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.The high pressure plunger pump is designed so that it is simple, simple to assemble components that have a good seal between ensure the work and suction room.

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.In the space between the pump head (2) and the one containing the work space Inner body (3) is a valve seat ring (9) with valve seat surfaces for the pressure valve (11) and for the suction valve (12). One with a central overflow hole equipped suction valve body and an associated spring (14) are in a cylindrical recess of the inner body adjoining the valve seat ring (3) arranged. The pump head (2) is screwed (5) to the inner body (3) connected.

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.An insert sleeve is used to seal the work area from the suction area (19) is provided, in which the plunger (17) is slidably mounted. The seal between the working space and the suction space is carried out by a seal (25) in the Transition area from the sleeve body to the ring flange (20) of the insert sleeve is arranged.

Die Hochdruckplungerpumpe wird in hydrodynamisch arbeitenden Reinigungsgeräten verwendet.
