Abstract (en)

[origin: WO9727945A1] Method and device (21) for the supply of control liquid to a rotor of a centrifugal separator, which device (21) comprises a cylinder (25), in which a movable wall element (26) is arranged, which axially delimits a storing chamber (29) in the cylinder (25). In the storing chamber (29) a predetermined volume of control liquid is stored. Control liquid is pressed out of the storing chamber (29) into the rotor during axial displacement of the wall element (26). Futhermore, the invention comprises a centrifugal separator, which is provided with such a device (21). A portion of the control liquid in the storing chamber (29) is pressed upon displacement of the wall element (26) a first distance out through a first outlet passage (33) in the device with a high flow. The first outlet passage (33) is then closed when the wall element (26) has been displaced this distance. A portion of the remaining control volume of control liquid in the storing chamber (29) is pressed out of the storing chamber (29) upon continuing displacement of the wall element (26) a second distance through a second outlet passage (36) in the supplying device (21) with a flow, which is substantially lower than the first flow.
