摘要： A centrifugal separator comprises a centrifuge rotor (1), which has a wall (10) defining an interior of the rotor (1) and which during operation of the centrifugal separator is rotatable about a rotational axis (y) with respect to a stationary pipe member (2) comprising at least one passage for the transport of material. The pipe member (2) is provided to extend into the interior of the centrifuge rotor through an aperture of the rotor (1). A product separated during operation is collected in a chamber (9) provided in the proximity of said aperture and partly defined by an end wall portion (11) extending around said aperture and the pipe member (2) in such a manner that a clearance gap is formed between a radially inner edge of the end wall portion (11) and the pipe member (2). The end wall portion (11) is arranged to be deformable in the case that the pipe member contacts the end wall portion during the operation of the separator.

摘要： Method and device (21) for the supply of control liquid to a rotor of a centrifugal separator, which device (21) includes 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). Furthermore, the invention includes 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.
