Abstract (en)
[origin: WO2010091699A1] The invention relates to a motor pump unit for a high-pressure cleaning device, comprising an electric motor and a pump, the electric motor having a motor housing which is surrounded by a cooling housing, forming an annular chamber with an annular chamber inlet and an annular chamber outlet. The pump has a suction inlet that is connected to the annular chamber outlet and a pressure outlet. The liquid that is to be delivered by the pump can be supplied to the annular chamber inlet and the interior of the cooling housing has at least one flow guide rib for guiding the liquid in the annular chamber. To improve the motor pump unit in such a way that no liquid can escape from the annular chamber, even on a long-term basis, the flow guide rib or ribs is or are at a distance from the motor housing.
