Abstract:
1. A separator comprising: a rotatable centrifugal drum having a vertical axis of rotation; a rotatable drive spindle to drive the drum; an hydraulic system located in an interior of the drum; at least one feed line to feed a control fluid to the drum, the at least one feed line having an outlet region; 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; a centrifugal ring arranged on the drive spindle below the outlet region of the feed line; wherein the feed line leads out radially in front of the drive spindle in the outlet region, the outlet region being oriented and configured such that emerging control fluid is spread directly against a portion of the drive spindle having a constant diameter, the constant diameter portion lying at least between the ring and the centrifugal ring, and a portion of the control fluid enters through the gap into the hydraulic system; and further wherein an area lying between the outlet region of the feed line and the constant diameter portion of the drive spindle defines an open region having no intervening deflecting structure situated between the outlet region of the feed line and the constant diameter portion of the drive spindle.
