Abstract (en)
[origin: EP1108892A2] The pump has a ventilation channel (9) connecting the pump interior (3a) to the atmosphere. A lubricant feed pipe (6) has a section (6a), which partially extends through the pump drive shaft (3b), and the ventilation channel opens into this section. During a complete rotation of the drive shaft, this feed pipe section overlaps via an angle segment only, with another feed pipe section (6c). This second section extends in the pump housing area (3c) surrounding the drive shaft, and opens into the pump interior.
