Abstract
Gegenstand der Erfindung ist ein Wasser-Hochdruckreinigungsgerät mit einem Gehäuse, mit einer vorzugsweise elektromotorischen Antriebseinrichtung (6) mit Antriebswelle (7) und mit einer von der Antriebseinrichtung (6) angetriebenen Hochdruckpumpe (8) für Reinigungswasser bzw. eine Wasser/Reinigungsmittel-Mischung. Dieses Wasser-Hochdruckreinigungsgerät zeichnet sich dadurch aus, daß die Hochdruckpumpe (8) als Innenzahnradpumpe mit innen verzahntem Zahnring (9) und außen verzahntem Ritzel (10) mit unterschiedlicher Anzahl von Zähnen zwischen Zahnring (9) und Ritzel (10) ausgeführt ist. Von besonderem Vorteil ist dabei eine Ausführungsform mit einer Zahnringpumpe, insbesondere einer Gerotorpumpe. The invention relates to a water high-pressure cleaning device with a housing, with a preferably electromotive drive device (6) with a drive shaft (7) and with a high-pressure pump (8) driven by the drive device (6) for cleaning water or a water / cleaning agent mixture. This water high-pressure cleaning device is characterized in that the high-pressure pump (8) is designed as an internal gear pump with an internally toothed toothed ring (9) and an externally toothed pinion (10) with a different number of teeth between the toothed ring (9) and pinion (10). An embodiment with a gerotor pump, in particular a gerotor pump, is particularly advantageous.
