Abstract

Die Erfindung betrifft eine Pumpe mit wenigstens einer Förderanordnung, die einen in einem Zylinder axial geführten Plungerkolben umfaßt, der mit seinem antriebsfernen Ende das Volumen in einer Druckkammer variiert, die beim Saughub mit wenigstens einer auf der der Druckkammer gegenüberliegenden Seite des Plungerkolbens gelegenen Einlaßöffnung und beim Druckhub über eine Druckventilanordnung mit zumindest einer Auslaßöffnung kommuniziert, wobei der Plungerkolben an seinem antriebsfernen Ende eine Saugventilanordnung trägt, die ein axial fest mit einer Kolbenstange verbundenes Kopfteil und eine zwischen dem Plungerkolben und dem Kopfteil axial frei bewegliche Saugventilplatte umfaßt, die beim Saughub am Kopfteil anliegend eine beim Druckhub verschlossene Strömungsverbindung von der Einlaßöffnung über den Plungerkolben in die Druckkammer freigibt.
