PUMP ARRANGEMENT, FUEL DELIVERY SYSTEM AND LIQUID COOLING SYSTEM FOR AN INTERNAL COMBUSTION ENGINE INCORPORATING SUCH A PUMP AND A VEHICLE COMPRISING SUCH A FUEL DELIVERY SYSTEM AND LIQUID COOLING SYSTEM |
摘要 |
A pump arrangement is disclosed having a housing, a first pumping chamber within the housing, a drive shaft carried by the housing, and first pumping means arranged for rotation within the first pumping chamber. The first pumping means is driven by the drive shaft. A second pumping chamber accommodating a second pumping means is separated from the first pumping chamber by the housing such that the housing forms common separation wall. To provide a compact arrangement in which the first and second pumping chambers are reliably sealed from each other, the second pumping means is driven by the drive shaft via a magnetic coupling. Thus, the coupling comprises a drive rotor connected to the drive shaft and a driven rotor carried by the housing. The driver rotor and the driven rotor are separated by a separation wall assembly serving as a static seal to hermetically seal the second pumping chamber from the drive shaft.
