Abstract

Es wird eine Kraftstoffhochdruckpumpe (1) vorgeschlagen, deren Antriebswelle bei der die Lager (39) und (41) einer Antriebswelle (35) zwangsweise von Kraftstoff durchströmt werden und bei denen dadurch die mechanische und thermische Belastbarkeit der Lager und damit der gesamten Kraftstoffhochdruckpumpe (1) deutlich erhöht wird.
