Abstract

Gegenstand der Erfindung ist eine Kolbenpumpe (3) mit einer Mehrzahl von Kolben-Zylinder-Einheiten (30) und einer Getriebeanordnung (34,35), welche die Drehbewegung einer gemeinsamen Antriebswelle (33) in eine periodisch oszillierende translatorische Hubbewegung der Kolben (32) in den jeweiligen Zylindern (31) umsetzt. Zur Reduzierung der Ungleichförmigkeiten im Förderstrom der Pumpe (3), die bedingt sind durch die einzelnen, zeitlich gegeneinander versetzten Förderhübe der Kolben (32), ist die Getriebeanordnung (34,35) derart ausgebildet, vorzugsweise unter Verwendung eines Nockenprofils (34), daß bei jedem Kolben (32) das Förderintervall einen größeren Teil der Oszillationsperiode belegt als das Saugintervall. Vorzugsweise wird zur Minimierung der Ungleichförmigkeit das Größenverhältnis von Förderintervall zu Saugintervall gleich oder annähernd gleich (2z-1) zu 1 bei z-Zylindern bemessen, gewünschtenfalls unter Hinzufügung eines zusätzlichen Korrekturfaktors zur Kompensation von Leckage und gegebenenfalls anderen Erscheinungen, die weitere Ungleichförmigkeiten im Förderstrom verursachen können.

Figure 00000001
The invention relates to a piston pump (3) with a plurality of piston-cylinder units (30) and a gear arrangement (34, 35) which convert the rotary movement of a common drive shaft (33) into a periodically oscillating translatory stroke movement of the pistons (32). implemented in the respective cylinders (31). In order to reduce the non-uniformities in the delivery flow of the pump (3), which are caused by the individual delivery strokes of the pistons (32) which are offset in time, the gear arrangement (34, 35) is designed, preferably using a cam profile (34), that for each piston (32) the delivery interval occupies a larger part of the oscillation period than the suction interval. In order to minimize the non-uniformity, the size ratio of the delivery interval to the suction interval is dimensioned equal or approximately equal (2z-1) to 1 for z-cylinders, if necessary with the addition of an additional correction factor to compensate for leakage and possibly other phenomena which cause further non-uniformities in the delivery flow can.
