Drehbewegung der Gleitbacken drucklos erfolgt und Infolgedessen die Reibung und damit Abnutzung der abdichtenden Organe wesentlich verringert wiTd, sondern es erhalten auch aaerdem die Lagerung' des 'Zylinders und der Drehzapfen p einen verhältnismäßig geringen Druck, wie auch die tangentiale Belastung des Drehkolbens gering wird. Ein weiterer Vorteil der Erfindung ist darin zu sehen, daß die zwischen den Gleitbacken entstehenden Kolbenzellen f noch zusätzliche Arbeit leisten, während bei der obengenannten bekannten Ausbildung die Bewegung der Schieberenden innerhalb der Innenhülse nutzlos ist.Due to the double-armed training of the wings according to the invention not only. that the movement of the blades in the sliding blocks and the rotary movement the sliding blocks take place without pressure and as a result, the friction and thus wear The sealing organs wiTd significantly decreased, but it also received aaerdem the storage of 'the' cylinder and the pivot p a relatively small Pressure, as well as the tangential load on the rotary piston is low. Another The advantage of the invention is to be seen in the fact that the resulting between the sliding blocks Piston cells f still do additional work, while known in the case of the above Training the movement of the slide ends within the inner sleeve is useless.

Die Fördermenge kann in bekannter Weise geregelt werden, indem man den Drehkolben gegen die Zylinderachse verschiebt, also die Exzentrizität ändert.The flow rate can be regulated in a known manner by moves the rotary piston against the cylinder axis, thus changing the eccentricity.

Die Pumpe wird vorzugsweise zum Aufbau von Flüssigkeitsgetrieben verwendet, wobei eine zweite Pumpe als Motor dient.The pump is preferably used to build fluid gears, with a second pump serving as a motor.
