Abstract (en)
The pump (1) has a drive shaft (35) supported in pump housing by bearings (39, 41), and a pump unit (21), which is arranged radially relative to the drive shaft. A conveying pump (5) e.g. external gear pump, conveys fuel to a fuel inlet (15) and a metering unit (19) regulates conveying amount of the pump unit (21). The metering unit and a pressure regulating valve (20) are supplied with the fuel by a fuel return line (18). A non-return valve (43) is provided downstream to the bearing (39) and another non-return valve (45) is provided downstream to the bearing (41).
Abstract (de)
Es wird eine Kraftstoffhochdruckpumpe (1) vorgeschlagen, bei der die Lager (39 und 41) der Antriebswelle (35) zwangsweise von Kraftstoff durchströmt werden und bei der dadurch die mechanische und thermische Belastbarkeit der Lager und damit der gesamten Kraftstoffhochdruckpumpe (1) deutlich erhöht wird.
