Vacuum pump such as mono vane pump used in motor car, has friction portions that are arranged in friction surfaces and are formed of uncoated aluminum material comprising silicon content and hard material particles

The vacuum pump (1) has friction pairing portions (41-44) that are provided with friction surfaces (21,22,31,32,51,52,61,62). The friction surfaces of friction pairing portions are moved with respect to each other, during operation of the vacuum pump. Several friction portions (5-8) are arranged in...

Beschreibung
Zusammenfassung:	The vacuum pump (1) has friction pairing portions (41-44) that are provided with friction surfaces (21,22,31,32,51,52,61,62). The friction surfaces of friction pairing portions are moved with respect to each other, during operation of the vacuum pump. Several friction portions (5-8) are arranged in the friction surfaces. The friction portions are formed of uncoated aluminum material comprising silicon content and hard material particles. Die Erfindung betrifft eine Vakuumpumpe mit mindestens einer Reibpaarung, die zwei Reibflächen umfasst, die an Reibpartnern vorgesehen sind und im Betrieb der Vakuumpumpe relativ zueinander bewegt werden. Die Erfindung zeichnet sich dadurch aus, dass beide Reibpartner aus einem unbeschichteten Aluminiummaterial gebildet sind.
