Abstract
Description
Die Erfindung betrifft eine regelbare Pumpe, insbesondere eine regelbare Flügelzellenpumpe nach dem Oberbegriff des Anspruchs 1.The The invention relates to a controllable pump, in particular a controllable Vane pump according to the preamble of claim 1.
Eine
Flügelzellenpumpe dieser Art ist zum Beispiel aus der
Die
Ferner
beschreibt die
Die Erfinder der vorliegenden Anmeldung haben herausgefunden, dass es aufgrund der einhubigen Schmierölförderung bei einer Schmiermittelpumpe zur Schmierölversorgung eines Verbrennungsmotors zu einer inneren Kraftentwicklung auf den Stellring kommt, die insbesondere im hohen Drehzahlbereich auf die Verstelleinheit wirkt und die Pumpe in ihrem Abregelverhalten negativ beeinflusst. Hierdurch kann es zu einer Unterversorgung des Verbrennungsmotors mit Schmieröl kommen.The Inventors of the present application have found that it due to the one-stroke lubricating oil production at a lubricant pump for lubricating oil supply a Internal combustion engine to an internal force development on the adjusting ring comes, in particular in the high speed range on the adjustment acts and the pump negatively influenced in their Abregelverhalten. This can lead to a shortage of the internal combustion engine come with lubricating oil.
Der Erfindung liegt daher die Aufgabe zugrunde, eine regelbare Pumpe der eingangs genannten Art so zu verbessern, dass das obige Problem der inneren Kraftentwicklung auf den Stellring gelöst oder zumindest vermindert ist.Of the Invention is therefore based on the object, a controllable pump of the type mentioned above to improve so that the above problem solved the internal force development on the collar or at least diminished.
Diese Aufgabe wird durch eine regelbare Pumpe mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.These The object is achieved by a controllable pump having the features of the claim 1 solved. Advantageous embodiments and further developments of Invention are the subject of the dependent claims.
Die erfindungsgemäße regelbare Pumpe weist auf: ein Gehäuse; einen im Gehäuse drehbar um eine Welle angeordneten Rotor mit mehreren Fördermitteln; einen den Rotor mit seinen Fördermitteln umgebenden Stellring, dessen Lage im Gehäuse relativ zum Rotor veränderbar ist, um ein Volumen einer zwischen dem Stellring und dem Rotor gebildeten Förderkammer zu verändern; eine mit Förderdruck beaufschlagte Verstelleinrichtung, die auf den Stellring wirkt, um seine Lage relativ zum Rotor in einer ersten Richtung zu verändern; eine Rückstellfeder, die auf den Stellring wirkt, um seine Lage relativ zum Rotor in einer zur ersten Richtung entgegengesetzten zweiten Richtung zu verändern; und eine hydraulische Verbindung zwischen der Förderkammer und einer auf den Stellring in der zweiten Richtung wirkenden Wirkfläche.The controllable pump according to the invention comprises: a Casing; one in the housing rotatable about a shaft arranged rotor with a plurality of funding; a the Rotor with its funding surrounding collar, whose Location in the housing relative to the rotor changeable is to a volume of a feed chamber formed between the collar and the rotor to change; one loaded with delivery pressure Adjustment device that acts on the adjusting ring to its location to change relative to the rotor in a first direction; a return spring, which acts on the adjusting ring to his Position relative to the rotor in a direction opposite to the first direction to change the second direction; and a hydraulic connection between the delivery chamber and one on the adjusting ring in the second direction acting effective area.
Durch die hydraulische Verbindung zwischen der Förderkammer und einer auf den Stellring in der zweiten Richtung wirkenden Wirkfläche wirkt auf diese Wirkfläche ebenfalls der Förderdruck der Pumpe, sodass die innere Kraftentwicklung auf den Stellring zumindest teilweise kompensiert bzw. korrigiert werden kann. Die Größe der so erzeugten Korrekturkraft kann über die Größe der Wirkfläche bestimmt werden.By the hydraulic connection between the delivery chamber and a working surface acting on the adjusting ring in the second direction acts on this effective area also the delivery pressure the pump, so that the internal force on the adjusting ring at least partially compensated or corrected. The size the correction force thus generated can be determined by the size the effective area are determined.
Diese Korrektur bzw. Kompensation der inneren Kraftentwicklung auf den Stellring wird mit einer einfachen und kompakten Anordnung erzielt, die keiner zusätzlichen elektrischen Regelung bedarf und ausfallsicher ist.These Correction or compensation of the internal force development on the Adjusting ring is achieved with a simple and compact arrangement, which requires no additional electrical regulation and failsafe.
Die Wirkfläche kann zum Beispiel durch eine Teilaußenfläche des Stellrings oder ein mit dem Stellring (mechanisch) verbundenes Zusatzelement gebildet sein.The Active surface can, for example, by a partial outer surface of the adjusting ring or one with the adjusting ring (mechanically) connected Additional element be formed.
Ferner kann die hydraulische Verbindung zum Beispiel als eine Durchbrechung im Stellring, ein Kanal im Gehäuse oder eine externe Hydraulikleitung ausgebildet sein.Further For example, the hydraulic connection can be considered as an opening in the collar, a channel in the housing or an external hydraulic line be educated.
Obige sowie weitere Merkmale und Vorteile der Erfindung werden aus der nachfolgenden Beschreibung von bevorzugten, nicht-einschränkenden Ausführungsbeispielen der Erfindung unter Bezugnahme auf die beiliegenden Zeichnungen besser verständlich. Darin zeigen:Above and other features and advantages of the invention will become apparent from the following description of preferred, non-limiting embodiments of the invention with reference to the accompanying drawings better understandable. Show:
Die vorliegende Erfindung wird nachfolgend anhand einer regelbaren Flügelzellenpumpe mit einem translatorisch verschiebbaren Stellring beschrieben, die als Schmiermittelpumpe für einen Verbrennungsmotor eingesetzt wird.The The present invention will be described below with reference to a controllable vane pump described with a translationally movable collar, the used as a lubricant pump for an internal combustion engine becomes.
Die Erfindung ist aber selbstverständlich nicht nur auf diese spezielle Ausführungsform der regelbaren Pumpe beschränkt. Insbesondere ist die Erfindung auch auf eine Flügelzellenpumpe mit einem schwenkbaren Stellring anwendbar. Ferner kann die Erfindung auch bei einer Innenzahnradpumpe anstelle der Flügelzellenpumpe eingesetzt werden.The Of course, invention is not just about this limited special embodiment of the variable pump. In particular, the invention is also directed to a vane pump applicable with a pivoting collar. Furthermore, the invention even with an internal gear pump instead of the vane pump be used.
