Abstract

Das erfindungsgemässe Pumpenaufnahmegehäuse (30) eines hydraulisch betriebenen Pressgerätes ist kompakt und leicht ausgeführt und verbindet eine Antriebseinheit mit einer Kolbenzylindereinheit (5) und einer Presseinheit. Innerhalb des Pumpenaufnahmegehäuses ist eine Kolbenpumpe (320) mit einem Pumpenflansch (326) direkt auf einen Verbindungszylinder (55) der Kolbenzylindereinheit (5) gepresst verbunden. Der Verbindungszylinder (55) ragt durch eine Pumpendurchführung (313) in der Gehäusewand (300) in das Pumpenaufnahmegehäuse (30) und kontaktiert direkt auf dem Pumpenkolben (321). Dadurch ist das Pumpenaufnahmegehäuse (30) leitungsfrei ausgestaltet, sodass das Innere des Pumpenaufnahmegehäuses (30) hochdruckfrei ist.

Figure imgaf001
The inventive pump receiving housing (30) of a hydraulically operated pressing device is compact and lightweight and connects a drive unit with a piston-cylinder unit (5) and a pressing unit. Within the pump receiving housing, a piston pump (320) is connected to a pump flange (326) pressed directly onto a connecting cylinder (55) of the piston-cylinder unit (5). The connecting cylinder (55) protrudes through a pump passage (313) in the housing wall (300) in the pump housing (30) and contacted directly on the pump piston (321). As a result, the pump housing (30) is designed without a line, so that the interior of the pump housing (30) is free of high pressure.
