A device for the supply of a liquid under pressure to a flow passage (,) in a member in a shaft suspension unit (,) of a centrifugal separator, which has a stationary casing (,) and a unit, which is resiliently and oscillation dampingly suspended in the casing (,) by at least one elastical element (,), the member forming a part of the composed unit. To be able to supply liquid to the member in a sample manner with a certain controllable flow which is made sure under overpressure a first supply channel portion (,) is connected to a liquid source (,) for the supply of liquid under pressure extending through the stationary casing (,). To the first supply channel portion (,) there is connected a second supply channel portion (,) extending through the elastical element (,). A third supply channel portion (,) is connected to the second supply channel portion (,), extending through the non-rotatable part of the composed unit and having an outlet opening (,) in the flow passage (,).
