Abstract

Die Hochdruckplungerpumpe ist so gestaltet, daß sie sich aus wenigen, einfach zu fertigenden Bauteilen zusammensetzt, die eine gute Abdichtung zwischen dem Arbeits- und Saugraum gewährleisten.
In dem Raum zwischen dem Pumpenkopf (2) und dem den Arbeitsraum enthaltenden Innenkörper (3) ist ein Ventilsitzring (9) mit Ventilsitzflächen für das Druckventil (11) und für das Saugventil (12) vorgesehen. Ein mit einer mittigen Überströmbohrung ausgerüsteter Saugventilkörper und eine zugeordnete Feder (14) sind in einer an den Ventilsitzring angrenzenden, zylindrischen Ausnehmung des Innenkörpers (3) angeordnet. Der Pumpenkopf (2) ist durch Schrauben (5) mit dem Innenkörper (3) verbunden.
Zur Abdichtung des Arbeitsraumes gegenüber dem Saugraum ist eine Einsteckhülse (19) vorgesehen, in der der Plunger (17) gleitbar gelagert ist. Die Abdichtung zwischen dem Arbeitsraum und dem Saugraum erfolgt durch eine Dichtung (25), die im Übergangsbereich von dem Hülsenkörper zum Ringflansch (20) der Einsteckhülse angeordnet ist.
Die Hochdruckplungerpumpe wird in hydrodynamisch arbeitenden Reinigungsgeräten verwendet.
