Centrifuge, in particular separator, having a feed line for control fluid

A separator includes a rotatable centrifugal drum having a vertical axis of rotation. The separator includes a rotatable drive spindle to drive the drum, an hydraulic system located in an interior of the drum and at least one feed line to feed a control fluid to the drum, the at least one feed line having an outlet region. Further included is a ring non-rotatably connected to the drum, a gap located between one of the drive spindle and the drum and the drive spindle and the ring. The feed line leads out radially in front of the drive spindle in the outlet region. The outlet region is oriented and configured such that emerging control fluid is spread directly against the drive spindle, and a portion of the control fluid enters through the gap into the hydraulic system.
