Abstract:
A device which supplies a liquid under pressure to a member having at least one flow passage (13), through which this liquid is passing and which is kept filled up with the liquid, in a shaft suspension device (1) of a centrifugal separator having a shaft, the shaft suspension device having a stationary casing (3) and a unit being composed of parts, which are rotatable around a rotational axis, and non-rotatable parts, and being resiliently supported in the casing (3) by means of at least one elastical element (10) in such a way that the unit during operation is allowed to oscillate relative to the casing while it is influenced by the elastical element (10) with an essentially radially inwardly directed spring force which causes a damping influence by the elastical element (10) on the oscillating movements of the unit, said member forming a part of the composed unit, comprisinga first supply channel portion (19), which is connected to a liquid source (16) for the supply of said liquid under pressure, and which extends through the stationary casing (3),a second supply channel portion (21), for transmitting said liquid under pressure, is connected to the first supply channel portion (19), and extends through the elastical element (10), anda third supply channel portion (23), for transmitting said liquid under pressure, is connected to the second supply channel portion (21), and extends through a non-rotatable part in the composed unit, and has an outlet opening (24) in said flow passage (13).
