Abstract
Die Erfindung betrifft eine Kolbenpumpe mit einem Pumpengehäuse (7), das mehrere die Funktion der Kolbenpumpe bestimmende Pumpenbauteile wie einen abschnittsweise geführten Pumpenkolben (6), eine Kolbenrückstellfeder sowie ein Saug- und Druckventil aufweist, mit einem den Pumpenkolben (6) saugseitig begrenzenden, als Nachlaufraum (12) für die Flüssigkeit ausgeführten Ringraum und mit einem den Pumpenkolben (6) druckseitig begrenzenden Förderraum, sowie mit einem elastischen Dichtring (1) zur Abdichtung des Pumpenkolbens (6) in Richtung eines Pumpenantriebsraums (13). Zur Verhinderung einer Leckage in Richtung des Pumpenantriebsraums (13) ist der elastische Dichtring (1) mit einer Nut (3) versehen, in der ein den Dichtring (1) auf den Pumpenkolben (6) anpressendes Federelement (2) eingesetzt ist.The invention relates to a piston pump with a pump housing (7), which has a plurality of the function of the piston pump pump components such as a partially guided pump piston (6), a piston return spring and a suction and pressure valve, with a pump piston (6) on the suction side limiting, as Overflow space (12) for the liquid running annulus and with a pump piston (6) on the pressure side limiting delivery chamber, and with an elastic sealing ring (1) for sealing the pump piston (6) in the direction of a pump drive space (13). In order to prevent leakage in the direction of the pump drive space (13), the elastic sealing ring (1) is provided with a groove (3) in which a spring element (2) pressing against the sealing ring (1) on the pump piston (6) is inserted.
Description
Die Erfindung betrifft eine Kolbenpumpe, insbesondere zur Druckmittelförderung in hydraulischen Bremsanlagen mit Schlupfregelung, nach dem Oberbegriff des Patentanspruchs 1. The invention relates to a piston pump, in particular for pressure medium delivery in hydraulic brake systems with slip control, according to the preamble of
Aus
Daher ist es die Aufgabe der vorliegenden Erfindung, eine Kolbenpumpe der angegebenen Art derart zu verbessern, dass weniger, möglichst kompakte Bauteile benötigt werden, sowie gleichzeitig eine verbesserte Abdichtung entlang der Mantelfläche des Pumpenkolbens gewährleistet wird.Therefore, it is the object of the present invention to improve a piston pump of the specified type such that fewer, compact components are needed, and at the same time an improved seal along the lateral surface of the pump piston is ensured.
Diese Aufgabe wird erfindungsgemäß für eine Kolbenpumpe der angegebenen Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. This object is achieved for a piston pump of the type indicated with the characterizing features of
Weitere Merkmale und Vorteile der Erfindung gehen im nachfolgenden aus der Beschreibung zweier Ausführungsbeispiele anhand von Zeichnungen hervor.Further features and advantages of the invention will become apparent hereinafter from the description of two embodiments with reference to drawings.

Analog zu
Zusammenfassend ergibt sich somit auf der dem Kolbenantriebsraum
- – längere leckagefreie Pumpenlaufzeiten,
- – bessere Dichtwirkung des
Dichtrings 1 in allen Temperaturbereichen, - – drastische Bauteilreduzierung,
- – einfachere und kostengünstigere Bauteilmontage,
- – kleinere axiale Toleranz des Einbauraums des
Dichtelements 1 aufgrund der reduzierten Bauteilanzahl (wichtig für die Reduzierung des Pumpenverschleißes und die Verbesserung des Pumpenwirkungsgrades), - – Entfall der zusätzlichen Befettung/Ölbenetzung des
Dichtelements 1 zum Zwecke der Trockenlauf-Pumpenprüfung.
- - longer leakage-free pump running times,
- - Better sealing effect of the
sealing ring 1 in all temperature ranges, - - drastic component reduction,
- - simpler and less expensive component assembly,
- - Smaller axial tolerance of the installation space of the
sealing element 1 due to the reduced number of components (important for reducing pump wear and improving pump efficiency), - - Elimination of the additional lubrication / oil wetting of the
sealing element 1 for the purpose of dry-running pump testing.
