Abstract
Bei einer Kolbenpumpe (1) mit mindestens einem zumindest annähernd radial zu einer Antriebswelle (3) verschiebbar geführten Pumpenkolben (8), der über eine in einem Rollschuh (12) drehbar gelagerte Laufrolle (13) auf einer Nockenbahn (7) der Antriebswelle (3) abgestützt ist und dadurch in einer Hubbewegung angetrieben ist, und mit einer Druckfeder (16), die sowohl den Pumpenkolben (8) in Anlage an dem Rollenschuh (12) als auch die Laufrolle (13) über den Rollenschuh (12) in Anlage an der Nockenbahn (7) hält, drückt erfindungsgemäß die Druckfeder (16) auf einen Kolbenhalter (14), der an dem Pumpenkolben (8) gehalten ist und in Druckrichtung (17) der Druckfeder (16) sowohl an dem Pumpenkolben (8) als auch an dem Rollenschuh (12) anliegt.In a piston pump (1) with at least one at least approximately radially to a drive shaft (3) slidably guided pump piston (8) via a roller (12) rotatably mounted roller (13) on a cam track (7) of the drive shaft (3 ) is supported and thereby driven in a lifting movement, and with a compression spring (16), both the pump piston (8) in contact with the roller shoe (12) and the roller (13) via the roller shoe (12) in abutment the cam track (7) holds, according to the invention presses the compression spring (16) on a piston holder (14) which is held on the pump piston (8) and in the pressure direction (17) of the compression spring (16) both on the pump piston (8) and rests against the roller shoe (12).
Description
Die Erfindung geht aus von einer Kolbenpumpe nach der Gattung des Anspruchs 1.The The invention is based on a piston pump according to the preamble of the claim 1.

solche Kolbenpumpe ist beispielsweise durch die
Vorteile der ErfindungAdvantages of the invention
Erfindungsgemäß ist ein im Pumpengehäuse geführter Stößelkörper nicht mehr erforderlich. Der an dem Pumpenkolben gehaltene Kolbenhalter gewährleistet einerseits die Anlage des Pumpenkolbens an den Rollenschuh und andererseits die Anlage der Laufrolle über den Rollenschuh an der Nockenbahn. Diese beiden Funktionen werden in herkömmlichen Kolbenpumpen durch den im Pumpengehäuse geführten Stößelkörper und den Federteller bereitgestellt.According to the invention a guided in the pump housing plunger body not necessary anymore. The held on the pump piston piston holder guaranteed on the one hand the system of the pump piston to the roller shoe and on the other the system of the roller over the roller shoe on the cam track. These two functions are used in conventional piston pumps through the plunger body guided in the pump housing and the spring plate provided.
