  • Publication number: 20110189909
    Abstract: The present invention relates to an adjustable propeller arrangement comprising a drive shaft extending in a longitudinal direction and an adjustable propeller connected to the drive shaft. The adjustable propeller comprises at least one propeller blade and an adjusting member connected to the at least one propeller blade such that the pitch if the at least one propeller blade is controlled by the position, in the longitudinal direction, of the adjusting member. The arrangement comprises a conduit assembly which in turn comprises a duct located outside of the drive shaft and the conduit assembly further comprises a first conduit portion extending at least partially within the drive shaft. The conduit assembly is adapted to provide a fluid communication between the adjustable propeller and the duct.

  • Publication number: 20110189018
    Abstract: The present invention relates to a propeller comprising a boss with a boss diameter and at least one propeller blade. The propeller further comprises an adjusting member, adapted to be displaced along a first dimension, and a transformation arrangement connecting the adjusting member to the propeller blade such that a displacement, in the first dimension, of the adjusting member results in a change in the pitch of the propeller blade. The transformation arrangement comprises a slot comprising a slot portion with a slot center extending in a slot extension direction which direction is arcuate with a radius of curvature. The transformation arrangement further comprises a control element slidably engaged with at least the slot portion.

  • Patent number: 6139272
    Abstract: A device is used in a hydraulic machine of the type which comprises a runner or rotor with a hub body and vanes or blades which are rotatably journalled in bearings in the hub body, and which has at least one chamber which communicates with the bearings. The device comprises an oil supply to the bearings and elements for leading oil away from the chamber at pace with the supply of oil, such that the chamber is caused to contain an essentially constant volume of oil, which is smaller than the total volume of the chamber, which oil volume is pressed towards the peripheral wall of the chamber by the centrifugal force at the rotation of the runner.

  • Patent number: 6042337
    Abstract: A Kaplan turbine or similar hydraulic machine has a hub body (1) fixed to the turbine shaft with radial blades attached to the hub body. The blades are fitted with oil lubricated bearings in the hub body. A sealing arrangement for the oil system has first (60) and second (61) circumferential sealing members with a circumferential space (65) between the first and second sealing members (60, 61). High pressure water from a water source is directed into the circumferential space (65) via a connecting channel (64) to block the lubricating oil from leaking into the working fluid.
